The great albatrosses are seabirds in the genus Diomedea in the albatross family. The genus Diomedea formerly included all albatrosses except the sooty albatrosses, but in 1996 the genus was split, with the mollymawks and the North Pacific albatrosses both being elevated to separate genera. The great albatrosses themselves form two species complexes, the wandering and Amsterdam albatrosses, and the royal albatrosses. The splitting of the great albatrosses into six or seven species has been accepted by most, though not all authorities.
|
|
The sooty albatrosses are small albatrosses from the genus Phoebetria. There are two species, the sooty albatross, Phoebetria fusca, and the light-mantled albatross, Phoebetria palpebrata.
|
|
The Antipodean albatross (Diomedea antipodensis) is a large seabird in the albatross family. Antipodean albatrosses are smaller than wandering albatrosses, and breed in predominantly brown plumage, but are otherwise difficult to distinguish from young wanderers (wandering albatrosses grow lighter in color with age, while the Antipodean stays darker).
|
|
Wandering albatrosses travel vast distances and tend to feed further out in open oceans than other albatrosses, whereas the related royal albatrosses in general tend to forage in somewhat shallower waters and closer to continental shelves.Imber (1999). Diet and Feeding Ecology of the Royal Albatross Diomedea epomophora - King of the Shelf Break and Inner Slope. Emu 99(3) 200–211 They also tend to forage in colder waters further south than other albatrosses.
|
|
The North Pacific albatrosses are large seabirds from the genus Phoebastria in the albatross family. They are the most tropical of the albatrosses, with two species (the Laysan and black-footed albatrosses) nesting in the Northwestern Hawaiian Islands, one on sub-tropical islands south of Japan (the short-tailed albatross), and one nesting on the equator (the waved albatross).
|
|
The feeding habits of these albatrosses are similar to other albatrosses in that they eat fish, squid, crustacea, and carrion. Observations made during June 2010 from the Hokkaido University research vessel the Oshoro Maru in the western North Pacific showed an apparent symbiotic relationship between a school of 57 ocean sunfish (Mola mola) and Laysan and black-footed albatrosses. The sunfish were infected with the mesoparasitic copepods from the genus Pennella and the albatrosses were seen to remove these parasites from the sunfish which appeared to be actively attempting to attract the albatrosses. When roosting, they choose isolated sites and lay one egg, with both parents incubating and raising the chick.
|
|
Their taxonomy is very confusing, as with all albatrosses. It is widely accepted now, based on molecular evidence and the fossil record, that they are a distinct genus from Diomedea in which formerly most "white" albatrosses were placed but which is now restricted to the "great" albatrosses. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns.
|
|
The great albatrosses range across the Southern Ocean, and nest (for the most part) on isolated oceanic islands. The wandering albatrosses nest on islands around the Southern Ocean, from the Atlantic Ocean (South Georgia and Tristan da Cunha), to the Indian Ocean and New Zealand's Subantarctic islands. The royal albatrosses nest only on New Zealand's Subantarctic islands, with one unusual colony on New Zealand's Otago Peninsula.

Twenty percent of the world population of black-footed albatrosses breed on Pearl and Hermes The Pearl and Hermes Atoll is an important nesting area for many seabirds. Approximately 160,000 birds from 22 different species are known to live and breed on the Atoll. Tristram's storm petrels and black-footed albatrosses are among the most prominent. In 2001, it was reported that twenty percent of the world's population of black-footed albatrosses nested on Pearl and Hermes.

The great albatrosses are predominantly white in plumage as adults, with birds becoming whiter as they age. The two royal albatrosses at all ages and the larger, older male wandering albatrosses are totally white-bodied, while adult females and younger animals of the other species have dark pencilling marks on the edges of their feathers. Generally the smaller species or subspecies and the juveniles have more dark brown colour. The recently discovered Amsterdam albatross retains the dark brown plumage of juvenile birds into adulthood.

The origins of the NSWASG lie in the pioneer albatross banding activities started by Doug Gibson and Allan Sefton in 1956 at Bellambi in the Illawarra region, and by Bill Lane and Harry Battam in 1958 at Malabar, some 56 km further north in south-eastern Sydney. This followed the realisation that large concentrations of great albatrosses appeared in winter off the New South Wales coast not far from Sydney, and raised the possibility among local amateur ornithologists of catching useful numbers at sea for banding. Black- browed albatrosses also occurred in similar numbers, but wandering albatrosses were considered easier to catch because of their "more phlegmatic disposition", so the banding programs focussed on the latter. At the time there were thought to be only two great albatross species – the wandering and royal albatrosses, with the royal (now split into northern royal and southern royal albatrosses) not known to occur along the coast of eastern Australia.

This squid is preyed upon by sea birds, marine mammals, and fish. Southern elephant seals prey minimally on G. glacialis and equally on males and females. Likewise, they have been recorded to only prey on adults rather than juveniles. Black-browed albatrosses and grey-headed albatrosses also prefer feeding on adults more than juveniles.

Wandering albatrosses performing their mating dances on the Kerguelen Islands Procellariiforms are monogamous breeders and form long-term pair bonds. These pair bonds take several years to develop in some species, particularly with the albatrosses. Once formed, they last for many breeding seasons, in some cases for the life of the pair. Petrel courtship can be elaborate.

Black-browed Albatross hooked on a long-line. The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a legally binding international agreement signed in 2001 and entered into force on 1 February 2004 when South Africa ratified as the fifth Party to the Agreement. It was created in order to halt the drastic decline of seabird populations in the Southern Hemisphere, particularly of albatrosses and petrels. Albatrosses and petrels are threatened by introduced species on their breeding islands, pollution, and by being taken as bycatch by longline fisheries, as well as by trawl and gillnet fisheries.

Wandering albatross The New South Wales Albatross Study Group (NSWASG) was an amateur ornithological fieldwork group that banded albatrosses and other seabirds off the coast of eastern New South Wales, Australia. Primarily targeting winter feeding aggregations of wandering albatrosses near Sydney, it developed its own catching methods and initiated what has become the longest- running continuous albatross research study in the world.

Australian giant cuttlefish The Bellambi site attracted large numbers of albatrosses because of the seasonal abundance of breeding aggregations of a favoured prey species, the Australian giant cuttlefish, with the albatrosses feasting both on live cuttlefish and the debris from predation by dolphins. At Malabar the attraction was the presence of a major submarine sewage outfall which, during the 1950s, discharged large quantities of meaty and fatty wastes from abattoirs and tanneries and acted as a feeding station for albatrosses and other seabirds. According to local ornithologist Keith Hindwood, "Towards the end of April or early in May there is a large influx [of wandering albatrosses], and for the next six months it is not unusual to record from 100 to upwards of 400 birds close to the sewer outlets or resting on the water near the drift-line extending for half a mile or more from the cliffs".

Duvsete : 323 Despite the leap in technology, the Albatrosses were soon declared obsolete. Allied Forces Northern Europe determined that they needed full anti-submarine capabilities and opted to replace the flying boats with the Lockheed P-3 Orion.Duvsete : 325 Five Orions were capable of the same job as eighteen Albatrosses, and the number of squadrons was cut to one. The 330 Sqn was therefore deactivated on 1 October 1968.

Both species have a white incomplete eye-ring, dark bills and grey feet. They are among the smallest albatrosses, with wingspans of and are very narrow as well. The light-mantled, at and sometimes to , is larger than the sooty, at . Unique amongst the albatrosses they have long stiff wedge shaped tails, the purpose of which is unclear but seems to be related to their ability to dive for food.

The Gibson Plumage Index (GPI), sometimes known as the Gibson Code, is a system for describing the plumage of great albatrosses. It is named after, and originally devised in the late 1950s by, John Douglas Gibson and other members of the New South Wales Albatross Study Group. Gibson was an Australian amateur ornithologist who carried out fieldwork on albatrosses along the coast of New South Wales for thirty years. The index assigns separate numerical values (from 1 to 6 with increasing proportion of white) to the degrees of colouration on four parts of the body - the back, head, inner wing and tail - of albatrosses to indicate variations in age and between different breeding populations.

The Albatross about my Neck was Hung: 1896 etching by William Strang illustrating Coleridge's 1798 poem The Rime of the Ancient Mariner The most important family culturally is the albatrosses, which have been described by one author as "the most legendary of birds".Carboneras, C. (1992) "Family Diomedeidae (Albatross)" in Handbook of Birds of the World Vol 1. Barcelona:Lynx Edicions, Albatrosses have featured in poetry in the form of Samuel Taylor Coleridge's famous 1798 poem The Rime of the Ancient Mariner, which in turn gave rise to the usage of albatross as metaphor for a burden. More generally, albatrosses were believed to be good omens, and to kill one would bring bad luck.

In Alaska, residents of Kodiak Island harpoon short-tailed albatrosses, Diomedea albatrus, and until the late 1980s residents of Tristan Island in the Indian Ocean harvested the eggs of the Yellow-nosed Mollymawks, Diomedea chlororhynchos, and sooty albatrosses, Phoebetria fusca. Albatrosses and petrels are also now tourist draws in some locations, such as Taiaroa Head. While such exploitation is non- consumptive, it can have deleterious effects that need careful management to protect both the birds and the tourism. The English naturalist William Yarrell wrote in 1843 that "ten or twelve years ago, Mr. Gould exhibited twenty-four [storm petrels], in a large dish, at one of the evening meetings of the Zoological Society".

Procellariiformes is an order of seabirds that comprises four families: the albatrosses, petrels and shearwaters, and 2 families of storm petrels. Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order,Warham, J. (1996). The Behaviour, Population, Biology and Physiology of the Petrels. London: Academic Press, or more commonly all the families except the albatrosses.

A semi-precocial wedge-tailed shearwater chick with guarding parent The majority of procellariiforms nest once a year and do so seasonally.Brooke, 2004. p. 46 Some tropical shearwaters, like the Christmas shearwater, are able to nest on cycles slightly shorter than a year, and the large great albatrosses (genus Diomedea) nest in alternate years (if successful). Most temperate and polar species nest over the spring-summer, although some albatrosses and procellariids nest over the winter.
|
|
The flora and fauna are considered similar to other southern Antarctic marine regions. Particularly in Summer, the nutrient-rich sea water supports an abundant planktonic life in turn providing food for larger species, such as fish, seals, whales, and sea- and shore-birds. Albatrosses rely on wind to travel and cannot get airborne in a calm. The westerlies do not extend as far south as the ice edge and therefore albatrosses do not travel often to the ice-pack.
|
|
The Campbell albatross is very similar but with a pale eye. Immature birds are similar to grey-headed albatrosses but the latter have wholly dark bills and more complete dark head markings.
|
|
From albatrosses and other seabirds the use of geolocators has been extended to other migratory species, including waders, wildfowl, raptors and songbirds as designs have become gradually smaller and more energy efficient.

The family name for albatrosses, Diomedeidae, and the genus name for the great albatrosses, Diomedea, originate from Diomedes. On San Nicola Island of the Tremiti Archipelago there is a Hellenic period tomb called Diomedes's Tomb. According to a legend, the goddess Venus seeing the men of Diomedes cry so bitterly transformed them into birds (Diomedee) so that they could stand guard at the grave of their king. In Fellini's movie 8½, a cardinal tells this story to actor Marcello Mastroianni.

This high efficiency of sodium ion absorption is attributed to mammalian-type nephrons. Most albatrosses and procellariids use two techniques to minimise exertion while flying, namely, dynamic soaring and slope soaring. The albatrosses and giant petrels share a morphological adaptation to aid in flight, a sheet of tendon which locks the wing when fully extended, allowing the wing to be kept up and out without any muscle effort. Amongst the Oceanitinae storm-petrels there are two unique flight patterns, one being surface pattering.

Nesocichla eremita, the Tristan thrush. Tristan is primarily known for its wildlife. The island has been identified as an Important Bird Area by BirdLife International because there are 13 known species of breeding seabirds on the island and two species of resident land birds. The seabirds include northern rockhopper penguins, Atlantic yellow-nosed albatrosses, sooty albatrosses, Atlantic petrels, great-winged petrels, soft-plumaged petrels, broad-billed prions, grey petrels, great shearwaters, sooty shearwaters, Tristan skuas, Antarctic terns and brown noddies.

One product of the research was the Gibson Plumage Index, developed to categorise the variation in plumage colouring and, with the measurements, indicating differences between island populations. Heads of "great albatrosses" The "Wanderer" group of albatrosses has been split into several taxa including, as well as the wandering albatross, the Antipodean, Gibson's, Tristan and Amsterdam albatrosses, not all of which are recognised by all authorities. Although the taxonomy is still in flux, the work of the group was instrumental in first indicating the genetic isolation of several island breeding populations. The group was eventually subsumed into, and its work continued by, the Southern Oceans Seabird Study Association (SOSSA), established in 1994 by members of the NSWASG as an umbrella organisation for many groups involved in studies of the biodiversity of the Southern Ocean.

Albatross Island () is an island southeast of Cape Buller, lying in the Bay of Isles, South Georgia. Charted in 1912-13 by Robert Cushman Murphy, American naturalist aboard the brig Daisy, who gave this name because he observed albatrosses there. The eastern headland of the island is called The Pricker, a name which first appeared on a 1931 British Admiralty chart. The island is rat-free and there is a breeding population of South Georgia pipits here, along with wandering albatrosses and giant petrels.

Light-mantled albatrosses share some identifying features with other Procellariiformes. They have nasal tubes on the upper bill called naricorns, though with albatrosses these are on the sides of the upper mandible rather than the top. They also have a salt gland above the nasal passage which excretes a concentrated saline solution to maintain osmotic balance, due to the amount of seawater imbibed.Ehrlich, Paul R. (1988) The bills of the Procellariiformes are unique in that they are covered with from seven to nine horny plates.

Meanwhile, eight Sopwith Camels of No. 10 Squadron Royal Naval Air Service, led by Flight Lieutenant Fitzgibbon, were escorting a number of DH-4 bombers back to Allied lines. Somewhere in the vicinity of Moorslede, Belgium, Fitzgibbon spotted a flight of German Albatrosses below them and led half of his men to attack. The remaining Camels stayed with the bombers and were attacked by Wolff. In the confusion of the dogfight, the British pilots mistakenly thought that five Albatrosses and four triplanes were involved.

