Crepuscular rays as seen from Taipei, Taiwan (2018) Crepuscular rays or "God rays" are sunbeams that originate when the sun is below the horizon, during twilight hours. Crepuscular rays are noticeable when the contrast between light and dark is most obvious. Crepuscular comes from the Latin word "crepusculum", meaning twilight. Crepuscular rays usually appear orange because the path through the atmosphere at sunrise and sunset passes through up to 40 times as much air as rays from a high midday sun.

|
Fireflies at twilight, long exposure The various patterns of activity are thought to be mainly antipredator adaptations, though some could equally well be predatory adaptations. Many predators forage most intensively at night, whereas others are active at midday and see best in full sun. Thus, the crepuscular habit may both reduce predation pressure, thereby increasing the crepuscular populations, and in consequence offer better foraging opportunities to predators that increasingly focus their attention on crepuscular prey until a new balance is struck. Such shifting states of balance are often found in ecology.

D. russelii hunting D. russelii feeds primarily on rodents, although especially it will also eat small reptiles, land crabs, scorpions, and other arthropods. Juveniles are crepuscular, feeding on lizards and foraging actively. As they grow and become adults, they begin to specialize in rodents. Indeed, the presence of rodents and lizards is the main reason they are attracted to human habitation.

Pt. Deen Dayal Upadhyaya Park is another small garden located on the adjacent hillock to Manikya Lal Verma Garden. It was developed by Urban Improvement Trust (UIT) Udaipur. It also has Rajasthan's first "Musical Fountain" manufactured by "Yagnik Mechanical Engineering Works". It offers a sunset point, from where the sun sets in the lap of lake Pichola reflecting crepuscular light.

Gynacantha millardi is currently known from India and Sri Lanka while the widespread G. bayadera is known from Northeast India to South China and northern New Guinea. It is unclear if the two species overlap in distribution and a review of records of both species from the Indian subcontinent is needed. It is crepuscular and flies low in shady places.
|
|
Infants are quite precocial, and develop quickly, similar to other juveniles in the genus. The offspring begin capturing their own prey around 42 days of age, and travel in groups after only 23 days. Young females remain with parents until adulthood, while young males leave the natal group as juveniles. The pygmy tarsier is nocturnal or crepuscular, and is mainly arboreal.

The bipedal locomotion of jerboas involves hopping, skipping and running gaits. It is associated with rapid and frequent, difficult-to-predict changes in speed and direction, facilitating predator evasion relative to quadrupedal locomotion. This may explain why evolution of bipedal locomotion is favored in desert dwelling rodents that forage in open habitats. Jerboas are crepuscular, meaning that they are most active at twilight.
|
|
The common genet is solitary. Adults are nocturnal and crepuscular, with their highest levels of activity following sunset and just prior to sunrise; juveniles may be active during the day. They rest during the day in hollow trees or among thickets, and frequently use the same resting sites. In southern Spain, adult individuals occupy home ranges of about in average.
|
|
Like other frogmouths, this species is nocturnal and crepuscular. It feeds on such insects as butterflies and moths, ants, grasshoppers, cicadas, beetles, earwigs, cockroaches, caterpillars and small molluscs. Food may be picked up from the ground or gleaned from foliage and branches, or perhaps caught on the wing. It roosts fairly close to the ground, singly or in pairs, crosswise on small branches.
|
|
There is not much information about the Plain- tailed nighthawk because it is a newly identified species but it is known that they are crepuscular (active at dawn and dusk) and nocturnal (active at night) and they sleep on the ground where they can easily camouflage. They have been observed above the river in flocks of up to 20 individuals during dusk hours.
|
|
Tiger spiders are nocturnal and crepuscular hunters. They come out to forage in dusk and dawn. Unlike many other spiders, they do not use a cobweb to catch prey. Instead, they are ambush predators, where they sit and wait until the prey comes closer or passes by, then follow the prey with exceptional speed, catch it, and inject venom to immobilize it.
|
|
The marsh mongoose is solitary. It is an excellent swimmer and can dive for up to 15 seconds, using its feet to paddle. On land, it usually trots slowly, but can also move fast. Radio-collared marsh mongooses in Kwa- Zulu Natal showed crepuscular activity, and were active from shortly after sunset until after midnight, but not during the day.
|
|
However, they are predominantly crepuscular. They consume about 5.5% of their body weight per day. They sometimes take advantage of the disturbances made by boats to catch disoriented prey. Sometimes, they associate with the distantly- related tucuxi (Sotalia fluviatilis), and giant otters (Pteronura brasiliensis) to hunt in a coordinated manner, by gathering and attacking fish stocks at the same time.
|
|
A late spring was followed by a low rate of maturation of young-of-the-year females. In dense populations of northern red-backed voles, sexual maturation of young females may be delayed, or they may migrate to a vacant breeding space. Northern red-backed voles are mainly nocturnal and crepuscular but are of necessity about during the prolonged arctic daylight season.
|
|
Montane fish-eating rats are either crepuscular or nocturnal. Despite their common name, they have never been observed to eat fish. Instead, the stomach contents of the few specimens examined consist solely of freshwater invertebrates, such as scirtid water beetles, crane flies, mayflies, stoneflies, and caddisflies. Little else is known of their habits and biology, because only 47 specimens have ever been collected.
|
|
Micrurus mipartitus is a species of crepuscular and nocturnal habits. During period of low rainfall, could be located underground several centimeters deep. In times of high rainfall it's found on soil surface or where leaf litter is abundant. This coral snake lives from tropical dry forest to foggy forests and is related to human settlements in rural areas used for agriculture.
|
|
Female paradise-kingfishers are known to use their long tails to clear the loose soil. Some crepuscular petrels and prions are able to identify their own burrows within dense colonies by smell. Sand martins learn the location of their nest within a colony, and will accept any chick put into that nest until right before the young fledge. Not all burrow-nesting species incubate their young directly.
|
|
Little is known about the behavior of the gray-bellied caenolestid. It appears to be terrestrial (land-living) and crepuscular (active around twilight) or nocturnal (active at night). It appears to be an "opportunistic feeder". Analysis of stomach contents of individuals from Peru suggested a diet comprised largely (up to 75%) by invertebrate larvae (such as arachnids and centipedes); small vertebrates and plant material are also consumed.

