Only a minority of birds are cavity nesters that would compete for a backyard nest box.
|

A red wasp chases a brooding bluebird from the nest box, and I rub soap into the wood of the birdhouse roof.
|
|
I look around at all the ways I've tried to help — at the reusable grocery bags and the solar-field subscription, at the pollinator garden and the little meadow of wildflowers, at the lawn mower blades set high enough to harm no snakes or nesting cottontails, at the recycle bins and the worm composter, at the nest box for the bluebirds and the nest box for the house wrens and the nest box claimed this year by a red wasp — and it all strikes me as puny, laughable, at best a way to feel better about myself.
|

Then I opened the nest-box door and folded my hand around the smooth, cool shell of an Easter Egger hen's blue-green egg.
|
|
Even the chickadees, which nest early and have always liked our bluebird box, settled for the smaller nest box under the eaves near the back door.
|

Margaret Renkl Nashville — Two years ago, a day before the baby bluebirds were due to hatch, I checked the nest box just outside my office window and found a tiny hole in one of the eggs.
|
|
The pups will be gradually introduced to life outside of their "nest box,'" but for now visitors can only see them at the zoo for very brief times and under the watchful eyes of their human and meerkat parents.

|
While the bluebird was successfully repelling the flock of starlings, I later discovered, a tiny house wren was pulling all the moss and all the speckled eggs out of the nest box on the other side of the house.
|
|
But the eggs of a house wren are vulnerable to heat, and it's been unendurably hot here for days — the temperature inside a nest box mounted in a sunny clearing can easily exceed the maximum temperature for a house-wren egg to remain viable.
|
|
The rest of the starlings were unperturbed by this spectacle, but the female bluebird inside the box was drawn to the fray, peeking out of the hole of the nest box as her mate staged unceasing guerrilla raids on the intruders from a low-hanging branch in his lookout tree.
|
|
The male bluebird set up an angry clicking from his perch in a nearby maple as soon as the flock landed in our yard, and when one of them had the nerve to peer into the nest-box hole — which is, by design, too small to admit a starling — he immediately dived at the intruder's head, startling it so thoroughly that it fell to the ground before it could stop its headlong tumble and fly away.

An image from a nest box camera A nest box camera, also known as a bird box camera, is a photographic device fitted inside a nest box in order to monitor its inhabitants. Many Internet sites broadcast video streams and still images of nesting birds in real time.

|
A webcam is frequently used by enthusiasts but the quality is usually standard-definition. Wired network cameras allow the streaming of high-definition video to the internet or to internal or external storage. Some nest box cameras have microphones inside them. It is relatively easy to construct a nest box camera because it involves little more than installing a camera in a nest box, remembering only to choose or construct a nest box large enough to contain the camera, to have a box deep enough to enable proper focusing of the camera and to use a camera suitable for outdoor conditions.

Nest boxes provide direct physical access to the breeding location. In Switzerland, a research group aims to install RFID tag readers on the entrance of the nest boxes, thus allowing tracking of barn owl movements from nest box to nest box. Information about the behavior of the owls prior to breeding could be obtained using surveillance. In the United Kingdom, the "Barn Owl Nest Box Scheme" is promoted by the World Owl Trust and has many participants in local areas such as Somerset, where a webcam has been set up inside a nest box in which 7 young were reared in 2014.

The chicks and eggs of budgerigar in nest box Breeding difficulties arise for various reasons. Some chicks may die from diseases and attacks from adults. Other budgerigars (virtually always females) may fight over the nest box, attacking each other or a brood. Another problem may be the birds' beaks being under-lapped, where the lower mandible is above the upper mandible.

|
It is believed that the swallows benefit from the cooperative relationship by inheriting the nest box after the bluebird parents and fledglings have left.

|
The size of the nest box, entry hole and placement height may be chosen in consideration of certain species. Natural hollows are still generally preferred for habitat conservation.
|
|
It is typical for the male to help raise the kittens, getting in the nest box with them. If left together, the mother will often wait months to wean her kittens, even though their development is fairly rapid once they leave the nest box. Breeders expect one to two litters per year, per breeding pair. Sometimes two litters may come closely in a row, with a longer period of time before further reproduction.

|
Tans are not known for having common genetic defects. In general, most Tan babies will be born healthy. However, Tans are a very hyperactive breed and sometimes as a result they will have babies outside the nest box or have them inside the nest box but inadvertently step on the babies as they jump in and out of the box. These problems are more common with new moms and nervous and/or unsocialized rabbits.