The chief mate defied the captain (who had threatened him with a harpoon), and launched a lifeboat with the help of volunteers. As a number of albatrosses circled over Luckner, one swooped down and seized his outstretched hand in its beak, but Luckner grabbed the bird in desperation. Although severely pecked, he hung on for his life. The flapping of the bird's huge wings and the circling of the other albatrosses gave the crew of the lifeboat a point to aim at in his rescue.

The albatrosses in particular have been the subject of numerous cultural depictions. Procellariiforms include some of the most endangered bird taxa, with many species threatened with extinction due to introduced predators in their breeding colonies, marine pollution and the danger of fisheries by- catch. Scientists, conservationists, fishermen, and governments around the world are working to reduce the threats posed to them, and these efforts have led to the signing of the Agreement on the Conservation of Albatrosses and Petrels, a legally binding international treaty signed in 2001.

The island has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds, of which there are at least 26 breeding species. Birds nesting in relatively large numbers include king, northern rockhopper and macaroni penguins, wandering, sooty and light-mantled albatrosses, northern giant petrels, medium-billed prions, Kerguelen and soft-plumaged petrels, and South Georgia diving petrels. Other island breeders in smaller numbers are southern giant petrels, grey-headed albatrosses and Kerguelen terns. Crozet blue-eyed shags, black-faced sheathbills and Eaton's pintails are resident.

After ending service in Norway the Albatrosses were transferred to the Hellenic Air Force, here depicting an ex-Norwegian heritage aircraft The 333 Sqn had continued to operate the Catalinas through the 1950s, although they by the end of the decade were all but modern. The Norwegian authorities agreed to receive eighteen Grumman HU-16B-ASW Albatrosses through the Marshall Plan. These flying boats were intended for maritime surveillance and transport to Svalbard,Duvsete : 319 as well as submarine sweeping.Duvsete : 321 330 and 333 Sqn would receive nine airframes each.

The short-tailed albatross or Steller's albatross (Phoebastria albatrus) is a large rare seabird from the North Pacific. Although related to the other North Pacific albatrosses, it also exhibits behavioural and morphological links to the albatrosses of the Southern Ocean. It was described by the German naturalist Peter Simon Pallas from skins collected by Georg Wilhelm Steller (after whom its other common name is derived). Once common, it was brought to the edge of extinction by the trade in feathers, but with protection has recently made a recovery.

The two species, like most seabirds, are colonial, although they are less colonial than the other species of albatrosses. In fact, on some breeding islands (like Tristan da Cunha) they may nest in very small groups or clusters of two to five nests, and the light-mantled will even nest singly. This is in part due to the influence of humans, and in part due to their tendency to nest on cliffs, unlike the flatter ground preferred by other albatrosses. Both species build cone shaped nests and lay a single egg.

It excretes a high saline solution from their nose.Ehrlich, Paul R. (1988) Going back in time, fossils of albatrosses from the mid- Pleistocene in Bermuda and North Carolina are considered to be closest to the short-tailed albatross.

Many sperm whales have scars on their backs, believed to be caused by the hooks of colossal squid. Colossal squid are a major prey item for sperm whales in the Antarctic; 14% of the squid beaks found in the stomachs of these sperm whales are those of the colossal squid, which indicates that colossal squid make up 77% of the biomass consumed by these whales. Many other animals also feed on colossal squid, including beaked whales (such as the southern bottlenose whale), pilot whales, southern elephant seals, Patagonian toothfish, sleeper sharks (Somniosus antarcticus), and albatrosses (e.g., the wandering and sooty albatrosses).
|

Due to the difficulty in distinguishing them from wandering albatrosses, their distribution at sea is still not fully known, but the use of satellite tracking has shown that they forage widely in the South Atlantic, with males foraging west of the breeding islands towards South America and females to the east towards Africa. There have been sightings near Brazil and also off the coast of Australia. Tristan albatrosses are endemic to the islands of the Tristan da Cunha group and more specifically Gough Island. The majority of the world's population nest on Gough Island, around 1500 pairs.

Black-browed albatross hooked on a long-line The principal threat to the albatrosses and larger species of procellariids is long-line fishing. Bait set on hooks is attractive to foraging birds and many are hooked by the lines as they are set. As many as 100,000 albatrosses are hooked and drown each year on tuna lines set out by long-line fisheries.BirdLife International/RSPB (2005) Save the Albatross: The Problem Retrieved March 17, 2006 Before 1991 and the ban on drift-net fisheries, it was estimated that 500,000 seabirds a year died as a result.

Mosquitoes bite the waved albatrosses, directly leading to or transmitting diseases that cause nestling mortality, colony migration, or egg desertion in albatrosses. Experimental studies show that both sexes can survive on a sugar-only diet for 2–3 months, but females require blood meals for egg production. In females, supplementation of a blood meal in autogenous mosquitoes increased both egg production and lifespan. Additional observational studies of Ae. taeniorhynchus in nature showed that habitat impacts the effect of the meal source: females inhabiting mangrove swamps could produce eggs even without blood meals, but those from a grassy salt marsh environment could not.

The southern royal albatross eats squid and fish, with smaller amounts of carrion, crustaceans, and salps. Its foraging activities normally take place within a 1250 km radius of the breeding site.Waugh, S., Troup, C., Filippi, D., & Weimerskirch, H. (2002). Foraging zones of Southern Royal albatrosses.

Albatrosses nesting in fernbrush on Nightingale Island Nightingale Island is known as a breeding ground for various types of seabirds; over a million birds are estimated to breed on the island, with great shearwaters being among the most abundant. There are four wetland areas on the island which each contain hundreds of Atlantic yellow-nosed albatrosses. As with Inaccessible Island, Nightingale also has a breeding colony of northern rockhopper penguins, now an endangered species, with a fraction of the 1950s population remaining. The island is part of the Nightingale Islands group Important Bird Area (IBA), identified as such by BirdLife International as a breeding site for seabirds and endemic landbirds.

The western coastline of the island, including the cliffs, has been identified as a 360 ha Important Bird Area (IBA) by BirdLife International because it is home to one of the largest colonies of Indian yellow-nosed albatrosses in the world, with about 19,000 pairs constituting some 20% of the world population, and about 240 pairs of sooty albatrosses. There is also a large colony of northern rockhopper penguins, with 25,000 pairs. Two species, grey and soft-plumaged petrels, which have become rare on the island due to predation by rats and cats, are thought to breed in the IBA. There is a large rookery of subantarctic fur seals in the IBA.

Of these the proportion of retraps from previous years increased annually and it became clear that many birds returned each year. There were also many recoveries of banded birds in South Georgia. The group continued to operate for over thirty years despite the deaths of several of its founders and the end of Malabar as a suitable banding site with improvements in sewage treatment. As well as South Georgia, recoveries of albatrosses banded in New South Wales have been made in the Crozet Archipelago, the Prince Edward Islands, the Antipodes and Auckland Islands, with the body of research, which is ongoing, described as the longest continuous study of albatrosses anywhere in the world.

Many of them eat the abundant krill (which in turn feed on phytoplankton and ice-algae). Humpback whales are shown catching krill through sophisticated co-operation: they create spiralling curtains of air bubbles that drive it into their centre, where the whales can then catch them by surging upwards in the middle of the spiral. Also shown are the various seabirds which feed in the Antarctic sea, especially albatrosses, whose impressive wingspans are possible because they utilise the updraft generated by the huge waves in the stormy southern waters. Because of the patchiness of krill, albatrosses can travel for many hundreds or indeed thousands of miles on a single trip in search of it.

The aspect ratios of birds' and bats' wings vary considerably. Birds that fly long distances or spend long periods soaring such as albatrosses and eagles often have wings of high aspect ratio. By contrast, birds which require good maneuverability, such as the Eurasian sparrowhawk, have wings of low aspect ratio.

No significant land sits at the latitudes of the Drake Passage. That is important to the unimpeded flow of the Antarctic Circumpolar Current, which carries a huge volume of water through the passage and around Antarctica. The passage hosts whales, dolphins and seabirds including giant petrels, other petrels, albatrosses and penguins.

In dynamic soaring energy is gained by repeatedly crossing the boundary between air masses of different horizontal velocity rather than by rising air. Such zones of high "wind gradient" are usually too close to the ground to be used safely by gliders, but Albatrosses and model gliders use this phenomenon.

Albatrosses are not the only species to suffer from the plastic pollution; sea turtles and monk seals also consume the debris. All kinds of plastic items wash upon the shores, from cigarette lighters to toothbrushes and toys. An albatross on Midway can have up to 50% of its intestinal tract filled with plastic.

Chalk's International Airlines Albatross arriving in Miami Harbor from Nassau, Bahamas, in 1987 In the mid-1960s the U.S. Department of the Interior acquired 3 military Grumman HU-16's from the U.S. Navy and established the Trust Territory Airlines in the Pacific to serve the islands of Micronesia. Pan American World Airways and finally Continental Airlines' Air Micronesia operated the Albatrosses serving Yap, Palau, Chuuk (Truk) and Pohnpei from Guam until 1970, when adequate island runways were built, allowing land operations. In 1970, Conroy Aircraft marketed a remanufactured HU-16A with Rolls-Royce Dart turboprop engines as the Conroy Turbo Albatross, but only one prototype was ever built. Many surplus Albatrosses were sold to civilian operators, mostly to private owners.

Lindsay E. Smith OAM is an Australian naturalist, ornithologist and conservationist notable for his work towards the study and conservation of seabirds, especially albatrosses, along the Illawarra coast of New South Wales. Although much of his career has been as a fitter and turner, he was employed by the Australian Museum in 1987 as an ornithologist to work at the Elizabeth and Middleton Reefs in Australia's Coral Sea Islands Territory. In 1994 he was the founder, with Harry Battam, of the Southern Oceans Seabird Study Association, the inheritor of the long-term research work on albatrosses off the New South Wales coast begun by the New South Wales Albatross Study Group in 1956, and the longest continuous seabird study in the world.

Julian Alan Lowther Hector was born in 1958 in Nairobi, Kenya and educated at Bedford Modern School. He read Zoology at the University of Bristol graduating in 1981, obtained a PhD from Bristol in 1985 and was made an honorary Doctor of Science by the University of Bristol in 2014. In the later stage of his days as an undergraduate, Hector worked as a seabird ecologist with the British Antarctic Survey in South Georgia, an unpopulated British island 1400 km from the Falkland Islands. The project involved studying the breeding patterns of Albatrosses on Bird Island under the ultimate directorship of John Croxall and Sir Brian Follett. The project's work was ‘pioneering’ and uncovered why Albatrosses only breed every two years.

It has been suggested that it would have flown similar to modern-day soaring birds such as albatrosses, which consisted of flying very long distances and rarely flapping. The species N. gracilis and N. nanus have previously been considered as species of the closely related Pteranodon, back then known as P. gracilis and P. nanus, due to their similarities.

Individuals on the west coast of Africa could be confused with vagrant masked boobies, though the latter is smaller overall, lacks the buff tinge to the head, and has a black tail. From a distance, or in poor visibility, albatrosses can be confused with northern gannets, particularly those with immature plumage that have more black on the wings.

Sometimes, breeding groups are shared with other bird species such as the rock shag, southern rockhopper penguin, and black-browed albatrosses. This species is known for smaller colonies, usually with 20-40 pairs. Still some larger colonies, up to 800 pairs, have been observed. Both genders help create a nest made from feathers, seaweed, and ocean debris.

ACAP helps countries to implement species action plans, control the expansion of non-native predators, introduce measures reducing bycatch of seabirds, and support research in the sphere of the effective conservation of petrels and albatrosses. To this end it has published ACAP Species Assessments, booklets, mitigation factsheets, and a number of ACAP Conservation Guidelines, including for biosecurity; eradication of introduced mammals; translocation; and census and survey methods. One of the Agreement's main activities is to provide expert advice on seabird bycatch mitigation to fisheries managers, both in domestic and high seas fisheries. In May 2019 the ACAP Advisory Committee declared that a conservation crisis continues to be faced by its 31 listed species, with thousands of albatrosses, petrels and shearwaters dying every year as a result of fisheries operations.

The large number and range of birds is also of interest to scientists and tourists. Around 56 species live in the archipelago, of which 27 are found only in the Galápagos. Some of these are found only on one island. The most outstanding are penguins, which live on the colder coasts, Darwin's finches, frigatebirds, albatrosses, gulls, boobies, pelicans and Galápagos hawks, among others.

Juvenile on Nightingale Island Like all albatrosses they are colonial, but unusually they will build their nests in scrub or amongst Blechnum tree ferns. Like all mollymawks they build pedestal nests of mud, peat, feathers, and vegetation to lay their one egg in. They do this in September or early October, and the chick fledges in late March to April. They breed annually.

Pterosaurs like Boreopterus are interpreted by Unwin as soaring animals, like today's albatrosses and frigatebirds. However, it has also been suggested that boreopterids foraged while swimming, trapping small prey with their needle-like teeth,Mark Witton, 2011 a method similar to that of modern Platanista dolphins. It has been suggested that the closely related Zhenyuanopterus was merely the adult form of this animal.

Numerous seabird taxa breed no further north(east)wards than San Benedicto; storm-petrels are notably absent as breeders though they breed in the region and visit the islands to forage. Albatrosses are also not normally found here.

The resources used to support the detachment made the 330 Sqn almost unable to provide sweeping operations. The Albatrosses improved the sweeping capacity and introduced news technology such as sonar, radar and magnetic anomaly detector. Norway did not have capacity to sweep its waters and instead focused on the surveillance. This allowed both British and American forces to carry out such tasks.

In Argentina, dusky dolphins associate closely with southern right whales and South American sea lions. They have been found around bottlenose dolphins, but apparently do not interact with them, and may share feeding areas with Risso's dolphins. They also associate with various seabirds, such as kelp gulls, cormorants, terns, shearwaters, petrels, and albatrosses. In New Zealand, dusky dolphins mingle with common dolphins.

However albatrosses are not able to reach the adults because they cannot deep-dive. Tissue degeneration and upwelling bring mature squids up to the surface of the water for predation. Digested parts of G. glacialis have been found in the stomachs of a species of icefish native to the Southern Ocean. Galiteuthis glacialis are opportunistic feeders and prey upon whatever is available.

The Antipodes group has been identified as an Important Bird Area (IBA) by BirdLife International because of its significance as a breeding site for several species of seabirds. The seabirds are southern rockhopper and erect-crested penguins, Antipodean, black-browed, light-mantled and white-capped albatrosses, and northern giant, grey and white-chinned petrels.BirdLife International. (2012). Important Bird Areas factsheet: Antipodes Islands.