Gretna balenge, the giant crepuscular skipper, is a butterfly in the family Hesperiidae. It is found in Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Central African Republic, the Democratic Republic of the Congo, Uganda, Tanzania and Zambia.Afrotropical Butterflies: Hesperiidae - Subfamily Hesperiinae The habitat consists of all areas where suitable palms grow. Adults are attracted to various kinds of foul substances.
|
|
It is a crepuscular dragonfly, active in the dusk. This species can be easily distinguished by the multicolored upper surface of frons and by the shape and relative lengths of the anal appendages. Its labium and labrum are golden- yellow and face and frons are greenish yellow and eyes are green, bluish when aged. Its thorax is pale olivaceous brown with dark brown sutures.
|
|
They are crepuscular and nocturnal in habits. Aggression among badgers is largely associated with territorial defence and mating. When fighting, they bite each other on the neck and rump, while running and chasing each other and injuries incurred in such fights can be severe and sometimes fatal. When attacked by dogs or sexually excited, badgers may raise their tails and fluff up their fur.
|
|
Black spots are present on anterior wings, and the females are wider and more voluminous than the males. The pest mainly presents nocturnal habits, and adults usually remain hidden during the day, showing greater morning-crepuscular activity with adults dispersing among crops by flying. Among a range of species within the Solanaceae, tomatoes (Lycopersicon esculentum Miller) appear to be the primary host of T. absoluta.
|
|
Therea petiveriana, variously called the desert cockroach, seven-spotted cockroach, or Indian domino cockroach, is a species of crepuscular cockroach found in southern India. They are members of a basal group within the cockroaches. This somewhat roundish and contrastingly marked cockroach is mainly found on the ground in scrub forest habitats where they may burrow under leaf litter or loose soil during the heat of the day.
|
|
H. reaumuri differs from other desert woodlice in a number of respects. It is crepuscular, while other species are nocturnal. Apart from at the highest temperatures, it is also positively phototactic (is attracted to sunlight), while other species are negatively phototactic (move away from bright light). Compared to other woodlice, H. reaumuri walks in an unusual manner, with its body held high off the ground.

|
The rock shelter for which Indian Cave State Park is named. Rock shelter in the Little Carpathians A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves (karst), which are often many miles long, rock shelters are almost always modest in size and extent.
|
|
Dustywing larvae are around 3.5 mm long. Their mouthparts consist of short, straight sucking tubes covered by the labrum (upper "lip"). They are crepuscular and dwell on shrubs and trees, where they feed on small invertebrates like scale insects, aphids and mites, as well as on arthropod eggs; the mouth tubes are used for sucking fluids from the prey. There are usually two generations each year.
|
|
The group leaves the sleeping tree together an hour after dawn and spends the day foraging, resting, travelling, and grooming. The species is thought to rise late and increases the speed of its foraging and travelling before dusk to avoid crepuscular and nocturnal predators. Its main predators include raptors, mustelids, felids, and snakes. The cotton-top tamarin is extremely vigilant, always looking for potential predators.