In 1994 Dennis Money, the founder of the Rochester Peregrine Falcon Project, got permission from Kodak to install a nest box on the spire of the Kodak Office Tower. The nest box was installed as part of an effort to reintroduce peregrine falcons to eastern North America after the species was listed on the U.S. Endangered Species list.Rochester's Falcon HistoryKodak Peregrine Falcon Web Cam In 1998 a pair of peregrine falcons known to the public as Mariah & Cabot-Sirocco began nesting in the nest box. The reintroduction effort became popular over the web after Brad Carney an IT Consultant at Eastman Kodak coordinated an effort to install web cams around the nest and made the web cam imagery available on the web for the public to view.

Duncan and Kite showed that hens were highly motivated to gain access to a nest box, particularly immediately prior to oviposition. The hens would push a weighted door, or walk through water or an air blast to reach a nest box. Duncan and Kite suggested the strength of this motivation was equivalent to that of the strength of motivation to feed after 20 hours deprivation.Duncan, I.J.H. and Kite, V.G., (1987) Some investigations into motivation in the domestic fowl.

Installing artificial cavity inserts and woodpecker banding and occasional transplanting are also important management tools. Other management practices include wood duck nest box project, fish stocking, and removal of exotic, invasive plants and animals.
|
|
Nest boxes should be cleaned between uses. Splay leg is a relatively common problem in baby budgerigars and other birds; one of the budgerigar's legs is bent outward, which prevents it from being able to stand properly and compete with the other chicks for food, and can also lead to difficulties in reproducing in adulthood. The condition is caused by young budgerigars slipping repeatedly on the floor of a nest box. It is easily avoided by placing a small quantity of a safe bedding or wood shavings in the bottom of the nest box.

Breeding pairs do not make good companion pets, as they cannot be handled if they are wanted for breeding. Pairs require a closed nest box in the place of a tree hole nest in the wild, in order to reproduce.

Similarly, the birds on the western Canary Islands which are usually assigned to the nominate subspecies have declined much, and here wanton destruction seems still to be significant. On Tenerife they seem relatively numerous but on the other islands, the situation looks about as bleak as on Fuerteventura. Due to their assignment to the nominate subspecies, which is common in mainland Spain, the western Canary Islands population is not classified as threatened. In the United Kingdom, the "Barn Owl Nest Box Scheme" is promoted by the World Owl Trust and has many participants in local areas such as Somerset, where a webcam has been set up inside a nest box in which seven young were reared in 2014.

The refuge has a large nest box program for prothonotary warblers and wood ducks. Wood ducks are banded on the refuge each year. An area of of former agricultural fields has been reforested with eleven bottomland hardwood tree species. Existing forested wetlands are managed for forest health and wildlife habitat.

A nestling tawny owl looks out from a nest box. Tawny owls are monogamous and territorial year around. Young birds select territories and look for mates in autumn and tend to be very vocal, especially males. Due to their highly territorial behaviour, young birds frequently struggle to establish a territory unless a nearby adult dies.

The "Cavalier" variation typically depicts a white figure. One legend has it that the first Groomsman was created at the commission of George Washington. Lighthouses: small-scale representations of local lighthouses are popular in coastal areas. Nest box/bird house: a small house for a bird normally made of wood and on a stake.

They are birds of deciduous woodlands, parks and gardens, with a preference for open areas amongst trees. They build an open nest in a suitable recess, often against a wall, and will readily adapt to an open- fronted nest box. 4-6 eggs are laid. Most European birds cannot discriminate between their own eggs and those of other species.
|
|
The chosen site is normally a tree, alive or dead, occasionally a utility pole or nest box. Old holes are rarely re-used, although the same tree may be used for nesting for several years. The nest cavity is deep with an entrance hole wide. It is excavated by both sexes, the male doing most of the chiselling.

A nest box scheme which was started by the North Gloucestershire Naturalists' SocietyGloucestershire Naturalists' Society in 1964, has supported the breeding birds. This one of the longest running schemes in Gloucestershire. Recordings show that these have been used by pied flycatcher, spotted flycatcher, nuthatch, wren, treecreeper and marsh tit in particular. Other breeding birds includes dunnock, song thrush and garden warbler.

|
Nuthatches are more reluctant to occupy a nest box than other tree hole nesting birds. Egg Nuthatches are monogamous, and a pair occupies a breeding territory in which it spends the winter as well. Territory sizes range from in Europe to an average of in the sub-optimal conifer forests of Siberia. The male sings to defend his territory and attract a mate.