It continued its flight, apparently untired, in tempestuous as well as moderate weather. The Maori of New Zealand used albatrosses as a food source. They caught them by baiting hooks. Because the wing bones of albatross were light but very strong Maori used these to create a number of different items including koauau (flutes), needles, tattooing chisel blades, and barbs for fish hooks.

The plant community dominated by P. flabellata is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly found in this habitat on the Falkland Islands, with tussocks being used as nesting sites.Collar (2005) pp.

The Agreement requires that measures be taken by signatory governments to reduce bycatch; protect breeding colonies; and control and remove introduced species from breeding sites, especially on islands. Currently, ACAP protects all the world's albatross species, seven Southern Hemisphere petrel species and two shearwater species. The ongoing work of the Agreement reflects an increasing international commitment to protect albatrosses and petrels.

Ornithoteuthis volatilis, a common squid from the tropical Indo-Pacific, is predated by yellowfin tuna, longnose lancetfish, common dolphinfish and swordfish, the tiger shark, the scalloped hammerhead shark and the smooth hammerhead shark. Sperm whales also hunt this species extensively as does the brown fur seal. In the Southern Ocean, penguins and wandering albatrosses are major predators of Gonatus antarcticus.

The poorly known New Zealand storm petrel was considered extinct for 150 years before being rediscovered in 2003. The albatrosses and petrels are "amongst the most severely threatened taxa worldwide". They face a variety of threats, the severity of which varies greatly from species to species. Several species are among the most common of seabirds, including Wilson's storm petrel (an estimated 12 to 30 million individuals) and the short-tailed shearwater (23 million individuals); while the total population of some other species is a few hundred. There are less than 200 Magenta petrels breeding on the Chatham Islands, only 130 to 160 Zino's petrels and only 170 Amsterdam albatrosses. Only one species is thought to have become extinct since 1600, the Guadalupe storm petrel of Mexico, although a number of species had died out before this.

The Nightingale Islands group has been recognised internationally as part of the Tristan da Cunha Endemic Bird Area (EBA). It has also been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds and its endemic landbirds. Birds for which the IBA is significant include northern rockhopper penguins (up to 125,000 breeding pairs), sooty albatrosses (up to 250 pairs), Atlantic yellow-nosed albatrosses (5000 pairs), broad-billed prions (10,000 pairs), soft-plumaged petrels (up to 1000 pairs), great shearwaters (up to 3 million pairs), white-faced storm petrels (10,000 pairs), white-bellied storm petrels (1000 pairs), Antarctic terns (up to 400 pairs), southern skuas (up to 500 pairs), Tristan thrushes, Wilkins's buntings and Nightingale buntings. The nearby islands of a Gough and Inaccessible Island have been recognised as Wetlands of International Importance under the Ramsar Convention.

Their quadrate bone articulation with the lower jaw resembled that of a pelican or other birds that can open their beak widely. Altogether, the pseudotooth birds would have filled an ecological niche almost identical to that of the larger fish-eating pteranodontian pterosaurs, whose extinction at the end of the Cretaceous may well have paved the way for the highly successful 50-million-year reign of the Pelagornithidae. Like them as well as modern albatrosses, the pseudotooth birds could have used the system of ocean currents and atmospheric circulation to take round-track routes soaring over the open oceans, returning to breed only every few years. Unlike albatrosses today, which avoid the tropical equatorial currents with their doldrums, Pelagornithidae were found in all sorts of climates, and records from around 40 Ma stretch from Belgium through Togo to the Antarctic.

This albatross is an expert in dynamic soaring using the wind gradient. Wind gradient soaring, also called dynamic soaring, is a technique used by soaring birds including albatrosses. If the wind gradient is of sufficient magnitude, a bird can climb into the wind gradient, trading ground speed for height, while maintaining airspeed. By then turning downwind, and diving through the wind gradient, they can also gain energy.

Floyd, Ted (2008) Like all albatrosses, the Laysan albatross is known to be a long-living bird. The oldest known live bird, a female named Wisdom, was at least 64 years old . In 2014 she hatched a healthy chick which is believed to be her 36th. The longest lifespan confirmed for a wild seabird was for a breeding male found to have been banded 53 years previously.

Albatrosses belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns; the nostrils of the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates.

Similar to the Otago Peninsula, the harbor water is known for various rare wildlife. The area is the home of many species of wading birds. Other bird species which visit the harbour include two species of penguins, little penguin and famous yellow-eyed penguins. Taiaroa Head, at the tip of the Otago Peninsula, is home to the northern royal albatrosses only "mainland" colony in the world.

Laysan albatrosses are monogamous. They don't breed until they are eight or nine years old. John Klavitter is a U.S fish and Wildlife Service biologist at Midway and says that when an albatross loses one of their mate the surviving bird “goes through a year or two of a mourning period” before it starts searching again for a new mate, a process that can take many years.

Two species are considered critically endangered: the Amsterdam albatross and the Chatham albatross. One of the main threats is commercial long-line fishing, because the albatrosses and other seabirds which readily feed on offal are attracted to the set bait, after which they become hooked on the lines and drown. An estimated 100,000 albatross per year are killed in this fashion. Unregulated pirate fisheries exacerbate the problem.

While most extant birds have a single seamless rhamphotheca, species in a few families, including the albatrosses and the emu, have compound rhamphothecae that consist of several pieces separated and defined by softer keratinous grooves. Studies have shown that this was the primitive ancestral state of the rhamphotheca, and that the modern simple rhamphotheca resulted from the gradual loss of the defining grooves through evolution.

Species in the bird order Procellariformes have nostrils enclosed in double tubes which sit atop or along the sides of the upper mandible. These species, which include the albatrosses, petrels, diving petrels, storm petrels, fulmars and shearwaters, are widely known as "tubenoses". A number of species, including the falcons, have a small bony tubercule which projects from their nares. The function of this tubercule is unknown.
|
|
They also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. They excrete a high saline solution from their nose, which is a probable cause for the pink-yellow stain seen on some animal's necks.Ehrlich, Paul R. (1988)Tickell, W.L.N. 2011. Plumage contamination on Wandering Albatrosses -an aerodynamic model.

Pairs of wandering albatrosses mate for life and breed every two years. Breeding takes place on subantarctic islands and commences in early November. The nest is a mound of mud and vegetation, and is placed on an exposed ridge near the sea. During the early stages of the chick's development, the parents take turns sitting on the nest while the other searches for food.
|
|
Illegal fishing also brings further risks through the use of techniques banned in regulated fishing, such as gillnetting and longline fishing. These methods increase the bycatch of animals such as albatrosses. Subantarctic islands fall under the jurisdiction of national governments, with environmental regulation following the laws of those countries. Some islands are in addition protected through obtaining the status of a UNESCO World Heritage Site.

This squid is eaten by several predators in the Southern Ocean, like Albatrosses, Sperm whales, Seals and Penguins. Based on stable isotopes analysis, this squid may be a top predator on its natural habitat.Cherel, Y & Ducatez, S & Fontaine, C & Richard, P & Guinet, C. 2008. Stable isotopes reveal the trophic position and mesopelagic fish diet of female southern elephant seals breeding on the Kerguelen Islands.

The wandering albatross and the southern royal albatross are the largest of the albatrosses and are amongst the largest of flying birds. They have the largest wingspans of any bird, being up to from tip to tip, although the average is a little over . Large adult males of these two species may exceed in weight, as heavy as a large swan. Facial features of various Diomedea species.

Amsterdam albatrosses breed biennially in the open marshy ground. Both parents incubate the egg in alternate stints that last for about a week, with the chick hatching after 80 days. The chick is brooded for a month and overall takes 230 days to fledge. At first, it is fed by its parents every three days, with the feeding frequency reduced as it approaches fledging.

Together with her chick, she survived the 2011 Tōhoku earthquake and tsunami that killed an estimated 2,000 adult Laysan and Black-footed albatrosses, and a much larger number of chicks, at the refuge. Wisdom has laid some 30-40 eggs in her lifetime. In December, 2016, Wisdom (at the approximate age of 66) hatched and reared another chick. In December 2017, she was breeding again.

Soon after the Gulf War ended, Lajes command changed from Air Mobility Command, to Air Combat Command. In 1993, squadrons 503 and 752 are merged in a single mixed unit operating both C-212 and Aérospatiale Puma, theis being the 711 Squadron "Albatrozes" (Albatrosses). The resident Portuguese 711 Squadron was deactivated on 30 November 2006. With this act the long-serving Aerospatiale Puma was retired from service.

These energy-intensive processes were not usually available during the Age of Sail. Larger sailing warships with large crews, such as Nelson's , were fitted with distilling apparatus in their galleys. Animals such as fish, whales, sea turtles, and seabirds, such as penguins and albatrosses have adapted to living in a high saline habitat. For example, sea turtles and saltwater crocodiles remove excess salt from their bodies through their tear ducts.

To help the species, other conservation measures have been proposed. Conducting surveys of the breeding population as an ongoing process. Pushing for adoption of the best-practice mitigation measures in fisheries within this birds range, utilizing organizations such as the Food and Agriculture Organization, Agreement on the Conservation of Albatrosses and Petrels, and International Commission for the Conservation of Atlantic Tunas. Restricting access to prevent colonization of introduced species.

Approximately one-third of the chicks die. These deaths are attributed to the albatrosses confusing brightly colored plastic with marine animals (such as squid and fish) for food. Recent results suggest that oceanic plastic develops a chemical signature that is normally used by seabirds to locate food items. Because albatross chicks do not develop the reflex to regurgitate until they are four months old, they cannot expel the plastic pieces.

They caught two albatrosses, one of which they ate, and used pieces as bait to catch fish, all while fending off constant shark attacks and nearly being capsized by a storm. They were strafed a number of times by a Japanese bomber, which punctured their life raft, but no one was hit. After 33 days at sea, McNamara died; Zamperini and Phillips wrapped up his body and pushed it overboard.

They may feed at night or during the day (unlike albatrosses which do not feed at night) (Imber 1976). Birds will aggressively follow fishing boats and long line hooks and may dive up to 20m below the surface after baits (Imber 1976). Black petrels can cover amazing distances – the longest recorded foraging trip for a bird from Great Barrier Island is 39 days (Bell et al. 2009, Bell et al.

Avian Conservation and Ecology, 8(2), 4-10. Major foraging areas for vulnerable seabirds (albatrosses and shearwaters) tend to overlap with world's richest fishing grounds, thus increasing the proportions of accidental bycatch of birds. Fisheries could also indirectly affect the trophic structure and foraging methods of seabirds. Since most sea birds are long-lived and have low reproduction rates, even a small increase in bird mortality could cause significant population declines.

Albatrosses (black-browed, Chatham, yellow-nosed, etc.) are occasionally spotted off the cliffs as are short-tailed shearwaters (particularly during their spring migration), black-faced and pied cormorants, kelp gulls and Australasian gannets. The shrubs decorating the area are frequently home to brown thornbills, singing honeyeaters and a number of other passerines. The elusive striated fieldwren has also been known to inhabit the area. Some flora include cushion bushes.

Polynesian explorers arrived at Enderby Island in the 13th or 14th centuries, about the time mainland New Zealand was settled. Archaeological excavations revealed their presence at Sandy Bay, in a sheltered and relatively hospitable location, accessible to seal colonies. Excavated earth ovens contained the bones of seals and sea lions, fishes, mussels, albatrosses and petrels. The Polynesians stayed for one or more summers and left behind scrapers, tools, and fish hooks.

Plants recorded from the islet include a glasswort (Salicornia australis), New Zealand iceplant, shore groundsel, taupata and a goosefoot (Chenopodium allanii). It is a breeding site for a small colony, only discovered in 1983, of about 20 pairs of northern Buller's albatrosses (Thalassarche bulleri platei), the only known breeding site for the subspecies away from the Chatham Islands. It also has a large colony of red-billed gulls.

A Wandering albatross (Diomedea exulans) on South Georgia The rocky shores of mainland Antarctica and its offshore islands provide nesting space for over 100 million birds every spring. These nesters include species of albatrosses, petrels, skuas, gulls and terns. The insectivorous South Georgia pipit is endemic to South Georgia and some smaller surrounding islands. Ducks, the South Georgia pintail and Eaton's pintail, inhabit South Georgia, Kerguelen and Crozet.

They are able to complete a breeding cycle in under a year, but do not breed in consecutive years, instead taking a year off and returning to breed every two years. Around 22% of the sooty albatrosses survive until adulthood (there are no figures for light-mantled). Both species return to the breeding colony after 7–10 years of fledging, and begin to breed a few years later.

Association of killer whales and black-browed albatrosses Day-to-day killer whale behaviour generally consists of foraging, travelling, resting and socializing. Killer whales frequently engage in surface behaviour such as breaching (jumping completely out of the water) and tail-slapping. These activities may have a variety of purposes, such as courtship, communication, dislodging parasites, or play. Spyhopping is a behaviour in which a whale holds its head above water to view its surroundings.

Waved-albatross Phoebastria irrorata Albatrosses are particularly adept at exploiting these techniques and can travel hundreds of miles using very little energy. Birds that soar dynamically have a skeletal structure that allows them to lock their wings when they are soaring, to reduce muscle tension and effort besides steering. Lord Rayleigh first described dynamic soaring in 1883 in the British journal Nature:Lord Rayleigh (5 April 1883) "The soaring of birds," Nature, vol. 27, no.

In 2005, when Korean and Philippine vessels started longline fishing along the edges of the Agulhas Bank, seabird bycatch became a huge problem. Large numbers of albatrosses and petrels were killed -- in average 0.6 birds per 1000 hooks, but up to 18 birds per 1000 hooks were reported. Since 2007, however, more restrictive permit conditions for foreign-flagged fleets and the use of birds scaring lines have decreased the number of killed birds by 85%.

A marine protected area is defined by the IUCN as "A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values". The Prince Edward Islands MPA is intended to stop the decline of the Patagonian toothfish, which has been critically over-exploited, and to reduce the seabird bycatch of the fishery, particularly of albatrosses and petrels.

The adults have white bodies with black and white wings. Males have whiter wings than females with just the tips and trailing edges of the wings black. The wandering albatross is the whitest of the wandering albatross species complex, the other species having a great deal more brown and black on the wings and body as breeding adults, very closely resembling immature wandering albatrosses. The large bill is pink, as are the feet.