In atmospheric optics, a photometeor is a bright object or other optical phenomenon appearing in the Earth's atmosphere when sunlight or moonlight creates a reflection, refraction, diffraction or interference under particular circumstances. The most common examples include halos, rainbows, fogbows, cloud iridescences (or irisation), glories, Bishop's rings, coronas, crepuscular rays, sun dogs, light pillars, mirages, scintillations, and green flashes. Photometeors are not reported in routine weather observation.
|
|
The tufted deer is mainly solitary or found in pairs. It is crepuscular and travels in fixed routes about its territory, which is vigorously defended by the males. It is a timid animal and prefer places with good cover, where it is well camouflaged. It can be easily disturbed and, when alarmed, it will let out a bark before fleeing, moving in cat-like jumps.
|
|
Swift moths are crepuscular and some species form leks, also thought to have arisen independently in the genus Ogygioses (Palaeosetidae). In most genera, males fly swiftly to virgin females that are calling with scent. In other genera, virgin females "assemble" upwind to displaying males,Mallet, J. 1984. Sex roles in the ghost moth Hepialus humuli (L.) with a review of mating in the Hepialidae (Lepidoptera).
|
|
Gargoyle geckos are crepuscular and arboreal, making their home in scrub forests. The female lays two eggs per clutch, which hatch 60 to 90 days after they are laid. The female can lay eight or nine clutches per year. In captivity, it is fairly easy to hand tame these geckos, because they adapt to a human touching them, and know food comes when one is around sometimes.
|
|
Homosexual fellatio has been observed in at least one species, the Bonin flying fox (Pteropus pselaphon). This same-sex fellatio is hypothesized to encourage colony formation of otherwise-antagonistic males in colder climates. Megabats are mostly nocturnal and crepuscular, though some have been observed flying during the day. A few island species and subspecies are diurnal, hypothesized as a response to a lack of predators.
|
|
The scales on the underside vary from light yellow to different shades of green. The toes on all four legs have thick, curved nails used for climbing and gripping tree limbs. As a crepuscular animal, it is most active during the dusk and dawn hours, feeding primarily at dusk. it also is active and eats during the hours of dawn, though to a lesser extent.
|
|
Five radio-collared binturongs in the Phu Khieo Wildlife Sanctuary exhibited an arrhythmic activity dominated by crepuscular and nocturnal tendencies with peaks in the early morning and late evening. Reduced inactivity periods occurred from midday to late afternoon. They moved between and daily in the dry season and increased their daily movement to in the wet season. Ranges sizes of males varied between and .

|
The lesser nighthawk retreats from the United States and northern Mexico during the winter months. Occasionally single birds may be found overwintering. The nighthawk is also occasionally found as a vagrant to the US Gulf Coast states to Florida. They catch flying insects on the wing, mainly foraging near dawn and dusk (crepuscular), sometimes at night with a full moon or near street lighting.
|
|
Nightjars are most active, and mostly feed, near dawn and dusk (crepuscular - active during the twilight). At dusk, they often fly around livestock to feed on insects swarming around the animals. At night, they like to take advantage of insects swarming around street lamps or other artificial light sources. They are keeping their bills wide open as they fly through clouds of small insects.
|
|
Tropical Asio owls are largely sedentary. These owls hunt over open fields or grasslands, taking mainly rodents, other small mammals and some birds. Asio owls are mainly nocturnal, but short-eared owls are also crepuscular. Most species nest on the ground, but the long-eared owl (Asio otus) nests in the old stick nests of crows, ravens and magpies (family Corvidae) and various hawks.
|
|
Cricosaura typica is a xerophilic species which hides under rocks, stones, logs, and debris in xeric forest and woods in microhabitats with at least some humidity. It is crepuscular and to some degree diurnal but lives very secretive. In their habitats it is quite common and can be easily collected during the day. In loose soil it progresses by snake-like wiggling and head movement.
|
|
This frog is diurnal and crepuscular and it is commonly found along the banks of small, rocky streams with clear water in primary rainforests. They can often be seen perched on rocks or other vegetation near water, usually around the rapids. They breed in streams and the males vocalize during the day. Like other members of Staurois, they use visual signalling to attract a mate.
|
|
Hedgehogs may tighten the orbicularis muscle on their back to hide their head, legs, and belly in a coat of prickly erect spines. Hedgehogs are primarily nocturnal, though some may be crepuscular. Hedgehogs typically take refuge in the empty burrow of another small animal, or a burrow they dug themselves. However, hedgehogs can occasionally take refuge under rocks or in thick vegetation, or anywhere dark and secluded.
|
|
Guinea pigs do not store their food. They typically travel in groups, or herds, scavenging for grass and other vegetation. They are commonly active during dawn or dusk when they are less likely to encounter predators (crepuscular). As pack animals in the wild, the domestic Guinea pig also thrives when kept with one or more companions (except boars in the presence of a sow).
|
|
It also captures small bats and small birds in flight. Its speed and aerobatic skills enable it to take swallows and even swifts on the wing, and barn swallows or house martins have a characteristic "hobby" alarm call. It is known to harass swallows while they are roosting and dispersing from roosts. When not breeding, it is crepuscular, hawking principally in the mornings and evenings.
|
|
The slug is mostly nocturnal or crepuscular but in Ireland it is active on overcast days. It feeds on lichens, liverworts, mosses and fungi, which grow on boulders and tree trunks. The Kerry slug is protected by conservation laws in the three countries in which it occurs. It is now known to be less dependent on sensitive, wild habitats than when these laws were introduced.
|
|
In Aedes, the search for a host takes place in two phases. First, the mosquito exhibits a nonspecific searching behavior until the perception of a host's stimulants, then it follows a targeted approach. Most mosquito species are crepuscular (dawn or dusk) feeders. During the heat of the day, most mosquitoes rest in a cool place and wait for the evenings, although they may still bite if disturbed.
|
|
North American river otters are active year-round, and are most active at night and during crepuscular hours. They become much more nocturnal in the spring, summer, and fall seasons, and more diurnal during winter. They may migrate as a result of food shortages or environmental conditions, but they do not migrate annually. North American river otters only settle in areas that consist of vegetation, rock piles, and sufficient coverage.