Annually Nestwatch had cameras in birds' nests. It was similar to the setup of the BBC's Springwatch. One nest box was installed in the gardens of President Mary McAleese at Áras an Uachtaráin in 2009 at her own invitation. The male blue tit once went missing and the female blue tit had only laid six eggs, half of what was initially expected.

Like every sport out there, racing pigeons is an evolving sport. One of the most popular systems is widowhood. This system uses the birds' desire to reproduce as motivation to try to give the bird a sense of urgency on race day. The use of widowhood is usually begun by first allowing the racer to raise a baby in their nest box.

|
Skeletal adaptations and strengthening also help to absorb the shock, and narrow nostrils protect against flying debris. As well as using holes for breeding, great spotted woodpeckers roost at night, and sometimes during the day, in old nest cavities, excavated by other woodpeckers. They will occasionally make a new roosting hole or use an artificial site such as a nest box.

A breeding pair moved in and successfully reared two chicks. Although the birds occasionally used the (now destroyed) West Pier as well, Sussex Heights has been a successful breeding ground ever since. The Sussex Ornithological Society rings the chicks each year and has installed a webcam through which activity in the nest box can be viewed. As of 2010, 40 chicks have been reared.

European pied flycatcher vocalization They are birds of deciduous woodlands, parks and gardens, with a preference for oak trees. They build an open nest in a tree hole, and will readily adapt to an open- fronted nest box. 4-10 eggs are laid. The very similar Atlas pied flycatcher, of the mountains of north west Africa was formerly classed as subspecies of the European pied flycatcher.

Mountain bluebirds are cavity nesters and can become very partial to a nest box, especially if they have successfully raised a clutch. They may even reuse the same nest, though not always. Mountain bluebirds will not abandon a nest if human activity is detected close by or at the nest. Because of this, they can be easily banded while they are still in the nest.

Handy Brake NWR has a wood duck nest box project. Water levels are manipulated to provide optimal habitat for nesting and wintering ducks. The refuge lands cleared for agriculture prior to the establishment of the refuge have been reforested to bottomland hardwoods. An observation platform overlooks a permanent wetland, which is excellent habitat for wintering waterfowl, wading birds and many other wetland dependent species.

With macaws and amazons at a clay lick in Ecuador Consuming clay is believed to provide a mineral supplement and neutralise toxins in their diet. Their predators (along with many other neotropical parrots) include many birds of prey, monkeys, and in some cases, jaguars. They do well in captivity. They are fairly easy to breed if provided with a durable nest box, and will lay up to three clutches per year.

However, each generation is estimated to be about 6.6 years. Parallels in altitudinal migration with the equally solitary mockingbird might be taken as indication that the breeding activity peaked around March through April. In captivity, the female generally lays two white eggs in a nest box 1–2.5 m above ground. The incubation lasts from 14 to 17 days, and the young birds fledge after around 14 to 20 days.

The song of the juniper titmouse is a rolling series of notes given on the same pitch. Its call sounds like a raspy tschick-adee. This species builds its nest in a woodpecker hole, natural cavity, or nest box, lining it with grass, moss, mud, hair, feathers, and fur. It breeds from March into July, with peak activity in April and May, laying 3–9 eggs, usually 4–7.

Nest in a nest box The western bluebird nests in cavities or in nest boxes, competing with tree swallows, house sparrows, and European starlings for natural nesting locations. Because of the high level of competition, house sparrows often attack western bluebirds for their nests. The attacks are made both in groups or alone. Attacks by starlings can be reduced if the nesting box opening is kept to diameter to avoid takeover.

A nest box can also be regarded as an animal surveillance device. Surveilling animals can lead to the discovery of new scientific and industrial fields. For example, biologists and engineers can work on barn owl surveillance techniques and devices, while social scientists document the practices that cause humans to observe an animal. While the diet of the barn owl has been studied, other areas like breeding success are not well known.

Another barn owl nest box live- streaming webcam located in California, United States has proved popular online. In May 2012, it was revealed that farmers in Israel and Jordan had, over a period of ten years, replaced pesticides with barn owls in a joint conservation venture called "Project Barn Owl". Other research tools include using GPS trackers fitted onto the barn owl allowing precise location tracking of the owl.