Watkins, B. P.; et, al (2007) Conservation efforts underway start with this species being placed on Convention on Migratory Species Appendix II, and Agreement on the Conservation of Albatrosses and Petrels Annex 1. It is being monitored on half of the islands, and most of the breeding sites are reserves. Heard Island, McDonald Island, Macquarie Island, and the New Zealand islands are World Heritage Sites. An initial Chilean census has also been completed.

Petrels have a plate called the maxillary unguis that forms a hook on the maxilla. The smaller members of the order have a comb-like mandible, made by the tomial plate, for plankton feeding. Most members of the order are unable to walk well on land, and many species visit their remote breeding islands only at night. The exceptions are the huge albatrosses, several of the gadfly petrels and shearwaters and the fulmar-petrels.

The diet of many storm petrels species is poorly known owing to difficulties in researching; overall the family is thought to concentrate on crustaceans.Brooke, M. (2004). Albatrosses and Petrels Across the World Oxford University Press, Oxford, UK Small fish, oil droplets and molluscs are also taken by many species. Some species are known to be rather more specialised; the grey-backed storm petrel is known to concentrate on the larvae of goose barnacles.

Of the 1.5 million Laysan albatrosses that inhabit Midway Atoll, nearly all are likely to have plastic in their gastrointestinal tract. Approximately one-third of their chicks die, and many of those deaths are from plastic unwittingly fed to them by their parents. Twenty tons of plastic debris washes up on Midway every year with five tons ending up in the bellies of albatross chicks. Fish and whales may also mistake the plastic as a food source.

The third tradition claims he disappeared on Diomedea, the uninhabited island (called after him) in the Adriatic where the Shearwaters who were formerly his companions live, which implies some kind of deification. The fourth tradition comes from the Heneti, who claim Diomedes stayed in their country and eventually had a mysterious apotheosis. One Legend says that on his death, the albatrosses got together and sang a song (their normal call). Others say his companions were turned into birds afterwards.

Like many pseudotooth birds, it was initially believed to be related to the albatrosses in the tube-nosed seabirds (Procellariiformes), but subsequently placed in the Pelecaniformes where it was either placed in the cormorant and gannet suborder (Sulae) or united with other pseudotooth birds in a suborder Odontopterygia.Lanham (1947), Brodkorb (1963: p. 262–263), Olson (1985: p.

Terns may be killed or injured by collisions with trawl warps, trapped in trawls or discarded gear, or hooked by longline fishing, but, unlike albatrosses and petrels, there is little evidence that overall numbers are significantly affected. An unusual incident was the incapacitation of 103 terns off Robben Island, South Africa by marine foam, generated by a combination of wave action, kelp mucilage and phytoplankton. After treatment, 90% of the birds were fit to be released.

Size comparison – Gibson's (above) and black-browed albatrosses Similar in appearance to the wandering albatross, adult birds have white on the back, extending along the upper surface of the wings near the body. The white plumage of the head and body has fine grey barring. The upper wing has a black trailing edge, with black flight feathers and with mottled white patches on the black primary coverts. The underwing is white with a dark trailing edge.

No date. Accessed 2012-03-11 The Royal Forest and Bird Protection Society of New Zealand (Forest & Bird) assigns hoki an E grade (red - avoid). Both organisations state damage to the sea floor due to bottom trawling and bycatch of species such as New Zealand fur seals, albatrosses, petrels and basking sharks as the primary reasons for the ratings. In September 2013, as New Zealand Hoki, it continued to appear on the MSC's list of sustainable fish.

Charles Baudelaire's collection of poems Les Fleurs du mal contains a poem entitled "L'albatros" (1857) about men on ships who catch the albatrosses for sport. In the final stanza, he goes on to compare the poets to the birds — exiled from the skies and then weighed down by their giant wings, till death. Finally, in Herman Melville's Moby-Dick. Here is a reference to Coleridge's albatross See The Rime of the Ancient Mariner in popular culture.

Some species of tubenoses (Procellariiformes) such as albatrosses circle the earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, including altitudinal migrations on mountains such as the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the sun and stars, the earth's magnetic field, and mental maps.

Together with the Amsterdam albatross, it forms the wandering albatross species complex. The wandering albatross is one of the two largest members of the genus Diomedea (the great albatrosses), being similar in size to the southern royal albatross. It is one of the largest, best known, and most studied species of bird in the world, with it possessing the greatest known wingspan of any living bird. This is also one of the most far ranging birds.

The shy albatross averages in length, wingspan,Dunn, Jon L. & Alderfer, Jonathan (2006) and in weight. Alongside its similarly sized sister species, the Salvin's albatross, this species is considered the largest of the mollymawks or the small albatrosses.Brooke, Michael, Albatrosses and Petrels across the World (Bird Families of the World). Oxford University Press (2004), It is a black, white and slate-grey bird with the characteristic black thumb mark at the base of the leading edge of the underwing.

The wing sometimes has vestigial claws. In most species, these are lost by the time the bird is adult (such as the highly visible ones used for active climbing by hoatzin chicks), but claws are retained into adulthood by the secretarybird, screamers, finfoots, ostriches, several swifts and numerous others, as a local trait, in a few specimens. Albatrosses have locking mechanisms in the wing joints that reduce the strain on the muscles during soaring flight.Videler, JJ (2005) Avian Flight.

Larger species of petrels will even kill the chicks and even adults of smaller species in disputes over burrows. Burrows and natural crevices are most commonly used by the smaller species; all the storm petrels and diving petrels are cavity nesters, as are many of the procellariids. The fulmarine petrels and some tropical gadfly petrels and shearwaters are surface nesters, as are all the albatrosses. Procellariiforms show high levels of philopatry, both site fidelity and natal philopatry.

It reaches its extreme with the albatrosses, where pairs spend many years perfecting and elaborating mating dances. These dances are composed of synchronised performances of various actions such as preening, pointing, calling, bill clacking, staring, and combinations of such behaviours (like the sky-call). Each particular pair will develop their own individual version of the dance. The breeding behaviour of other procellariiforms is less elaborate, although similar bonding behaviours are involved, particularly for surface- nesting species.

It is found in the Pitcairn Islands, and possibly in French Polynesia, though confusion over the taxon makes reports of this species in the Marquesas, Tuamotus, Australs and Gambiers uncertain.Michael Brooke, Albatrosses and petrels across the world, Oxford University Press, 2004 p.334. Breeding colonies formerly existed on Ducie Island, but were wiped out by invasive rats by 1922. It is now believed to nest uniquely on Henderson island, which was declared a World Heritage Site in 1988.

In the 1970s the airport became part of the new network of regional airports in Lofoten and Vesterålen with government subsidised operations using de Havilland DHC-6 Twin Otter aircraft seating 20 and operated by Widerøe. In 1969 the Albatrosses were replaced by P-3B Orion aircraft. The P-3B lacked the ability to work with the Norwegian Coast Guard, and in 1989 they were sold to Spain. They were replaced with new P-3C aircraft.

The bay is home to temporary colonies of King Penguins and a variety of other birds, such as petrels or albatrosses, which nest in the cliffs of the bay, as well as colonies of South American sea lions and Southern elephant seal. Rabbit were deliberately introduced in 1874, and have since been observed in the cliffs of Port-Christmas. Southern right whales have also be seen near the bay, and on the North-Western shores of the archipelago.

A chick just before it left the Hawaiian archipelago Short-tailed albatrosses now nest on four islands, with the majority of birds nesting on Torishima, and almost all of the rest on Minami-kojima in the Senkaku Islands. A female-female pair began nesting on Kure in the late 2000s, but to date they have not produced a viable egg. A chick hatched on 14 January 2011 on Midway. Both Midway and Kure are in the Northwestern Hawaiian Islands.

The Amsterdam albatross is listed as critically endangered, by the IUCN, with an occurrence range of and a breeding range of only . The population upon discovery was just five breeding pairs; with conservation this has increased to eighteen to twenty- five breeding pairs. Monitored continuously since 1983,Agreement on the Conservation of Albatrosses and Petrels (ACAP), Species assessment: Amsterdam Albatross Diomedea amsterdamensis, 2010. the world population is estimated at 80 mature individuals and a total of some 130 birds.

Harrisoniella hopkinsi is a species of phtilopterid louse that lives on and eats the feathers of albatrosses. The species was first described by W. Eichler in 1952. This species is dark brown with an elongated head, and extremely large – H. hopkinsi is one of the largest feather lice, with males reaching up to long. They live mostly on the wing feathers, but are quite able to move if disturbed or if their host bird should die.

On December 3, 2014, Wisdom made headlines when she laid an egg at the Midway Atoll. Her mate had arrived at the atoll on November 19 and Wisdom was first spotted by the refuge staff November 22. The egg was estimated to be number 36 for Wisdom over her lifetime. Albatrosses lay one egg per year and have monogamous mates for life. In nine years from 2005 to 2014, Wisdom laid an egg for eight of them.

This is also seen in many inland soaring birds, which have a lower aspect ratio compared those that soar over the ocean. Huge genera such as Tropeognathus and Ornithocheirus are considered to have flown similar to modern-day albatrosses, which consisted on travelling very long distances and rarely flapping. This technique is mostly seen in later pterosaur locomotion, such as the related and mentioned pteranodontids, though not so common in the larger azhdarchids such as Hatzegopteryx and Quetzalcoatlus.

Prior to 2001, 1380 black footed albatross and 1163 Laysan albatrosses were caught annually by the Hawaii longline fishery. The WPRFMC's response to the volume of seabirds being caught was to mount a project through 1998 and 1999 to test various seabird mitigation methods. It was found that during gear setting operations, blue dyed baits were the most successful mitigation method, followed by strategic offal discards. Tori lines and a towed buoy system also proved to be effective mitigation measures during the set.

The climate is very dry, like most of the Archipelago. But due to the flatness of the island, it is the driest of these islands, with only a few inches of rain per year. It is about a 10- to 12-hour trip by boat from Isla Santa Cruz. Tourists come to see the waved albatrosses (from March to January, almost the entire world population breeds on the island) and the mating dances of blue- footed boobies on Española Island.

Birds of prey have a very high density of receptors and other adaptations that maximise visual acuity. The placement of their eyes gives them good binocular vision enabling accurate judgement of distances. Nocturnal species have tubular eyes, low numbers of colour detectors, but a high density of rod cells which function well in poor light. Terns, gulls and albatrosses are amongst the seabirds which have red or yellow oil droplets in the colour receptors to improve distance vision especially in hazy conditions.

The largest of the group is Evangelistas Grande which is about long and wide, reaches a height of and supports the lighthouse. The other, uninhabited, islets are Elcano , Lobos , and Pan de Azúcar . They are mainly bare rock with steep cliffs on their western sides and are exposed to strong winds and rough seas. Lobos and Elcano are home to breeding colonies of black- browed albatrosses with a combined estimate of 4670 pairs recorded in a 13 October 2002 aerial survey.

Visitors can interact with the animals at the Sea Turtle Feeding Pool, Sting Ray Lagoon, Swim with the Sea Lions and Swim with Dolphins pools. The Dolphin Cove Show features an open-air theater from which visitors can watch dolphin performances. The Bird Sanctuary is home to many wild marine birds including "iwa" (great frigatebirds), boobys, shearwaters, and albatrosses, most of which came to the sanctuary sick or injured. Visitors can see how these birds are cared for and rehabilitated.

An estimated 10% contained pearls. Based on those findings, the surveyors concluded that Captain Anderson must have harvested between 150,000-200,000 oysters to obtain his reported 20,000 pearls, which had significantly depleted the oyster beds. The Whippoorwill expedition documented wildlife aside from the oysters: Dr. Galtsoff's report indicated that they had found seals, sharks, sea turtles, albatrosses, booby birds, and numerous species of fish. They did not find any of the trees which Captain Brooks had mentioned in his 1857 report.

The program's goal is to inform visitors of the dangers that ocean plastic pollution causes for animals, especially the 21 species of albatrosses. Pacific bluefin and yellowfin tunas have been historically displayed in the Open Sea community exhibit, some reaching more than . In 2011, three dozen fishes of the two species were on exhibit. Prior to opening the Open Sea wing in 1996, the aquarium established the Tuna Research and Conservation Center in 1994 in partnership with Stanford University's Hopkins Marine Station.

As the waved albatross glides higher it loses most of its ground speed because it is gliding into a wind of a higher speed. However, its air speed does not fall, enabling it to glide continuously. However, waved albatrosses do have difficulty in landing due to their high stalling speed, and in taking off due to the challenge of beating their massive wings. To make it easier they sometimes take off from cliffs that are somewhat inland rather than beside the coast.

On their breeding islands, Gibson's albatrosses nest on moss terraces and in tussock grassland on or near ridges, slopes and plateaus where an exposed, windy position helps them take off. They often form loose colonies on the windward sides of the islands. Breeding takes place only every two years, if successful; studies on Adams Island in the 1990s found an annual breeding success rate of 67%. Albatross pairs return to their breeding islands from November, with the older males the first to arrive.

It excretes a high saline solution from their nose.Ehrlich, Paul R. (1988) The white-capped albatross is part of a greater complex of albatrosses consisting of the shy albatross, Thasassarche cauta, Salvin's albatross, Thalassarche salvini, and Chatham albatross, Thalassarche eremita. In 1998, Robertson and Nunn recommended a four-way split,Robertson C. J. R. & Nunn G. B. (1998) some experts agreed. BirdLife International agreed in 2007,BirdLfie International (2008a) ACAP agreed in 2006,ACAP (2006) and Brooke agreed in 2004.

They exhibit strong philopatry, returning to their natal colony to breed and returning to the same nesting site over many years. Procellariiforms are monogamous and form long-term pair bonds that are formed over several years and may last for the life of the pair. A single egg is laid per nesting attempt, and usually a single nesting attempt is made per year, although the larger albatrosses may only nest once every two years. Both parents participate in incubation and chick rearing.

Mathews renamed it Pterodroma atrata, since dark-plumage birds of this species were considered to be dark- morphed herald petrels. It was only as late as 1996 that evidence was provided that these birds were specifically distinct from pale-morph herald petrels.Michael Brooke, Albatrosses and petrels across the world, Oxford University Press, 2004 p.333. Millions of pairs of Henderson petrel used to breed on the island several centuries ago. Brooke calculated breeding pairs to be around 16,000 in 1991/2.