The gray-bellied caenolestid (Caenolestes caniventer), or grey-bellied shrew opossum, is a shrew opossum found in humid, temperate forests and moist grasslands of western Ecuador and northwestern Peru. It was first described by American zoologist Harold Elmer Anthony in 1921. Little is known about the behavior of the gray-bellied caenolestid. It appears to be terrestrial (land- living) and crepuscular (active around twilight) or nocturnal (active at night).
|
|
Since Podogymnura truei are ground dwellers, their typical diet includes earthworms, insects, and arthropods. Although primarily carnivorous, they will occasionally eat fungi and fruit. P. truei are nocturnal or crepuscular, which means that they remain in their burrows during the day, but come out to forage by searching the forest floor at twilight or night. Foraging with little visibility requires their sense of smell to be their primary sense.

Gretna waga, the common crepuscular skipper, is a butterfly in the family Hesperiidae. It is found in Senegal, the Gambia, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Democratic Republic of the Congo and Uganda.Afrotropical Butterflies: Hesperiidae - Subfamily Hesperiinae The habitat consists of forests and open areas in the forest zone. Adults have been recorded feeding on the nectar of asclepiad flowers.

Gretna cylinda, the lesser crepuscular skipper, is a butterfly in the family Hesperiidae. It is found in Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Central African Republic, Angola, the Democratic Republic of the Congo, southern Sudan, Uganda and north-western Tanzania.Afrotropical Butterflies: Hesperiidae - Subfamily Hesperiinae The habitat consists of forests. Adults are attracted to flowers, including those of Clerodendron splendens.
|
|
Bat roosts can be found in hollows, crevices, foliage, and even human-made structures, and include "tents" the bats construct with leaves. Megabats generally roost in trees. Most microbats are nocturnal and megabats are typically diurnal or crepuscular. Microbats are known to exhibit diurnal behaviour in temperate regions during summer when there is insufficient night time to forage, and in areas where there are few avian predators during the day.
|
|
Anurognathids are often believed to have been nocturnal or crepuscular akin to bats. The fact that many anurognathids have large eye-sockets supports the theory of living in darkness. Anurognathid teeth suggest they were insectivorous, though some may have had more prey-choices, such as Jeholopterus who is also believed to have been a fish-eater. At least some, such as Vesperopterylus, were arboreal, with claws suited for gripping tree branches.
|
|
These tarantulas hide themselves in long tubes that they dig under the surface or use abandoned rodent burrows. It is a crepuscular and nocturnal species and it is quite defensive.Basic Tarantulas When threatened this species will stridulate (hiss) to warn predators, it may also rear up and expose its fangs. Another self-defence mechanism of this spider is to use its back legs to flick urticating hairs from its abdomen.
|
|
They can be differentiated from other bats due to their dog-like faces, clawed second digits, and reduced uropatagium. Only members of one genus, Notopteris, have tails. Megabats have several adaptations for flight, including rapid oxygen consumption, the ability to sustain heart rates of more than 700 beats per minute, and large lung volumes. Most megabats are nocturnal or crepuscular, although a few species are active during the daytime.
|
|
The body is elongated and slender and terminates in two extensible graspers bearing tiny hooks; these are used to aid in locomotion and to grasp prey. The larvae are associated with damp, mossy habitats and are amphibious. They hunt small invertebrate prey, from which they suck the body fluids with their mouthparts. The adults are diurnal or crepuscular weak-flying insects which mostly prey on small invertebrates, supplemented with some pollen.
|
|
The genus includes primarily nocturnal or crepuscular moths that are found in the Australasian tropical areas. Species have a generally pale or nearly-white colouration with brown or dark patterns.The Swallowtail Moths (Uraniidae, Uraniinae) of Papua Indonesia by Siep and Jannie Sinnema The larvae live in webbing of the host plant.Jeremy Daniel Holloway, Geoffrey Kibby & Djunijanti Peggie, The Families of Malesian Moths and Butterflies (Fauna Malesiana Handbooks, Vol.