A peregrine falcon nest box is located in the area. The 28th and 29th floors contain a gravity water-service system; two large tanks these levels feed the building. The 29th floor contains a lavatory for service to the Gondola rooms and adjoining balconies. In the basement is a vault, designed to house small and large items, supplied with storage areas for client possessions such as fine rugs.

The 24-storey tower was finished in 1968. The building had 91 two- bedroom flats and 24 with one bedroom, all with balconies, allocated garage space and leases of 125 years. The typical sale price of a two-bedroom flat in 1968 was recorded as £5,950 (£ in ); by 2006 it was £250,000 (£ in ). Peregrine falcons have nested at the top of Sussex Heights since early 1998, when a nest box was erected.

A purpose-built owl-house or owlery at a farm near Morton on the Hill, England (2006) Encouraging natural predators to control rodent population is a natural form of pest control, along with excluding food sources for rodents. Placing a nest box for owls on a property can help control rodent populations (one family of hungry barn owls can consume more than 3,000 rodents in a nesting season) while maintaining the naturally balanced food chain.

A nest box set out for tawny owls. The male advertises several potential nest sites to his mate by singing at the entrance, slipping inside and so on, with the female finally selecting one. The typical nest site of a tawny owl is a tree hollow, wherein the owls will nest directly on the interior hole's surface. Tree hollows used may be as much as above the ground, but are usually within about of the ground.

The more shallow cages can be connected back-to- back. To create space for large groups of hens, some designs of furnished cages are very long. Cage bottoms are made of wire mesh or plastic slats and are sloped so that eggs not laid in the nest box roll onto an egg belt. Feed is provided in feeders outside the cage, although in some designs there may be internal feeders or a combination of the two.

Since Sports and Charlies are undesirable most breeders will not use them in a breeding program and often time will cull them straight out of the nesting box. But some breeders will keep Sports and Charlies if their type (Body shape) is desirable. A pregnant English Spot will require adequate food to support her and her young. Four weeks into the pregnancy, it is common for breeders to provide the doe with a nest box filled with straw.

The song of the oak titmouse is a series of repeated whistled notes of three to seven syllables, with first syllable higher in pitch than the following one. The call is a scratchy tsicka-dee-dee. The oak titmouse builds its nest in a woodpecker hole, a natural cavity, or a nest box, using grass, moss, mud, hair, feathers, and fur. It breeds from March into July, with peak activity in April and May, laying 3–9 eggs, usually 6–8.

In August 2004, as many as thirteen grown ducks plus a brood of eight were observed, indicating an increasing population of this tropical species. The well-established wood duck nest box program produces about 2,000 wood duck hatchlings a year. The boxes are prepared early in the year and checked frequently during nesting season to track hatches and remove non-viable eggs. In addition to waterfowl, the white-tail deer is abundant; hunting is allowed for most native game species except waterfowl.

|
If a nest gets too cold or a baby falls out, they will get dark bands on their fur. This varies from looking to off-white to looking chinchilla-colored, and it causes confusion among many novice breeders. Because of their constantly changing colors, most Himalayan breeders do not look at markings as a factor when making breeding plans. A baby who was chilled in the nest box is often called "frosty," which is not to be confused with frosted pearl.
|
|
Depending on the clutch size and the beginning of incubation, the age difference between the first and last hatchling can be anywhere from 9 to 16 days. At times, the parents may begin eating their own eggs due to feeling insecure in the nest box. Sometimes, budgerigars (mainly males) are not interested in the opposite sex, and will not reproduce with them; a flock setting—several pairs housed where they can see and hear each other—is necessary to stimulate breeding.

The database is being used by researchers to model and understand relationships between kestrel nesting parameters (e.g., phenology, occupancy, survival, productivity, and nestling weight and exposure to environmental toxins) and environmental factors, such as land use, landscape composition and configuration, climate conditions (e.g., drought), and point sources of environmental toxins. Each breeding season, the American Kestrel Partnership features a live-streaming video feedLive-streaming video feed, The Peregrine Fund from the nest box located at The Peregrine Fund's campus in Boise, Idaho.

He received the Dickin Medal in May 1945. Communications in that battle were a problem for the Allied units; German troops had surrounded the airborne forces and the few radio sets present malfunctioned. William of Orange was released by British soldiers at 10:30 on 19 September 1944 and arrived at his nest box in England at 14:55. He flew over 400 km (250 mi) and the message he carried was one of few to make their way back to the United Kingdom.