Michael John "Mike" Imber (November 1940 – 28 April 2011) was a New Zealand ornithologist known for his research work and expertise on petrels. Imber worked for the New Zealand Department of Conservation for 40 years, (including 21 years with its predecessor, the Wildlife Service) as a seabird and waterfowl biologist, retiring in 2006.Pterodroma Pelagics. One of his main early areas of research was on the cephalopod diets of petrels and albatrosses, using regurgitated squid beaks to identify prey taxa.

Most Ae. taeniorhynchus rely on mammals and birds for blood meals, especially depending on bovine, rabbits, and armadillos. Mosquitoes in the Galapagos Islands feed on mammals and reptiles, with equal preference but feed little on birds. Since this differs from the typical feeding of Ae. taeniorhynchus on birds, studies suggest the species is an opportunistic feeder, in which it feeds more on the most readily available, easily accessible organisms. Ae. taeniorhynchus acts as an ectoparasite to Diomedea irrorata, known as waved albatrosses.

With the arrival of the Cold War 582nd Resupply Group in 1953, the station was modernised with the construction of a 9,000 feet jet runway and permanent facilities, overlaid over the Second World War Eighth Air Force airfield. This configuration existed until about 1980.

A ferry sails multiple times a day from the town of Triabunna to the jetty in Darlington Bay at the northern end of Maria Island, a distance by sea of 16 km or nearly nine nautical miles. In winter, some sailings are subject to demand, while in summer extra sailings are provided. A previous ferry operation out of Louisville (near Orford) is now defunct. Common dolphins, Australian fur seals and seabirds such as Australasian gannets and shy albatrosses are often seen on the voyage.

The need for salt excretion in reptiles (such as marine iguanas and sea turtles) and birds (such as petrels and albatrosses) reflects their having much less efficient kidneys than mammals. Unlike the skin of amphibians, that of reptiles and birds is impermeable to salt, preventing its release. The evolution of a salt gland in early reptiles and birds allowed them to eat aquatic plants and animals with high salt concentrations. This evolutionary development does not account for the gland in elasmobranchs, suggesting convergent evolution.

Kenneth (Ken) Nigel Graham Simpson (1938 – 9 July 2014) was an Australian ornithologist and ornithological writer best known as the coauthor, with artist Nicolas Day, of the Simpson & Day field guide to Australian birds. Simpson was born in Sydney and educated at University High School in Melbourne. He subsequently worked as a research technician in various institutions as well as lecturing in primary science at Deakin University and leading birdwatching tours. During the mid-1960s he studied royal penguins and wandering albatrosses on subantarctic Macquarie Island.

Bird Island Nature Reserve in Lambert's Bay, Western Cape, South Africa. A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows.

The pigs have destroyed much of the islands' flora, though remnant plant communities of Pleurophyllum, Stilbocarpa, and Anisotome are relatively safe because they are only accessible on cliffs where the pigs cannot go. Since the depletion of many plant food resources, the pig population on Auckland Island has remained relatively low. The feral pigs have also had negative effects on other wildlife throughout the island. They have dug up burrows of birds to steal their eggs such as petrels, albatrosses, mollymawks, penguins, and shags.

Amongst the birds which breed here are rockhopper penguins, king shags, petrels and black- browed albatrosses. The total number of species recorded on Bird Island in November 1998 was 27, of which 25 bred or were probably breeding. Macaroni penguin, ruddy-headed goose, canary-winged finch, black-throated finch and Falkland steamer duck are present but their status is uncertain or populations are too small to qualify. The congregation of seabirds on this island exceeds 10,000 breeding pairs, making the site classifiable under the A4iii criterion.

It has been the site of at least eight known shipwrecks, including the Japanese Wiji Maru, SS Quartette, and most recently the M/V Casitas, which ran aground on the reef in 2005. The atoll is an important habitat for seabirds, marine life, and invertebrate species. Twenty-two bird species nest and breed on the islands, including twenty percent of the world's population of black-footed albatrosses. The atoll has historically been included with the rest of the Northwestern Hawaiian Islands in conservation efforts.

The superb fairy wren is socially monogamous, but 95% of its clutches contain young fathered by extra-pair males. Up to 87% of tree swallow clutches, 75% of coal tit clutches, and 70% of reed bunting clutches contain young fathered by extra-pair males. Even female waved albatrosses, which typically mate for life, are sexually promiscuous, with 17% of young fathered by extra-pair males. In many primate species, females solicit sex from males and may mate with more than one male in quick succession.

The primary food sources of the waved albatross are fish, squid, and crustaceans, as well as smaller birds. But they have also been observed to scavenge for other food sources, including the regurgitated food of other birds. When foraging, the waved albatross finds places in the ocean where prey will be near this surface; this is the most effective way for the albatross to get its food. The waved albatrosses will forage away from the place where the chicks are nesting to get food for them.

The islands have the second largest breeding colony of the northern royal albatross, and provide breeding sites for Buller's albatross, northern giant petrel, fairy prion, broad-billed prion, sooty shearwater, common diving petrel, grey-backed storm petrel, white-faced storm petrel, pitt shag, subantarctic skua, red-billed gull, and white-fronted tern. The site has been identified as an Important Bird Area by BirdLife International because it supports Buller's albatrosses and northern giant petrels. A species of stag beetle called Geodorcus sororum is endemic to the islands.

Also, the local swamp creatures were originally written as a dedicated home guard that drilled and marched incessantly. However, the writers evolved them into a volunteer group of helpful little bayou creatures. Their leader, a singing bullfrog voiced by Phil Harris, was deleted from the film. A pigeon was originally proposed to be the transportation for Bernard and Bianca, until Ollie Johnston remembered a True-Life Adventures episode that showed albatrosses and their clumsy take-offs and landings, and suggested the ungainly bird instead.

The South Georgia population is shrinking at 1.8% per year. The levels of birds at Prince Edward and the Crozet Islands seem to be stabilising although most recently there may be some shrinking of the population. The biggest threat to their survival is longline fishing; however, pollution, mainly plastics and fishing hooks, are also taking a toll. The CCAMLR has introduced measures to reduce bycatch of albatrosses around South Georgia by 99%, and other regional fishing commissions are taking similar measures to reduce fatalities.

In 1999, Okkervil River band members Jonathan Meiburg and Will Sheff founded Shearwater as an outlet for quieter songs on which they were collaborating. The band's name comes from the shearwater, a tribe of seabirds related to petrels and albatrosses. Meiburg, who holds a master's degree in geography with a focus on ornithology, picked the name mostly for the sound of the word. Shearwater's debut, The Dissolving Room, introduced Kim Burke on upright bass; shortly after, drummer and vibraphonist Thor Harris joined the band.

For almost all species the need to breed is the only reason that procellariiforms return to land at all. Some of the larger petrels have to nest on windswept locations as they require wind to take off and forage for food. Within the colonies, pairs defend usually small territories (the giant petrels and some albatrosses can have very large territories) which is the small area around either the nest or a burrow. Competition between pairs can be intense, as is competition between species, particularly for burrows.

Despite their size, there is little doubt that even the largest teratorns could fly. Visible marks of the attachments of contour feathers can be seen on Argentavis wing bones. This defies some earlier theories that modern condors, swans, and bustards represent the size limit for flying birds. The wing loading of Argentavis was relatively low for its size, a bit more than a turkey's, and if there were any significant wind present, the bird could probably get airborne merely by spreading its wings, just like modern albatrosses.

In 1908 the British government assumed ownership of the islands. In late 1947 and early 1948, South Africa, with Britain's agreement, annexed the islands and installed the meteorological station on Transvaal Cove on the north-east coast of Marion Island. The research station was soon enlarged and today studies regional meteorology and the biology of the islands, in particular the birds (penguins, petrels, albatrosses, gulls) and seals. A new research base was built from 2001 to 2011 to replace older buildings on the site.

Frozen Planet finished filming in 2010 and focused on the challenges facing polar bears and Arctic wolves in the north and Adelie penguins and wandering albatrosses in the south, although many other storylines are developed. After an introductory episode, the subsequent four episodes depict the changing seasons at the poles, before an episode focusing on mankind’s activities there. The final episode, "On Thin Ice", examines how global warming is affecting the polar regions. Filmmakers worked in new locations, including Antarctica’s active volcanoes and the Russian Arctic.

The southern giant petrel is slightly larger than the northern giant petrel, at , across the wings, and of body length.Maynard, B. J. (2003) The northern giant petrel is , across the wings and of body length. They superficially resemble the albatross, and are the only procellarids that can equal them in size. They can be separated from the albatrosses by their bill; the two tube nostrils are joined together on the top of the bill, unlike on albatross, where they are separated and on the side of the bill.

Albatrosses at Midway Atoll Midway Atoll is a critical habitat in the central Pacific Ocean which includes breeding habitat for 17 seabird species. A number of native species rely on the island, which is now home to 67–70% of the world's Laysan albatross population, and 34–39% of the global population of black-footed albatross. A very small number of the very rare short-tailed albatross also have been observed. Fewer than 2,200 individuals of this species are believed to exist due to excessive feather hunting in the late nineteenth century.

Because birds fly at an angle relative to the wind during dynamic soaring, they must be able to achieve flight speeds greater than this head wind. Consequently, birds that rely on dynamic soaring tend to have high wing loadings and high aspect ratios. In other words, gliding birds have wing shapes that allow them to behave more like fixed wing aircraft and rely mostly on passive gliding. Albatrosses have the largest wingspan of any extant bird, evidence of their primary reliance on aerodynamic and slope soaring techniques to achieve their extremely long migration patterns.

John Douglas Gibson ( – 21 May 1984) was a notable Australian amateur ornithologist who became an internationally respected expert on the Diomedeidae or albatross family. Gibson lived in Thirroul, New South Wales all his life, and worked at the nearby Port Kembla steelworks. Doug Gibson's interest in ornithology soon focused on seabirds, and from 1953 he was involved in banding at the seabird colonies at the Five Islands Nature Reserve. This led to experiments with banding albatrosses and the first successful program of banding them away from their breeding sites.

For instance, a bird with a completely brown back would receive a score of 1 for the back, while a bird with an all-white back would be scored as a 6. The index was later expanded by Pierre Jouventin and colleagues to cover the more complex patterning of the Amsterdam albatross, adding belly and tibial feather colouration. This system for categorising the wide and complex variation in appearance of great albatrosses has been instrumental in the discovery of several genetically isolated populations and consequent description of new taxa, and has made field identification easier.

Laysan albatross with chick on Midway Wisdom with her chick, in March 2011 The Laysan albatross is normally a silent bird, but on occasion may be observed emitting long "moo"-ing sounds, descending whinnies, or rattles. Female Laysan albatrosses may bond for life and cooperatively raise their young. A female Laysan albatross named Wisdom is the oldest known wild bird in the United States or the Northern Hemisphere. Wisdom was banded by a U.S. Geological Survey researcher in 1956, and in December 2016, she was seen rearing a new chick on Midway Atoll.

Laysan albatrosses are colonial, nesting on scattered small islands and atolls, often in huge numbers, and building different styles of nests depending on the surroundings, ranging from simple scoops in the sand to nests using vegetation. They have a protracted breeding cycle, and breed annually, although some birds skip years. Juvenile birds return to the colony three years after fledging, but do not mate for the first time until seven or eight years old. During these four or five years, they form pair bonds with a mate that they will keep for life.

The final US Navy HU-16 flight was made 13 August 1976 when an Albatross was delivered to the National Museum of Naval Aviation at NAS Pensacola, Florida. The final USCG HU-16 flight was at CGAS Cape Cod in March 1983, when the aircraft type was retired by the USCG. The Albatross continued to be used in the military service of other countries, the last being retired by the Hellenic Navy (Greece) in 1995. The Royal Canadian Air Force operated Grumman Albatrosses with the designation "CSR-110".

The Road to Samarcand and Aubrey-Maturin series can also be compared with respect to O'Brian's inclusion of animals. The certain horses associated with Mongols are described, as are one- and two-humped camels, and there are numerous references to yaks. The frequent mention of tiger-sharks and albatrosses in the nautical series echoes incidents aboard the Wanderer. Finally, the relationship between Derrick and the dog he discovers, rescues and names Chang, is thoughtfully developed in the same way that human/animal relationships with dogs, cats and horses are developed throughout the Aubrey- Maturin series.

Two birds squabbling over food near Kaikoura, New Zealand, with a Cape petrel behind them The albatrosses feed pelagically on fish, cephalopods and crustaceans. They feed on the sea surface or just below it, or make shallow dives from heights of 2–5 m. Flying within 15 m of the sea surface they use the updraft from wave fronts for lift. In this way they cover long distances to search for food and often follow fishing boats to squabble for offal with other seabirds and dive for baits.

Sea and desert birds have been found to have a salt gland near the nostrils which concentrates brine, later to be "sneezed" out to the sea, in effect allowing these birds to drink seawater without the need to find freshwater resources. It also enables the seabirds to remove the excess salt entering the body when eating, swimming or diving in the sea for food. The kidney cannot remove these quantities and concentrations of salt. The salt secreting gland has been found in seabirds like pelicans, petrels, albatrosses, gulls, and terns.

However, other sources claim a mean species body mass of for the Andean condor. The Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more. The mean wingspan is around and the wings have the largest surface area of any extant bird. Among living bird species, only the great albatrosses and the two largest species of pelican exceed the Andean condor in average and maximal wingspan.

The Gossamer Albatross II at the Museum of Flight in Seattle MacCready's team built two Albatrosses; the back-up plane was jointly tested as part of the NASA Langley/Dryden flight research program in 1980 and was also flown inside the Houston Astrodome, the first ever controlled indoor flight by a human-powered aircraft. The Gossamer Albatross II is currently on display at the Museum of Flight in Seattle, Washington. Alistair Cooke devoted some of his Letter From America broadcast of 15/17 Jun 1979 to Allen's achievement.

On the Jane Guy, Pym and Peters become part of the crew and join the ship on its expedition to hunt sea calves and seals for fur, and to explore the southern oceans. Pym studies the islands around the Cape of Good Hope, becoming interested in the social structures of penguins, albatrosses, and other sea birds. Upon his urging, the captain agrees to sail farther south towards the unexplored Antarctic regions. The ship crosses an ice barrier and arrives in open sea, close to the South Pole, albeit with a mild climate.