Wolves, Behavior, Ecology, and Conservation. The University of Chicago Press, 2006, p. 98. As crepuscular hunters, dogs often rely on their vision in low light situations: They have very large pupils, a high density of rods in the fovea, an increased flicker rate, and a tapetum lucidum. The tapetum is a reflective surface behind the retina that reflects light to give the photoreceptors a second chance to catch the photons.

Feeding House mice usually run, walk, or stand on all fours, but when eating, fighting, or orienting themselves, they rear up on their hind legs with additional support from the tail – a behavior known as "tripoding". Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. Mice are mostly crepuscular or nocturnal; they are averse to bright lights.
|
|
The awls and related genera have long, narrow forewings, rounded hindwings with a characteristic deep fold at the inner margin and produced at the tornus. The adult sexes are alike excepting that males have specialised scales and scent brands on the forewings. They have large labial palpi which have a thin third segment protruding ahead of the eye. The eyes are large, an adaptation to the crepuscular habits of this species.
|
|
The red-thighed sparrowhawk is a secretive and crepuscular species that spends most of the day perched in the interior of the forest. Its main prey is small birds up to the size of pigeons as well as lizards, amphibians, and insects. Prey is captured in quick dashes from a perch in the forest understory. This species often hunts co-operatively in pairs to harass mixed-species bird flocks.
|
|
The red-chested buttonquail feeds on seeds (grasses, Triticum, Panicum and Malvaceae) and insects (cockroaches, ants, flies and larvae). Foraging occurs throughout the day, although the species has been said to be nocturnal and crepuscular. They make platelets while foraging, which is typical for the genus Turnix. They glean and scratch in leaf litter, while rotating on the spot by pivoting on one foot and raking with the other.
|
|
The abdomen in many crepuscular species is raised at rest, mimicking a broken twig. When disturbed, some owlflies release a strong, musk- like chemical to deter enemies. Some New World species such as ' are able to suddenly reflex a flap on the pronotum, exposing a strongly-contrasting patch of pale colour (white or cream), either as a deimatic display to startle predators, or as heliographic signalling to attract females.
|
|
Its long, thin legs and dense reddish coat give it an unmistakable appearance. The maned wolf is a crepuscular and omnivorous animal adapted to the open environments of the South American savanna, with an important role in the seed dispersal of fruits, especially the wolf apple (Solanum lycocarpum). The maned wolf is a solitary animal. It communicates primarily by scent marking, but also gives a loud call known as "roar-barking".
|
|
They are terrestrial and crepuscular, and have moveable eyelids, vertical pupils, and no adhesive lamellae (sticky feet). The African fat-tailed gecko is found in West Africa, from Senegal to Cameroon. Their habitat is dry and arid, although they will spend most of their time in a dark, humid hiding place. In captivity, it is important to provide these geckos with a source of humidity that mimics these conditions.
|
|
As a result, the path of an object's shadow through the fog becomes visible as a darkened volume. In a sense, these shadow lanes are the inverse of crepuscular rays caused by beams of light, but caused by the shadows of solid objects. Theatrical fog and strong beams of light are sometimes used by lighting designers and visual artists who seek to highlight three-dimensional aspects of their work.
|
|
Rüppell's foxes are monogamous and either crepuscular or nocturnal, sheltering during the day in dens. Outside of the breeding season, these are small dens that can hold only one adult fox, and the animal typically changes dens every five days or so. Breeding dens are larger, and occupied by a pair of adults and their kits. Such dens can sometimes have more than one entrance, although this is unusual.
|
|
Military macaws live in large flocks and can live about 50–60 years in the wild. They can often be heard long before they are seen. They are a very noisy bird making a variety of loud cracking and shrieking sounds, including a loud kraa-aak. Military macaw activity has been observed most frequently in the morning and the evening meaning they are most likely a crepuscular species.
|
|
The positioning of the egret's eyes allows for binocular vision during feeding, and physiological studies suggest that the species may be capable of crepuscular or nocturnal activity. Adapted to foraging on land, they have lost the ability possessed by their wetland relatives to accurately correct for light refraction by water. This species gives a quiet, throaty rick-rack call at the breeding colony, but is otherwise largely silent.
|
|
Wombat in Narawntapu National Park, Tasmania Wombats dig extensive burrow systems with their rodent-like front teeth and powerful claws. One distinctive adaptation of wombats is their backward pouch. The advantage of a backward-facing pouch is that when digging, the wombat does not gather soil in its pouch over its young. Although mainly crepuscular and nocturnal, wombats may also venture out to feed on cool or overcast days.
|
|
It fearlessness, weak flight and distinctive markings all indicate that it is a protected butterfly, which is peculiar considering that its host plants are not known to contain any sequestrable toxins. There is a mention in literature of the species being found at lights at night, however such phenomena are usually restricted to species that are crepuscular and this occurrence may be incidental.Usman, S., 1956. Some insects attracted to light.
|
|
However, like deer, bongos may exhibit crepuscular behaviour. Bongos are both timid and easily frightened; after a scare, a bongo moves away at considerable speed, even through dense undergrowth. Once they find cover, they stay alert and face away from the disturbance, but peek every now and then to check the situation. The bongo's hindquarters are less conspicuous than the forequarters, and from this position the animal can quickly flee.
|
|
The ladder snake is normally active by day, but during the hottest summer months it may be nocturnal, while in the spring months it may be more crepuscular. Its behaviour is said to be more like that of whipsnakes rather than that of rat snakes. It is more aggressive and defensive than most of the species formerly classified alongside it in the genus Elaphe. Defensive signals include hissing and lunging forward with the mouth open.
|
|
Wombats use their rodent-like front teeth and powerful claws to dig extensive burrow systems; they are mainly crepuscular and nocturnal. Wombats are also well known for their backwards facing pouches. Also among this group is the marsupial lion, which went extinct after the arrival of aboriginals, and was one of the few carnivorous vombatiforms. The Phalangeriformes includes possums and is a diverse group of arboreal marsupials, including six families and 26 species.
|
|
The Japanese forest rat snake can be found surface active at any hour, but they most often show crepuscular activity patterns. It may completely cease surface activity from mid-late summer when conditions become too hot and/or dry. Principal prey items are small rodents, and the snakes often use the rodent burrows for shelter. As the Japanese common name suggests, this species is fossorial, and is normally associated with forested areas.