The nest box was threatened with removal in January 2010 when renovation work was scheduled, but this did not happen and the 2010 breeding season produced two chicks. In November 2013, Sir Terence Conran's architectural practice Conran and Partners—who had recently worked on Embassy Court and Saltdean Lido elsewhere in the city—were commissioned to refurbish the building. Work was expected to begin in spring 2014. At tall, Sussex Heights is the tallest building in Sussex and the only building in Sussex taller than .

A nest box should be provided for the new mother two to five days prior to the expected kindling date. The doe will pull fur from her abdomen and dewlap and along with hay or other materials provided she will create a nest. The young are born hairless, deaf, and blind. Fur begins to grow in by day 3 to 5 and after 7 to 10 days the kits' eyes will open by 2 weeks they may begin exploring and sampling outside food sources.

Because of this, most potential breeding colonies for red- footed falcons disappeared, causing a decline in the number of breeding pairs. Conservation projects have established artificial nest box colonies to rectify this problem. There is little evidence of this plan's effectiveness and also little evidence on recent population trends and distribution, from Northern Serbia, where 5-10% of the total European Union population is thought to breed. The researchers' main focus was on understanding the relationship between landscape scale habitat variables and red-footed falcon presence.
|
|
This decline is a result of longleaf pines being cleared from agricultural fields. Despite this, the American kestrel is classed as least concern on the IUCN Red List. The Peregrine Fund, a leading non-profit organization advancing research and conservation of birds of prey worldwide, launched the American Kestrel Partnership in 2012. The American Kestrel Partnership developed and maintains a web-based network for citizen and professional scientists to enter, manage, and consolidate data from kestrel nest box monitoring programs in the Western Hemisphere.

Bird nests are also built by humans to help in the conservation of certain birds (such as swallows). Swallow nests are generally built with plaster, wood, terracotta or stucco.Artificial swallow nests Terracotta nests Artificial nests, such as nest boxes, are an important conservation tool for many species, however nest box programs rarely compare their effectiveness with individuals not using nest boxes. Red-footed falcons using nest boxes in heavily managed landscapes produced fewer fledglings than those nesting in natural nests, but also than pairs nesting in nest boxes in more natural habitats.
|
|
To involve citizens in the conservation movement and get them emotionally attached to the cause of conservation, the Nature Forever Society initiated a program where people could adopt a nest box and/or bird feeder. By doing this they would not only provide a habitat for the birds to nest in their homes but also get attached to the cause. So far a large number of nest boxes and bird feeders have been adopted from across the country and taking inspiration from NFS, numerous organisations and individuals have initiated this across the country.

Suitable nesting hollows may be used quite often in subsequent years, with records of a single hollow seeing up to 25 years of barred owl use (presumably not by the same owls however). Other long-used nests were one reused in New England for 10 years by the same pair until it rotted out and while a nest box in Nova Scotia was reused 10 times over 16 years. Over 6 years in Minnesota, 14 nest boxes were reused; 7 were used once, 6 were twice and one was used three times.Johnson, D. H. (1987).

Violet-green swallows have been observed cooperating and competing with various avian species, including western bluebirds. A similar field observation notes a violet-green swallow laying an egg in an active bluebird nest box. Initially, the male bluebird attempted to drive the swallow from the nest cavity, while the female bluebird did not seem concerned with the intruder. It appeared the bluebirds tolerated the act of egg-dumping by the violet-green swallow, but the observer returned the following day to find the newly laid egg smashed below the nest.
|
|
Nests are made in holes in trees, fence posts or logs lying on the ground; the four to six eggs are incubated for 18–21 days, with the young fledging about 30 days after hatching. In the wild, virtually all parrot species require a hollow tree or a hollow log as a nest site. Because of this natural behaviour, budgerigars most easily breed in captivity when provided with a reasonable-sized nest box. The eggs are typically one to two centimetres long and are pearl white without any colouration if fertile.
|
|
After the baby is weaned the hen is removed and often the nestbox is closed off, from then on the only time these birds are allowed to see their mate or enter the nest box is upon returning from training or a race. This conditioning is one of the key elements in a lot of racing programs. Due to advancements in technology researchers have been able to use small Global Positioning Systems to track the flight paths that their birds follow. Small GPS systems have recently begun to hit the consumer market.