This has caused steep declines in some species, as procellariiforms are extremely slow breeders and cannot replace their numbers fast enough. Losses of albatrosses and petrels in the Southern Ocean were estimated at between 1 percent and 16 percent per year, which these species cannot sustain for long. Exotic species introduced to the remote breeding colonies threaten all types of procellariiform. These principally take the form of predators; most albatross and petrel species are clumsy on land and unable to defend themselves from mammals such as rats, feral cats and pigs.

An accompanying music video was released on 19 December 2019, following Blake's performance of the song on The Tonight Show Starring Jimmy Fallon. It was edited by Matt Meech, who also edited the documentary series Planet Earth II. The video features nature documentary footage of macaroni penguins and albatrosses as a courtesy of BBC Earth. The footage was shot on Snares Islands / Tini Heke, New Zealand. The creative process of the video started when Blake contacted Meech through his website in August 2019, asking if Meech had appropriate footage in his archive.

The Florida scrub jay has a complex system of raising young known as cooperative breeding, where young stay on as helpers at the nest of their parents. Such behaviour is exhibited on a larger scale by elephants, where all females take an interest in raising a single calf. A chimpanzee's childhood is socially complicated, as an individual must learn how to behave towards others, as well as master the use of tools. Albatrosses must be accomplished fliers as soon as possible — chicks are shown being hunted by tiger sharks.

They form large breeding colonies, where the males fight fierce battles to gain and retain permanent access to a great number of females and mate with them as soon as they are receptive again. Millions of macaroni penguins occupy huge territories on the islands to breed, as do thousands of albatrosses. The Antarctic peninsula is one of the few regions of the continent inhabited by animals, even in summer. Gentoo penguins build their nests on bare rock and humpback whales seek krill along the coast, while Adelie penguins nest even further south.

A man, played by John Cleese, is dressed as an ice-cream girl in a cinema, although instead of the regular cinema snacks she is selling a dead albatross which is tied to a hawker tray around his neck. A man (Terry Jones) approaches her and asks for two choc ices. The girl aggressively makes clear she only sells an albatross and continues shouting to draw attention to her merchandise, while the potential customer keeps asking questions about the product, like "What flavour is it?" and "Do you get wafers with it?". Finally the man buys two albatrosses for nine pence each.

Antarctic krill is the keystone species of the Antarctic ecosystem beyond the coastal shelf, and provides an important food source for whales, seals, leopard seals, fur seals, crabeater seals, squid, icefish, penguins, albatrosses and many other species of birds. Crabeater seals have even developed special teeth as an adaptation to catch this abundant food source: its unusual multilobed teeth enable this species to sieve krill from the water. Its dentition looks like a perfect strainer, but how it operates in detail is still unknown. Crabeaters are the most abundant seal in the world; 98% of their diet is made up of E. superba.

Northern royal albatross chick at Taiaroa Head There may also be seen a number of dusky dolphins, orcas and migratory large whales such as southern rights and humpbacks. Their sightings in these areas are on the increase and Taiaroa Head may be one of the best vantage points along the Otago coast. The part of Taiaroa Head where northern royal albatrosses breed is managed by the NZ Department of Conservation as a nature reserve with restricted entry. On adjacent land the Otago Peninsula Trust manage a visitor centre and run guided tours into the Nature Reserve.

The stated aim of the authors is to enable seabirds found in Australian waters to be correctly identified and to record the known facts of their habits. Seabirds covered include the penguins, albatrosses and other petrels, tropicbirds, frigatebirds, gannets, cormorants, pelicans, skuas, gulls and terns, 104 species in all. With regard to the layout and content of the book the authors say: > ”This book consists of two main parts. In the first we attempt a general > account of Australia’s sea-bird fauna, its environment in the past and > today, its distribution and the categories of birds found there.

This led in turn to the formation of the New South Wales Albatross Study Group. With others in the group he devised the Gibson Plumage Index, which is named after him, as an aid to categorising and identifying the various great albatrosses. He is also commemorated in the name of Gibson's albatross, a subspecies of the wandering albatross Diomedea exulans, though sometimes treated as a full species, Diomedea gibsoni. Gibson was a member of the Royal Australasian Ornithologists Union (RAOU) for 35 years, and he contributed many papers to its journal, the Emu, and other journals.

Tagging of Pacific Predators (TOPP) began in 2000 as one of many projects formed by Census of Marine Life, an organization whose goal is to help understand and explain the diversity and abundances of the ocean in the past, present, and future. After they were formed, TOPP began by building a coalition of researchers from all over the world to find and study predators of the Pacific Ocean. Since then, they have satellite-tagged 22 different species and more than 2,000 animals. These animals include elephant seals, great white sharks, leatherback turtles, squid, albatrosses, and more.

King penguins, chinstrap penguins, and gentoo penguins also breed in the Antarctic. The Antarctic fur seal was very heavily hunted in the 18th and 19th centuries for its pelt by sealers from the United States and the United Kingdom. The Weddell seal, a "true seal", is named after Sir James Weddell, commander of British sealing expeditions in the Weddell Sea. Antarctic krill, which congregates in large schools, is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, squid, icefish, penguins, albatrosses and many other birds.

Many aquatic molluscs are present in Antarctica. Bivalves such as Adamussium colbecki move around on the seafloor, while others such as Laternula elliptica live in burrows filtering the water above. There are around 70 cephalopod species in the Southern Ocean, the largest of which is the colossal squid (Mesonychoteuthis hamiltoni), which at up to is among the largest invertebrate in the world. Squid makes up most of the diet of some animals, such as grey- headed albatrosses and sperm whales, and the warty squid (Moroteuthis ingens) is one of the subantarctic's most preyed upon species by vertebrates.

Its name commemorates French explorer Jean-François de La Pérouse, who nearly lost two frigates when attempting to navigate the shoals. It consists of a long crescent-shaped reef, twelve sandbars, and the high La Perouse Pinnacle, the only remnant of its volcanic origins. The total land area of the islets is .

Albatrosses also produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights. While not all scientists believe it is a full species with some retaining it as a subspecies of the wandering albatross, a 2004 study of the mitochondrial DNA of the wandering albatross species complexBurg & Croxall (2004) supported the split. Other studies have shown it to be the most genetically distinct member of the wandering albatross superspecies.

One Arctic tern, ringed (banded) as a chick on the Farne Islands off the British east coast, reached Melbourne, Australia in just three months from fledging, a sea journey of over . Many tubenosed birds breed in the southern hemisphere and migrate north in the southern winter. The most pelagic species, mainly in the 'tubenose' order Procellariiformes, are great wanderers, and the albatrosses of the southern oceans may circle the globe as they ride the "roaring forties" outside the breeding season. The tubenoses spread widely over large areas of open ocean, but congregate when food becomes available.

The lift from wings is proportional to their area, so the heavier the animal or aircraft the bigger that area must be. The area is the product of the span times the width (mean chord) of the wing, so either a long, narrow wing or a shorter, broader wing will support the same mass. For efficient steady flight, the ratio of span to chord, the aspect ratio, should be as high as possible (the constraints are usually structural) because this lowers the lift-induced drag associated with the inevitable wingtip vortices. Long-ranging birds, like albatrosses, and most commercial aircraft maximize aspect ratio.

The Sandy Point plantation consists mainly of introduced Monterey pines, a species of tree native to coastal California which is known for its versatile, fast-growing, medium-density softwood. The indigenous Island Cape Myrtle is also present, along with pussy willow, grey poplar and various Eucalyptus species. The impact of invasive trees on Tristan's ecology is potentially large, with the Monterey pine being notably successful in extending its range. There have been efforts to eradicate invasive loganberry from Sandy Point, where it formed a dense undergrowth in the plantation making the area unsuitable for nesting albatrosses and Atlantic petrels.

Penguin colony in Anchorage Bay The flora of the islands has been recorded in detail, and includes megaherbs. The islands are also home to numerous bird species including the endemic Antipodes snipe, Antipodes parakeet, Reischek's parakeet, as well as several albatrosses, petrels and penguins, including half of the world population of the erect- crested penguin. Original population of fur seals seems to be regionally extinct or in serious peril where "Upland Seals" once found on Antipodes and Macquarie Island have been claimed as a distinct subspecies with thicker furs by scientists although it is unclear whether these seals were genetically distinct.

The majority of the fulmarine petrels, along with the prions, are confined to the Southern Hemisphere. The storm petrels are almost as widespread as the procellariids, and fall into two distinct subfamilies; the Oceanitinae have a mostly Southern Hemisphere distribution and the Hydrobatinae are found mostly in the Northern Hemisphere. Amongst the albatrosses the majority of the family is restricted to the Southern Hemisphere, feeding and nesting in cool temperate areas, although one genus, Phoebastria, ranges across the north Pacific. The family is absent from the north Atlantic, although fossil records indicate they bred there once.

After hatching, the incubating adult remains with the chick for a number of days, a period known as the guard phase. In the case of most burrow-nesting species, this is only until the chick is able to thermoregulate, usually two or three days. Diving-petrel chicks take longer to thermoregulate and have a longer guard phase than other burrow nesters. However, surface-nesting species, which have to deal with a greater range of weather and to contend with predators like skuas and frigatebirds, consequently have a longer guard phase (as long as two weeks in procellariids and three weeks in albatrosses).

Fowke noted that at that time there was no taboo against killing albatrosses, and this was something invented by Coleridge when he wrote of the incident. Sailors sometimes baited them with food, though the oily taste of their flesh was not greatly liked. A biographer of Rogers, Bryan Little, suggested that the harsh treatment of Hatley by the Spanish in Lima may have contributed to the "melancholy fits" during which he shot the albatross. The winds did not calm, but the ship was able to round Cape Horn, battling northward along the coast of Chile, through stormy weather.

Marion, p. 19. The squadron's Boeing SB-17 Dumbos and SC-47 Skytrains were used in the search role, with the C-47 "Gooneybirds" being commandeered on occasion to fly critical supply missions. Early in the war, both these planes began to be replaced by SB-29 Superdumbos. When the war began, Air Rescue Service's newest plane, the Grumman SA-16 Albatross amphibian, was not on the strength of any unit in the Pacific. To remedy this, a detachment of four Albatrosses from the 5th Rescue Squadron at Lowry Air Force Base, Colorado was dispatched in July 1950 to augment the 3rd Squadron.

In the mid-1990s, Shirihai turned his attention to oceanic birds and marine mammals, particularly those of the Southern Hemisphere. He published The Complete Guide to Antarctic Wildlife, and commenced a 10-year project to produce the Photographic Handbook of Birds of the World. Shirihai has visited almost every subantarctic island and the breeding grounds of all forms of albatrosses, with special interest in plumage variation and identification. In 2008, he confirmed the continuing existence of the mysterious Beck's petrel (Pseudobulweria becki), known until then from 2 specimens collected in the 1920s and a handful of tentative sight records.

The importance and sensitivity of smell varies among different organisms; most mammals have a good sense of smell, whereas most birds do not, except the tubenoses (e.g., petrels and albatrosses), certain species of vultures, and the kiwis. Although, recent analysis of the chemical composition of volatile organic compounds (VOCs) from King Penguin feathers suggest that VOCs may provide olfactory cues, used by the penguins to locate their colony and recognise individuals. Among mammals, it is well developed in the carnivores and ungulates, which must always be aware of each other, and in those that smell for their food, such as moles.

Sooty albatrosses nest on islands in the South Atlantic (Tristan da Cunha and Gough Island) and islands in the South Indian Ocean (the Crozet Islands to Kerguelen Island). At sea they forage from South America to Australia, with a few records of birds reaching New Zealand. The light-mantled albatross has a wider distribution, nesting on South Georgia in the Atlantic, many of the same islands in the Indian Ocean, Macquarie Island and New Zealand's subantarctic islands. At sea it forages further south than the sooty to Antarctica, and around the Southern Ocean as far north as Chile, Tasmania and South Africa.

While some species use the leg over the lowered wing to reach the head, others extend the leg more directly between the wing and the body. In general, these activities take place while the bird is either perched, on the ground, or swimming, but some of the more aerial species (including swallows, terns and albatrosses) preen on the wing. Many birds have a slight overhang at the tip of their upper mandible. Experiments suggest that this allows birds to apply shearing forces that kill the flattened feather lice; the removal of the bill tip caused an increase in feather lice due to ineffective preening.

Northern royal albatrosses are listed as an endangered species by the IUCN, and they have an occurrence range of , with a breeding range of . 6,500 to 7,000 pairs breed on the Chatham Islands annually along with 60 pairs at Taiaroa Head, for an estimated total of 20,000 birds, although this is a 2012 estimate. In 1985 their main breeding grounds on the Chatham Islands was badly damaged by a series of intense storms and the resulting lack of nesting material has lowered their breeding success. Chicks and eggs of birds breeding on the South Island have also been preyed upon by introduced species, such as cats, bottle flies, and stoats.

Restoration O. toliapica is among the smallest pseudotooth birds known to date - but this still means that to would have rivalled, if not exceeded, most living albatrosses in wingspan and the brown pelican (Pelecanus occidentalis) in bulk. In life, its head (including the beak) would have been 20–25 cm (8–10 in) long. Unlike in most other pseudotooth birds, its "teeth" are slanted forwards.Hopson (1964), González-Barba et al. (2002), Mayr (2008, 2009: pp.57,59) Like those of its relatives, the thin-walled bones of Odontopteryx broke easily and thus very few fossils - though still far more than of the average pseudotooth bird genus - are decently preserved.

The bay, with part of the south-western slopes of Mont Ross, has been identified as a 20 km2 Important Bird Area (IBA) by BirdLife International because of its breeding seabirds. Of the penguins, there are some 21,500 pairs of kings, 500 pairs of gentoos, 6000 pairs of macaronis and 4000 pairs of eastern rockhoppers. Other birds nesting in the IBA include a few pairs of wandering albatrosses, Antarctic and slender-billed prions, white-chinned, northern giant and common diving petrels, Kerguelen shags, Kerguelen terns, black-faced sheathbills and Eaton's pintails. Antarctic fur seals and southern elephant seals also breed on the shores of the bay.