Harpy fruit bats are found on the Philippine islands of Biliran, Maripipi, Camiguin, Leyte, Southern Luzon, Mindanao, Mindoro, Negros, Cebu, Masbate, and Samar. They reside in primary (old growth), secondary, and lightly disturbed montane forests. Their range in elevation is between sea level and 1,800m, preferring to stay in habitats of "mid-elevation (around 500m)". As with other fruit bats, harpy fruit bats are crepuscular and "roost in trees" instead of caves.

Marbled cats recorded in northeastern India and Kalimantan on Borneo were active by day. The first-ever radio-tracked marbled cat had an overall home range of at an elevation of and was active primarily during nocturnal and crepuscular times. Marbled cats recorded in northeast India were active during the day with activity peaks around noon. Forest canopies probably provide the marbled cat with much of its prey: birds, squirrels and other rodents, and reptiles.
|
|
Visual observation is the obvious means of detecting bats, but of course this can only be done in daylight or crepuscular conditions (i.e., dusk and dawn). Emergence counts are done visually at dusk, using a bat detector for confirmation of species. In lower light conditions a night vision device can be used but the more affordable generation 1 type has a lag time which fails to provide a suitable image of a flying bat.

|
Asian golden cat with a piece of meat Asian golden cats are territorial and solitary. Previous observations suggested that they are primarily nocturnal, but a field study on two radio-collared specimens revealed arrhythmic activity patterns dominated by crepuscular and diurnal activity peaks, with much less activity late at night. In the study, the male's territory was in size and increased by more than 15% during the rainy season. The female's territory was in size.

The music in the game was composed by Yasunori Mitsuda, Shunsuke Tsuchiya and Yuki Harada. The opening theme is Negai Hoshi by Nami Tamaki, and the ending theme is Tenshi no Hashigo ~crepuscular rays~ by Yui Makino. The soundtrack album is released on 3 March 2010 which contains 3 disk. The soundtracks are composed and arranged by Yasunori Mitsuda, Shunsuke Tsuchiya, Yuki Harada, Yoko Shimomura and also Ryfia's Japanese voice actress, Yui Makino.

The bobcat is crepuscular, and is active mostly during twilight. It keeps on the move from three hours before sunset until about midnight, and then again from before dawn until three hours after sunrise. Each night, it moves from along its habitual route. This behavior may vary seasonally, as bobcats become more diurnal during fall and winter in response to the activity of their prey, which are more active during the day in colder weather.