Mixed-forests are one of the habitats great tits use in Europe At nest box in Altenbeken, Germany The great tit has a wide distribution across much of Eurasia. It can be found across all of Europe except for Iceland and northern Scandinavia, including numerous Mediterranean islands. In North Africa it lives in Morocco, Algeria and Tunisia. It also occurs across the Middle East, and parts of Central Asia from northern Iran and Afghanistan to Mongolia, as well as across northern Asia from the Urals as far east as northern China and the Amur Valley.

In additional, any variety of small mammal, to the size of hares (albeit usually young ones), may too be fairly often taken, as well as variable numbers of birds, amphibians and invertebrates, with reptiles and perhaps fish being very rare prey. Across the wide distribution, the Ural owl is known to take more than 200 prey species, of which more than 80 are mammals.Vrezec, A., Saurola, P., Avotins, A., Kocijančič, S., & Sulkava, S. (2018).

A Ural owl in Slovakia sitting on its nest, a natural tree cavity. An adult Ural owl emerging from a nest box in Siberia, the use of which has bolstered the populations of the species. Potential nesting sites include large natural holes in trees, cavities left by large branch that have broken off, hollow trunks where canopies have been broken off (or "chimney stacks"), fissures or holes in cliffs or between rocks and holes in buildings. Tree crags and stumps used preferentially in central and eastern Europe are quite often common birch (Fagus sylvatica) or occasionally common oak (Quercus robur).

Senegal parrots are relatively easy to breed in captivity and there is a small industry in breeding and hand rearing Senegal parrots and other parrots for the pet trade. In aviculture Senegal parrots can start to breed at the age of 3 to 4 years in captivity, but some do not breed until age 5 years. Parent reared birds are known to breed as early as 2 years of age. Senegal parrot nest boxes can be any of a variety of sizes and shapes; but for example, a nest box about high and to square would be suitable.

A conservation program, which was funded by the EU's LIFE Nature financial instrument, was initiated on January 1, 2006 with the goal of increasing and maintaining the breeding population of the species in Hungary and western Romania. This conservation project developed a method to create more nesting sites by creating artificial nest box colonies. It's pretty common for the birds to be preyed upon by martens or other mammalian predators during incubation or during the nestling state, even in the artificial colonies. Some extreme cases show that the predators may threaten the existence of every clutch in the colony.

It is advisable to clean them, but keep them up even after breeding season. The risk of losing a bird to egg laying complications (in the unlikely event they do decide to breed in the winter), is out-weighed by the benefit of keeping the birds content, keeping pair-bonds strong, & the reduced risk of losing a bird to the cold. A supply of willow branches, and roughly slivered corn, or maize husk can be given in the aviary as nesting box lining: It will be ripped up, & carried into the nest box by the female. Lovebirds are reasonably difficult to sex.

Female (left) and male (right) at Eastern Creek, New South Wales, Australia Red rumps are bred easily in captivity if provided with necessary flight space and a large nesting box. Breeders usually use peat and wood shavings as bedding for the nests, birds like to arrange the beds to their likings. As soon as mating has occurred the hen will deposit 4 to 7 eggs which she will brood for about 20 days. Red rump hens will not go out of the nest box whilst on eggs and not even human checking will make them leave their eggs alone.

In several parts of their range they may make use of nest boxes, with the trend of nest box placement beginning and being perhaps most persistently used in Fennoscandia. Large nest boxes with an opening of about in diameter are preferred by the species. Elsewhere, about 29% of nest boxes set out in Slovenia are known to have been used. In Russia’s Altai Krai, Biya River area between 2010 and 2012, 15.2-48.9% of nest boxes that were erected were used with annual variation explainable by cycles of primary food sources. In Samara Oblast of 74 nest boxes set in 4 study plots by 2009, 41.9% were used by Ural owls (with about 14.9% used by various other animals).

Peregrine falcons have nested atop the building since 2003 and a camera was installed so that their nest box could be live streamed to the public. In 2011, Room 25 located on the Lower Level, was transformed into a "Team Based Learning Classroom" that can hold approximately 75 students. In time for the fall 2017 semester, a refresh of the lobby was completed included the installation of new digital signage and a new information desk, the Graduate Commons was opened on the 5th floor, and a second teaching space was finished for the Archives. The Science and Engineering Library, which holds the bulk of the STEM related collection is located at a separate location in the Lederle Graduate Research Center Lowrise.