Chick, Midway Atoll Laysan albatross rookery on Midway Atoll Lead poisoning is killing thousands of Laysan albatrosses each year on Midway Atoll, part of the Papahānaumokuākea Marine National Monument. The Laysan albatross has been globally listed as vulnerable to extinction by the World Conservation Union and is a special trust species on the Midway Atoll National Wildlife Refuge in the recently established national monument. "Laysan chicks raised in nests close to 90 buildings left behind by the Navy are ingesting lead-based paint chips. This is causing shockingly high lead concentrations in their blood, leading to severe neurological disorders, and eventual death," said George Fenwick, president of American Bird Conservancy.

Birds have acute eyesight—raptors (birds of prey) have vision eight times sharper than humans—thanks to higher densities of photoreceptors in the retina (up to 1,000,000 per square mm in Buteos, compared to 200,000 for humans), a high number of neurons in the optic nerves, a second set of eye muscles not found in other animals, and, in some cases, an indented fovea which magnifies the central part of the visual field. Many species, including hummingbirds and albatrosses, have two foveas in each eye. Many birds can detect polarised light. The avian ear is adapted to pick up on slight and rapid changes of pitch found in bird song.

It is less clear what to make of the Southern Hemisphere pseudotooth birds fossils, none of which are complete enough for more than the most tentative identification. Many seabirds of our time, such as albatrosses and other Procellariiformes, show a phylogenetic division between Northern and Southern Hemisphere lineages, separated by the Equatorial currents. Whether this also held true in the warmer climate of the Miocene is not known, but the general phylogenetic patterns found in Procellariiformes suggests that the north–south division is rather ancient and evolved even before the Miocene.Olson (1985: pp.197–199), Goedert (1989), Nunn & Stanley (1998), González-Barba et al.

These birds nest on Midway Atoll and are being fed plastic by their parents, who find floating plastic in the middle of the ocean and mistake it for food. This is a part of an ongoing arts and media project called Midway Journey, which has its own website. In relation to the Midway photographs, Jordan created another project that was going to be a documentary.

During the 19th century nesting albatrosses were subject to sporadic, uncontrolled egg harvesting by sealers and other visitors to the Aucklands. Although this has ceased, from the mid 20th century onwards the population has become increasingly threatened through bycatch mortality in the Southern Ocean longline fishery by the foraging birds being hooked, entangled and drowned. Other threats include starvation through consumption of floating plastic debris, and potentially, at their nesting sites, by human disturbance, the accidental introduction of rodents and other exotic predators, and by habitat alteration caused by climate change. Gibson's albatross is listed as vulnerable under Australia's Environment Protection and Biodiversity Conservation Act 1999.

There is also a large and readily observed colony of southern fur seals at the eastern edge of the town. At low tide, better viewing of the seals can be had as the ocean gives way to a rocky base which is easily navigable by foot for quite some distance. It is also one of the best reasonably accessible places in the world to see open ocean seabirds such as albatrosses, petrels and shearwaters, including the Hutton's shearwater which nests high in Kaikōura mountains. A strategic plan for the future of the Kaikoura Coast is being developed by Te Korowai o te Tai o Marokura, the Kaikōura Coastal Guardians.

Birds in this area include various species of albatrosses and petrels that feed on the banks and waters of Burdwood Bank: black-browed albatross, grey-headed albatross, wandering albatross, Tristan albatross, northern giant petrel, southern giant petrel, chin petrel White, as well as penguins: Magellanic penguin, rockhopper penguin, gentoo penguin, king penguin, and pinnipeds such as sea lions and elephant seals. The Burdwood Bank generates conditions that favor fishing productivity in the area. In the waters surrounding the bank are breeding and spawning sites for many fish species. The species community on the bank is dominated by the small nonotenids Patagonotothen guntheri and Patagonian toothfish.

The procellariiforms are for the most part exclusively marine foragers; the only exception to this rule are the two species of giant petrel, which regularly feed on carrion or other seabirds while on land. While some other species of fulmarine and Procellaria petrels also take carrion, the diet of most species of albatrosses and petrels is dominated by fish, squid, krill and other marine zooplankton. The importance of these food sources varies from species to species and family to family. For example, of the two albatross species found in Hawaii, the black-footed albatross takes mostly fish, while the Laysan feeds mainly on squid.

When the female returns and lays, incubation is shared between the sexes, with the male taking the first incubation stint and the female returning to sea. The duration of individual stints varies from just a few days to as much as several weeks, during which the incubating bird can lose a considerable amount of weight.Warham, J. (1990) The Petrels – Their Ecology and Breeding Systems London: Academic Press. The incubation period varies from species to species, around 40 days for the smallest storm-petrels but longer for the largest species; for albatrosses it can span 70 to 80 days, which is the longest incubation period of any bird.

In that respect, the specializations for dynamic soaring restricted the number of possible nesting sites for the birds, but on the other hand upland on islands or in coastal ranges could have provided breeding grounds for Pelagornithidae that was inaccessible for pinnipeds; just as many albatrosses today nest in the uplands of islands (e.g. the Galápagos or Torishima). The bony-toothed birds probably required strong updrafts for takeoff and would have preferred higher sites anyway for this reason, rendering competition with pinniped rookeries quite minimal. As regards breeding grounds, giant eggshell fragments from the Famara mountains on Lanzarote, Canary Islands, were tentatively attributed to Late Miocene pseudotooth birds.

A hole score of three strokes fewer than par (three under par, −3) is known as an albatross (the albatross being one of the largest birds); also called a double eagle in the US, e.g. 2 strokes to complete a par 5 hole. It is an extremely rare score and occurs most commonly on par-fives with a strong drive and a holed approach shot. Holes-in-one on par-four holes (generally short ones) are also albatrosses. The first famous albatross was made by Gene Sarazen in 1935 on the 15th hole at Augusta National Golf Club during the final round of the Masters Tournament.

A group of Laysan albatrosses resting beneath the canopy of a fig, a common shade tree in many parts of the world. A shade tree is a large tree whose primary role is to provide shade in the surrounding environment due to its spreading canopy and crown, where it may give shelter from sunlight in the heat of the summer for people who seek recreational needs in urban parks and house yards, and thus, also protecting them from the sun's harmful UV rays and sunburns. Therefore, some shade trees may be grown specifically for the comfort of the population due to their convenient shelter. Furthermore, shade trees are also effective in reducing the energy used in cooling homes.

A USAF SA-16A during the Korean War. The majority of Albatrosses were used by the U.S. Air Force (USAF), primarily in the search and rescue mission role (SAR), and initially designated as SA-16. The USAF used the SA-16 extensively in Korea for combat rescue, where it gained a reputation as a rugged and seaworthy craft. Later, the redesignated HU-16B (long-wing variant) Albatross was used by the USAF's Aerospace Rescue and Recovery Service and saw extensive combat service during the Vietnam War. In addition a small number of Air National Guard air commando groups were equipped with HU-16s for covert infiltration and extraction of special forces from 1956 to 1971.

Like in any other highly essential system in biology, mammalian sperm guidance is expected to involve redundancy. Indeed, at least three guidance mechanisms are likely to act in the female genital tract, two active mechanisms — chemotaxis and thermotaxis, and a passive mechanism — rheotaxis. When one of these mechanisms is not functional for any reason, guidance is not expected to be lost and the cells should still be able to navigate to the oocyte. This resembles guidance of migrating birds, where the birds’ navigation is unaffected when one of the guidance mechanisms is not functional.Mouritsen, H., Huyvaert, K.P., Frost, B.J., Anderson, D.J. (2003) Waved albatrosses can navigate with strong magnets attached to their head.

198) The bony-toothed or pseudotooth birds were initially believed to be related to albatrosses in the Procellariiformes, but actually they seem to be rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty. Also, their internal taxonomy is not well-resolved. An earlier-described pseudotooth bird, Cyphornis magnus from Vancouver Island (Canada), was believed to be of Eocene age but is nowadays assumed to have lived about twenty million years ago in the Early Miocene, not too long before the Clarendonian (Middle/Late Miocene) O. orri. It may be that Osteodontornis is a junior synonym of Cyphornis.

The flag of Tristan da Cunha The flag of Tristan da Cunha was adopted on 20 October 2002, in a proclamation made by the Governor of Saint Helena under a Royal Warrant granted by Queen Elizabeth II. Prior to this, as a dependency of Saint Helena, Tristan da Cunha used the flag of Saint Helena for official purposes. The flag is a blue ensign design, defaced with the coat of arms of Tristan da Cunha — a Tristan longboat above a Naval Crown, with a central shield decorated with four yellow-nosed albatrosses and flanked by two Tristan rock lobsters. Below this is a scroll with the territory's motto, Our faith is our strength.

Wandering albatross at South Georgia During the first 13 months of operations the group caught and banded 197 "wandering" and two black-browed albatrosses, 63% of which were caught at Bellambi. The group's first international recovery was of an adult male Wanderer, banded at Bellambi on 23 August 1958, which was present on Bird Island, South Georgia, in the South Atlantic Ocean, from 29 December 1958 to 6 March 1959. In 1959 the group caught and banded 551 Wanderers, 21 of which were retraps from the previous year, as well as a bird banded in South Georgia. By the end of the 1962 winter banding season, a total of 1238 Wanderers had been banded.

The last crew of castaways to obtain relief from the depots were the 22 crew members from the French barque President Félix Faure that was wrecked off the North Cape of the main island of the Antipodes Islands on 13 March 1908. Their lifeboat was broken up by the waves and all their stores were lost, but the entire crew made it ashore not far from one of the depots. After they had used up the depot's supplies, they hunted albatrosses, penguins and a calf - the sole remnant of the cattle that had been set ashore earlier by the . They were rescued by the warship , that was alerted by the smoke from their fires.

The Dalmatian pelican (Pelecanus crispus) is the largest member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans that rival that of the great albatrosses, and their flocks fly in graceful synchrony. With a range spanning across much of Central Eurasia, from the Mediterranean in the West to the Taiwan Strait in the East, and from the Persian Gulf in the South to Siberia in the North, it is a short-to-medium- distance migrant between breeding and overwintering areas. No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, P. c.

Adult female Aedes taeniorhynchus Ae. taeniorhynchus eggs can mature both autogenously and anautogenously, with autogenous eggs feeding on sugar and anautogenous eggs requiring a blood meal. These food sources promote maturation by producing hormones from the corpora allata (CA) and medial neurosecretory cell perikarya (MNCA), of which only MNCA hormone release is responsible for anautogenous maturation. Larval dependence on a blood meal can be influenced to make mosquitoes less autogenous, by not allowing females to feed on sugar and imposing other dietary changes. Aedes taeniorhynchus is an ectoparasite of waved albatrosses Adult mosquitoes feed on a combination diet of blood and sugar, with the optimal diet consisting of sugar for males and both blood and sugar for females.

Most of the common names refer to these birds' most notable trait: tooth-like points on their beak's edges, which, unlike true teeth, contained Volkmann's canals and were outgrowths of the premaxillary and mandibular bones. Even "small" species of pseudotooth birds were the size of albatrosses; the largest ones had wingspans estimated at 5–6 metres (15–20 ft) and were among the largest flying birds ever to live. They were the dominant seabirds of most oceans throughout most of the Cenozoic, and modern humans apparently missed encountering them only by a tiny measure of evolutionary time: the last known pelagornithids were contemporaries of Homo habilis and the beginning of the history of technology.Hopson (1964), Olson (1985: pp.

Warheit (1992, 2001), Olson & Rasmussen (2001), Geraads (2006), Chávez et al. (2007), Mayr (2009: pp. 217–218), GG [2009], Mlíkovský (2009) In the late Neogene, ancestral bull sharks (Carcharhinus leucas) may well have eaten pseudotooth birds on occasion offshore today's North Carolina Irrespective of the cause of their ultimate extinction, during the long time of their existence the pseudotooth birds furnished prey for large predators themselves. Few if any birds that coexisted with them were large enough to harm them while airborne; as evidenced by the Early Eocene Limnofregata, the frigatebirds coevolved with the Pelagornithidae and may well have harassed any of the small species for food on occasion, as they today harass albatrosses.

During hauling operations, blue dyed baited and tori lines were found to be equally effective mitigation strategies, followed by the towed buoy. Retaining offal on the vessel during the haul increased seabird interactions. The National Marine Fisheries Service Pacific Islands Fisheries Science Center (NMFS PIFSC) also tested tori lines, blue dyed bait and weighted hooks in 1999, They found that baits dyed blue and baits with additional weight reduced the number of interactions with both black-footed and Laysan albatross. Tori lines reduced contact between baits and albatrosses by 70% The WPRFMC's plan for implementing seabird mitigation measures was for an Fishery Management Plan(FMP) amendment where fishermen could choose the measures from a selected list of proven mitigation methods.

These aircraft are operated under either Experimental-Exhibition or Restricted category and cannot be used for commercial operations, except under very limited conditions. In the early 1980s Chalk's International Airlines owned by Merv Griffin's Resorts International had 13 Albatrosses converted to Standard category as G-111s. This made them eligible to be used in scheduled airline operations. These aircraft had extensive modification from the standard military configuration, including rebuilt wings with titanium wing spar caps, additional doors and modifications to existing doors and hatches, stainless steel engine oil tanks, dual engine fire extinguishing systems on each engine and propeller auto feather systems installed. The G-111s were operated for only a few years and then put in storage in Arizona.

Catching albatrosses was only possible because, in light winds and while the birds were burdened with food, it was very difficult for them to take off from the water. Experiments began with the use of a metal triangle on a float; it was baited with cuttlefish meat to catch the albatross attempting to grasp the bait by the nail, or hooked tip of its upper mandible, and so draw it into a boat where it could be measured and banded. However, this method was slow and uncertain and it was replaced by the use of a hand- held hoop net, 1.35 m in diameter, which could be thrown over the bird as the boat approached it downwind while it struggled to become airborne.

The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. Associated with the Circumpolar Current is the Antarctic Convergence, where the cold Antarctic waters meet the warmer waters of the subantarctic, creating a zone of upwelling nutrients. These nurture high levels of phytoplankton with associated copepods and krill, and resultant foodchains supporting fish, whales, seals, penguins, albatrosses, and a wealth of other species. The ACC has been known to sailors for centuries; it greatly speeds up any travel from west to east, but makes sailing extremely difficult from east to west, although this is mostly due to the prevailing westerly winds.