A demonstrated human-biter, Aedes vittatus can transmit yellow fever virus in monkeys in the laboratory and was a suspected vector in the 1940 Nuba Mountain epidemic in Sudan in which an estimated 15,000 human cases and 1,500 deaths were reported. Aedes vittatus is potentially capable of transmitting Zika virus, the causative agent of Zika fever. The adult females have a short crepuscular biting period, with maximum activity between 1800 and 2100 hours.

Its hunting pattern, outside breeding periods and periods of abundant prey, has distinct crepuscular peaks, perhaps corresponding to mouse activity. When hunting, the kite hovers with its body hanging almost vertically, and its head into the wind. Unlike the nankeen kestrel, the black- winged kite shows no obvious sideways movement, even in a strong breeze. One study of a nesting pair noted that the male searched aerially for 82% of the search time.

It is known as the "hog deer" because when it is fleeing from danger, it dashes through underbrush with its head down like a hog instead of jumping over barriers like other deer. These animals are crepuscular, meaning that they are active at sunrise and twilight. They rest during the warmer part of the day and then come out from the undergrowth to forage. Mainly solitary, they sometimes form small herds if left undisturbed.

The lifecycle of mosquitoes in the Aedes genus. This species lays its eggs in holes in trees, cut bamboo, bamboo stumps, and tree forks. In laboratory settings, it was observed that the larvae hatch best at 27 °C and the quantity of water was not a factor in embryonic development but we most often laid within 2 cm of the water surface. Aedes africanus adults are crepuscular feeders, meaning they feed from dusk to dawn.

The New Caledonian rail (Cabalus lafresnayanus) is a large and drab flightless rail that is found on the island of New Caledonia in the Pacific. It is a dull brown above, with grey underparts, and has a yellowish, downward-curving bill. No one knows what it sounds like and it is not known whether it is nocturnal or crepuscular. It most likely was driven to extinction from predation by feral cats, dogs, and pigs.

This endothermy during crepuscular hours allows the use of optimal atmospheric conditions for acoustic communication and reduces chances of predation to a minimum. The species also produces an encounter call used in courtship and maintaining personal space within choruses, behaving aggressively to other males venturing closer than about 50 cm. Choruses may start up at any time of the day, but concentrate their calling in a half-hour period at dawn and dusk.

Karimi's fat-tailed mouse opossum (Thylamys karimii) is a species of opossum in the family Didelphidae. It is endemic to central and northeast Brazil, where it is found in the cerrado and caatinga at elevations from 300 to 1100 m. This opossum is crepuscular and mostly terrestrial; its omnivorous diet includes leaves, insects and small vertebrates. Its head-and-body length is about 95 millimeters, and its tail length is about 72 millimeters.

Barbary sheep Barbary sheep are found in arid mountainous areas where they graze and browse grasses, bushes, and lichens. They are able to obtain all their metabolic water from food, but if liquid water is available, they drink and wallow in it. Barbary sheep are crepuscular - active in the early morning and late afternoon and rest in the heat of the day. They are very agile and can achieve a standing jump over .

The lutrine opossum ("lutrine" means "otter-like" and "crass" meaning "thick, fat" and "cauda" meaning "tail") is a very peculiar opossum, having a long weasel-like body, short legs, small rounded ears, and dense reddish or yellowish fur. Nocturnal and crepuscular, they generally live in grasslands and savannas near water. They are terrestrial but are excellent swimmers and climbers. Genetic and morphological studies indicate that there is a second species, Lutreolina massoia.

The team caught six females and seven males. One female was pregnant and gave birth to six pups. All these 19 caught golden hamsters, together with three wild individuals from the University of Aleppo, were shipped to Germany to form a new breeding stock. Observations of females in this wild population have revealed, contrary to laboratory populations, activity patterns are crepuscular rather than nocturnal, possibly to avoid nocturnal predators such as owls.

The Donets ruffe (Gymnocephalus acerina) is a species of perch native to eastern Europe where it occurs in the basins of the Black Sea and the Sea of Azov. They inhabit freshwater lakes and rivers usually over hard compacted sand. They are predominantly crepuscular and prey mostly on invertebrates (crustaceans, insect larvae, mollusks), rarely on fish. They are inactive during winter months, and usually move to deeper places until the ice melts.

University of Massachusetts, Amherst. The Tehuantepec Jackrabbit is also found in coastal grassy dunes with Opuntia decumbens, Opuntia tehuantepecana, and Sabal mexicana. Home ranges overlap with one or more individuals regardless of sex and age, and home range size is about 50 ha with core areas of 9 ha for adult jackrabbits. The Tehuantepec jackrabbit is nocturnal and crepuscular, and during the diurnal hours it rests in forms under bushes or grasses.