The Dovecote at High House High House is the collective name for a group of historic buildings in Purfleet, Thurrock, Essex,Nikolaus Pevsner, The Buildings of England, Essex, London, 1954, Penguin p.289 which was used as a farm for hundreds of years, with a Grade II listed house and barn, but with the addition of one of the best dovecotes (dove houses) in Southern England, which is a Scheduled Ancient Monument and notable for its nest box array. This property includes the house, coachman's cottage, chaise house, stable, granary, barn, workshop, cart sheds, dovecote, and inner and outer walled gardens. Known by many names in its past, the farm has been called Le Vineyards, because grape vines were grown on one of its south facing slopes.

It will sometimes attempt to take over the nest of other birds that breed in holes or enclosed spaces, such as the barn swallow, house martin, sand martin or European bee-eater. Pairs may breed in isolation or in loose colonies, and will readily use nest boxes. In a Spanish study, boxes made from a mixture of wood and concrete (woodcrete) had a much higher occupancy rate than wooden boxes (76.5% versus 33.5%), and birds nesting in woodcrete sites had earlier clutches, a shorter incubation period and more breeding attempts per season. Clutch size and chick condition did not differ between nest box types, but reproductive success was higher in woodcrete, perhaps because the synthetic nests were 1.5 °C warmer than their wooden counterparts.

"Vacation Scholars' Meeting", Universities Federation for Animal Welfare News-Sheet, March 2004, p. 6. He went on to conduct extensive studies on laboratory cage design, showing that mice kept in ordinary cages chose to drink more of an anxiety-reducing drug than mice housed in larger cages with nesting material, a nest box, and a running wheel, where they could burrow and be with other mice. He trained mice to open a lever to access cages with more space, varying how often the lever had to be pressed, and found that more space was something they were willing to work for. He found that cage colour affected mouse welfare, including body weight; the mice liked white cages most and red least.

The Eurasian blue tit will nest in any suitable hole in a tree, wall, or stump, or an artificial nest box, often competing with house sparrows or great tits for the site. Few birds more readily accept the shelter of a nesting box; the same hole is returned to year after year, and when one pair dies another takes possession. It is estimated by the RSPB that there are 3,535,000 breeding pairs in the UK. During the incubation period, female blue tits perform most, if not all, of the incubation, however the male feeds the female during this time, with both female nest attendance and male feeding rate higher in the morning, declining throughout the day. Eggs are long and wide.

The wide range of species is mainly due to Brandon Marsh being one of the few extensive areas of water in the area (accounting for such local rarities as osprey and whooper swan) together with the existence of habitats such as reedbed and woodland in close proximity. 148 different species were recorded during 2009 alone--including one new record, a vagrant woodchat shrike which was the first recorded in Warwickshire--and 66 species bred at the site. These figures have been assisted by a nest box scheme; in 2008 there were 49 occupied nest boxes which produced 270 fledged young, and by 2009 these numbers had increased to 65 and 352 respectively, including two owl species, barn owl and tawny owl. As well as birds, the reserve also harbours a varied selection of mammals.

Famine scholar Alex de Waal observes that while the famine that struck the country in the mid-1980s is usually ascribed to drought, "closer investigation shows that widespread drought occurred only some months after the famine was already under way." Hundreds of thousands fled economic misery, conscription, and political repression, and went to live in neighboring countries and all over the Western world, creating an Ethiopian diaspora for the first time. A civil war took place that left many deads. Nest box for Columba guinea (considered a peace bird) in the wall of a homestead in Zerfenti, a village in Tigray where hundreds were killed by Derg bombings Towards the end of January 1991, a coalition of rebel forces, the Ethiopian People's Revolutionary Democratic Front (EPRDF) captured Gondar, the ancient capital city, Bahar Dar, and Dessie.

Orchards, which often have trees with crevices and holes, as well as meadow voles (Microtus pennsylvanicus), a dietary favorite, are often preferred nesting habitats. Eastern screech owls also use nesting boxes erected by humans. Although some people put up nest boxes meant for screech owls, the owls also take over nest boxes meant for others, such as those for wood ducks (Aix sponsa), houses erected for purple martins (Progne subis), and dovecotes put up for rock pigeons (Columba livia), occasionally killing and consuming at least the latter two in the process of taking over the nest box. A 9-year study comparing the breeding success of eastern screech owls nesting in natural cavities and nesting in nest boxes showed that the fledging rate was essentially the same, although in some years, up to 10% more success occurred in the natural cavities.