Antarctica is also home to a diversity of animal life, including penguins, seals, and whales. Several Antarctic island groups are considered part of the Antarctic realm, including South Georgia and the South Sandwich Islands, South Orkney Islands, the South Shetland Islands, Bouvet Island, the Crozet Islands, Prince Edward Islands, Heard Island, the Kerguelen Islands, and the McDonald Islands. These islands have a somewhat milder climate than Antarctica proper, and support a greater diversity of tundra plants, although they are all too windy and cold to support trees. Antarctic krill is the keystone species of the ecosystem of the Southern Ocean, and is an important food organism for whales, seals, leopard seals, fur seals, crabeater seals, squid, icefish, penguins, albatrosses and many other birds.

Brooke, 2004. p. 126 The albatrosses in general feed on fish, squid and krill. Among the procellariids, the prions concentrate on small crustacea, the fulmarine petrels take fish and krill but little squid, while the Procellaria petrels consume mainly squid. The storm petrels take small droplets of oil from the surface of the water, as well as small crustaceans and fish.Brooke, 2004. p. 127 Petrels obtain food by snatching prey while swimming on the surface, snatching prey from the wing or diving down under the water to pursue prey. Dipping down from flight is most commonly used by the gadfly petrels and the storm petrels. There have been records of wedge-tailed shearwaters snatching flying fish from the air, but as a rule this technique is rare.

Cylindrical pottery found at the site dates it to 4,500-6,000 years ago which corresponds to early to middle Jōmon period. Around this time, the surrounding area was submerged by the expanding brackish water of ancient Lake Jūsan due to a rise in sea levels. The midden is almost exclusively made of Yamato-shijimi clams which were harvested from the brackish water; however, other shells, as well as the bones of fish including carp and Japanese sea bass and the bones of birds such as geese, ducks and short-tailed albatrosses have been unearthed. In addition, bone implements made of the bones of large mammals such as whales and dolphins as well as human bones have also been unearthed at the site.

Marine debris strewn over the beaches of the South Atlantic Inaccessible Island Endangered marine species include the manatee, seals, sea lions, turtles, and whales. Drift net fishing can kill dolphins, albatrosses and other seabirds (petrels, auks), hastening the fish stock decline and contributing to international disputes. Municipal pollution comes from the eastern United States, southern Brazil, and eastern Argentina; oil pollution in the Caribbean Sea, Gulf of Mexico, Lake Maracaibo, Mediterranean Sea, and North Sea; and industrial waste and municipal sewage pollution in the Baltic Sea, North Sea, and Mediterranean Sea. North Atlantic hurricane activity has increased over past decades because of increased sea surface temperature (SST) at tropical latitudes, changes that can be attributed to either the natural Atlantic Multidecadal Oscillation (AMO) or to anthropogenic climate change.

The various species within the order have a variety of migration strategies. Some species undertake regular trans-equatorial migrations, such as the sooty shearwater which annually migrates from its breeding grounds in New Zealand and Chile to the North Pacific off Japan, Alaska and California, an annual round trip of , the longest measured annual migration of any bird. A number of other petrel species undertake trans- equatorial migrations, including the Wilson's storm petrel and the Providence petrel, but no albatrosses cross the equator, as they rely on wind assisted flight. There are other long-distance migrants within the order; Swinhoe's storm petrels breed in the western Pacific and migrates to the western Indian Ocean, and Bonin petrels nesting in Hawaii migrate to the coast of Japan during the non-breeding season.

The Flag of Tristan da Cunha The Flag of the Administrator of Tristan da Cunha The flag of Tristan da Cunha was adopted on October 20, 2002, in a proclamation made by the Governor of Saint Helena under a Royal Warrant granted by Queen Elizabeth II. Prior to this, as a dependency of Saint Helena, Tristan da Cunha used the flag of Saint Helena for official purposes. The flag is a blue ensign design, defaced with the coat of arms of Tristan da Cunha — a Tristan longboat above a Naval Crown, with a central shield decorated with four yellow-nosed albatrosses and flanked by two Tristan rock lobsters. Below this is a scroll with the territory's motto, Our faith is our strength. The designer is the prominent vexillologist Graham Bartram.

In addition, whatever caused the Middle Miocene disruption and the Messinian Salinity Crisis did affect the trophic web of Earth's oceans not insignificantly either, and the latter event led to a widespread extinction of seabirds. Together, this combination of factors led to Neogene animals finally replacing the last remnants of the Paleogene fauna in the Pliocene. In that respect, it is conspicuous that the older pseudotooth birds are typically found in the same deposits as plotopterids and penguins, while younger forms were sympatric with auks, albatrosses, penguins and Procellariidae – which, however, underwent an adaptive radiation of considerable extent coincident (and probably caused by) with the final demise of the Paleogene-type trophic web. Although the fossil record is necessarily incomplete, as it seems cormorants and seagulls were very rarely found in association with the Pelagornithidae.

The systematics of bony-toothed birds are subject of considerable debate. Initially, they were allied with the (then- paraphyletic) "Pelecaniformes" (pelicans and presumed allies, such as gannets and frigatebirds) and the Procellariiformes (tube-nosed seabirds like albatrosses and petrels), because of their similar general anatomy. Some of the first remains of the massive Dasornis were mistaken for a ratite's and later a diatryma's. They were even used to argue for a close relationship between these two groups – and indeed, the pelicans and tubenoses, as well as for example the other "Pelecaniformes" (cormorants and allies) which are preferably separated as Phalacrocoraciformes nowadays, the Ciconiiformes (storks and/or either herons and ibises or the "core" Pelecaniformes) and Gaviiformes (loons/divers) seem to make up a radiation, possibly a clade, of "higher waterbirds".

Kea (Nestor notabilis) is the world's only alpine parrot and has high intelligence and inquisitiveness The terrestrial birds, wetland birds and seabirds in New Zealand each make up about a third of the total number of species. This is in sharp contrast to the composition of the global bird species where 90% are terrestrial. When humans first arrived in New Zealand, there were at least 131 species of land, freshwater and coastal birds, and another 65 species of seabirds (gulls, albatrosses, petrels and penguins), making at least 196 native species in total, according to a 1997 report (this count may have risen since as subspecies have been reclassified as species). Of the 131 species that lived on or near land, 93 (or 71%) were endemic, and of the 65 seabirds, 22 (or 34%) were endemic, making 115 (or 59%) endemic species in total.

Born at Marton, New Zealand and educated in Wanganui, Richdale became a teacher based in Dunedin after obtaining a diploma in 1922 from Hawkesbury Agricultural College near Sydney, Australia. Richdale's main ornithological interest was in seabirds, especially penguins and petrels, and he was engaged in long-term studies of various species for most of his life. He was the driving force to gain protection for the colony of northern royal albatrosses at Taiaroa Head, Otago, after discovering the first successful fledgling there in 1938. Although his fieldwork was carried out in southern New Zealand, he spent some time studying overseas, as a Fulbright Fellow at Cornell University (1950–1951), as a Nuffield Research Fellow at the Edward Grey Institute for Bird Research (1952–1955) and, after retirement, again as a Nuffield Fellow, at the Zoological Society of London (1960–1963).

The storm petrels, Hydrobatidae, are one of the four major families of the Procellariiformes or "tubenoses", an order of seabirds that also includes the albatrosses, the Procellariidae, and the diving petrels. The family is an ancient group of small species that is thought to have diverged early from the rest of the tubenoses; the supporting fossil record is poor, with specimens from California dating back only to the Late Miocene (11.6–5.3 million years ago). The Hydrobatidae are often divided into two subfamilies, the mainly Southern Hemisphere Oceanitinae and the northern Hydrobatinae; cytochrome b DNA sequence analysis suggests that these might be full families. The European storm petrel is the only member of the genus Hydrobates, the remainder of the Hydrobatinae being placed in Oceanodroma, although the least storm petrel is sometimes separated as the sole member of Halocyptena.

Laysan and short-tailed albatrosses at Northwest Hawaiian Islands National Monument Hawaiian monk seal Spinner dolphins at Midway Atoll The Northwestern Hawaiian Islands (NWHI) were first protected on February 3, 1909, when U.S. President Theodore Roosevelt created the Hawaiian Islands Bird Reservation through , as a response to the over-harvesting of seabirds, and in recognition of the importance of the NWHI as seabird nesting sites. President Franklin D. Roosevelt converted it into the Hawaiian Islands National Wildlife Refuge in 1940. A series of incremental protections followed, leading to the establishment of Midway Atoll National Wildlife Refuge in 1988, Kure Atoll State Wildlife Sanctuary in 1993, and the NWHI Coral Reef Ecosystem Reserve in 2000.National Marine Sanctuaries Act of 2000 , which became Public Law 106-513 on November 13, 2000. President Bill Clinton established the Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve on December 4, 2000, with Executive Order 13178.

Formed from the 6167th Air Base Unit in October 1950 to operate flare aircraft, psychological operations, and behind-the-lines agent insertions and resupply drops during the war. Its designation served as a cover for its actual special operations activities Its 6167th Operations Squadron was augmented by aircrews from the Clark AB, Philippines-based 581st Air Resupply and Communications Wing (581st ARCW), a cover designation for a special operations unit. Aircraft operated were the B-26 Invader, C-46 Commando, and C-47s. Two SA-16 Albatrosses were sent to K-16 (Seoul Airport) in South Korea by the 581st ARCW to augment B Flight of the 6167th Air Base Group. In addition, four Sikorsky H-19A helicopters were also forward deployed to K-16 in support of the 2157th Air Rescue Squadron (in fact, they were colocated with the 2157th but actually supported B Flight, as did the two SA-16s).

Skeletal reconstruction of a quadrupedally launching male P. longiceps The wing shape of Pteranodon suggests that it would have flown rather like a modern-day albatross. This is based on the fact that Pteranodon had a high aspect ratio (wingspan to chord length) similar to that of the albatross — 9:1 for Pteranodon, compared to 8:1 for an albatross. Albatrosses spend long stretches of time at sea fishing, and use a flight pattern called "dynamic soaring" which exploits the vertical gradient of wind speed near the ocean surface to travel long distances without flapping, and without the aid of thermals (which do not occur over the open ocean the same way they do over land). While most of a Pteranodon flight would have depended on soaring, like long-winged seabirds, it probably required an occasional active, rapid burst of flapping, and studies of Pteranodon wing loading (the strength of the wings vs.

From the Middle Miocene or Early Pliocene of the Lee Creek Mine, some remains of pseudotooth birds which probably fell victim to sharks while feeding are known. The large members of the abundant Lee Creek Mine shark fauna that hunted near the water's surface included the broadnose sevengill shark (Notorynchus cepedianus), Carcharias sand tiger sharks, Isurus and Cosmopolitodus mako sharks, Carcharodon white sharks,The huge megalodon shark (Carcharocles megalodon) would probably have found even the largest pseudotooth bird to be not worth the effort of hunting. the snaggletooth shark Hemipristis serra, tiger sharks (Galeocerdo), Carcharhinus whaler sharks, the lemon shark (Negaprion brevirostris) and hammerhead sharks (Sphyrna), and perhaps (depending on the bird fossils' age) also Pristis sawfishes, Odontaspis sand tiger sharks, and Lamna and Parotodus benedeni mackerel sharks. It is notable that fossils of smaller diving birds – for example auks, loons and cormorants – as well as those of albatrosses are much more commonly found in those shark pellets than pseudotooth birds, supporting the assumption that the latter had quite low population densities and caught much of their food in mid-flight.

However, the wing had a senior officer serving as a liaison with the CIA. This was Lt. Colonel George Pittman, whose identity was also kept secret from those who did not have a need to know. The four Fairchild C-119 Flying Boxcar and support personnel were placed on a 90-day rotation schedule. The commander, 315th Air Division determined where the aircraft would be deployed. Two Grumman SA-16 Albatrosses were sent to K-16 (Seoul Airport) in South Korea to augment B Flight of the 6167th Air Base Group. The four Sikorsky H-19 ChickasawA helicopters were also deployed to K-16 to support the 2157th Air Rescue Squadron (in fact, they were co-located with the 2157th but actually supported B Flight, as did the two SA-16s). "34 CCRAK," (probably an entity associated with Combined Command Reconnaissance Activities, Korea) maintained Operational Control (OPCON) of these forces and employed them on incursions into North Korea, along with B Flight and Special Air Missions detachment aircraft.The Helicopter Flight and SA-16 Flight of the 581st Air Resupply Squadron received the Korean Service Steamer for their actions in Korea, but the rest of the wing did not.

Initially it was the home of the 61st Fighter Wing which included the 194th Fighter Squadron on June 25, 1948. The 61st Fighter Wing was re-designated as the 144th Fighter Bomber Wing on November 1, 1950. The wing also consisted of the 192nd Fighter Squadron at Reno, Nevada and the 191st Fighter Squadron at Salt Lake City, Utah. The North American P-51D Mustang and later the P-51H were flown from 1948 until October 31, 1954. During its early years with the P-51D/H, the unit earned prominence as one of the Air Force's most respected aerial gunnery competitors. In June 1953, while still flying the P-51, the unit qualified for the first all-jet, worldwide gunnery meet. Using borrowed F-86A Sabre jets, the 144th, which represented the Air National Guard, placed fifth in competition. This unit later relocated to Fresno Air Terminal and is now the 144th Fighter Wing of the California Air National Guard at Fresno Air National Guard Base. On April 3, 1955 the 129th Air Resupply Squadron was established at Hayward and equipped with Curtiss C-46D Commandos in the Summer 1955 supplemented by Grumman SA-16A Albatrosses in 1958.

A somewhat generic reconstruction of Osteodontornis, but unlikely to be very wrong in any major aspect regardless of these birds' actual relationships Courting wandering albatrosses (Diomedea exulans) show the typical colour pattern of seabirds Like the other more basal Anseriformes, the southern screamer (Chauna torquata) lacks the bright colours and conspicuous sexual dimorphism found in most dabbling ducks Nothing is known for sure about the colouration of these birds, as they have not left living descendants. But some inferences can be made based on their phylogeny: if they were a member of the "higher waterbird" group (see below), they most probably had a plumage similar to that depicted in the reconstruction of Osteodontornis orri – Procellariiformes and Pelecaniformes in the modern sense (or Ciconiiformes, if Pelecaniformes are merged there) have hardly any carotenoid or structural colors at all in their plumage, and generally lack even phaeomelanins. Thus, the only colours commonly found in these birds are black, white and various shades of grey. Some have patches of iridescent feathers, or brownish or reddish hues, but these are rare and limited in extent, and those species in which they are found (e.g.