Thorold's deer is a crepuscular animal, normally living in herds of at least 10 individuals. Outside of the breeding season, males and females usually travel separately. Historically, herds containing hundreds of such deer were reported, but today, herds of over 100 individuals are rare. Like wapiti, they are predominantly grazers; they feed on a wide range of available plants, especially grasses and sedges, but including some larger plants such as rhododendrons and willows.

A 5-month-old calf and its 17-month-old cousin in a sanctuary in Laos Elephants are crepuscular. They are classified as megaherbivores and consume up to of plant matter per day. They are generalist feeders, and are both grazers and browsers. They are known to feed on at least 112 different plant species, most commonly of the order Malvales, as well as the legume, palm, sedge and true grass families.

In flight In flight In Piraju, São Paulo, Brazil Hunting occurs mostly at night, but this owl is known to be diurnal and crepuscular as well. Its daylight hunting seems to coincide with the high- activity periods of voles, its preferred prey. It tends to fly only feet above the ground in open fields and grasslands until swooping down upon its prey feet-first. Several owls may hunt over the same open area.

The females of many species produce a release call, and Xenopus laevis females produce an additional call when sexually receptive and soon to lay eggs. The Xenopus species are also active during the twilight (or crepuscular) hours. During breeding season, the males develop ridge-like nuptial pads (black in color) on their fingers to aid in grasping the female. The frogs' mating embrace is inguinal, meaning the male grasps the female around her waist.

Steam phase eruption of Castle Geyser in Yellowstone National Park casts a shadow on its own steam. Crepuscular rays are also visible. The farther the distance from the object blocking the light to the surface of projection, the larger the silhouette (they are considered proportional). Also, if the object is moving, the shadow cast by the object will project an image with dimensions (length) expanding proportionally faster than the object's own rate of movement.

Ring- necked snakes are primarily nocturnal or highly crepuscular, though some diurnal activity has been observed. Individuals are sometimes found during the day, especially on cloudy days, sunning themselves to gain heat. Yet, most individuals lie directly under surface objects warmed in the sun and use conduction with that object to gain heat. Though ring-necked snakes are highly secretive, they do display some social structure, but the exact social hierarchies have never been evaluated.

|
Four bee families (Andrenidae, Colletidae, Halictidae, and Apidae) contain some species that are crepuscular. Most are tropical or subtropical, but some live in arid regions at higher latitudes. These bees have greatly enlarged ocelli, which are extremely sensitive to light and dark, though incapable of forming images. Some have refracting superposition compound eyes: these combine the output of many elements of their compound eyes to provide enough light for each retinal photoreceptor.

|
Night snakes are known to be both crepuscular (most active at dawn and dusk), and nocturnal. They are usually seen at night while crossing roads, but can be found under rocks, boards, dead branches and other surface litter during the day. Night snakes hibernate during the winter months, and are known to aestivate during periods of the summer. They are generally most active from April to October, with peaks of activity usually occurring in June.

Hedgehogs are mostly nocturnal. Hedgehogs and sugar gliders are just two of the many nocturnal species kept as (exotic) pets. Cats have adapted to domestication so that each individual, whether stray alley cat or pampered housecat, can change their activity level at will, becoming nocturnal or diurnal in response to their environment or the routine of their owners. Cats normally demonstrate crepuscular behavior, bordering nocturnal, being most active in hunting and exploration at dusk and dawn.
|
|
The species is nocturnal and partly diurnal or active at night and daytime, whether it is crepuscular is not known. The species breeds during May–July and gives birth in July–August after 28–32 days gestation to 6–8 joeys. In the inland areas, mating occurs one month earlier, but the reason is not known. Few females survive a second year and all males do not live long past the mating period (Wilson etal. 1986.).

This species is large in size with long, pointed ears and a distinct coat coloration. The antelope jackrabbit has a white belly, light grey sides, a back peppered with black, and orange coloration on the neck and chest. It is similar to species like the black-tailed jackrabbit and white-sided jackrabbit. It is most active during twilight (crepuscular) and during the night (nocturnal), but can be active during the day when conditions are favorable (heavy cloud coverage).

|
A solitary, mostly terrestrial nocturnal predator, the western quoll is most active around dusk (crepuscular) when it hunts. It moves swiftly on the ground, climbs efficiently, and may dig or occupy existing burrows. During the day it seeks refuge in hollow logs or earth burrows as dens, and saves energy by lowering its body temperature in its sleep. The western quoll is at the top of the food chain, and depends on resource abundance and a healthy ecosystem.
|
|
This species prefers gravel banks along rivers or large lakes, and also beaches. It is mainly nocturnal or crepuscular like other stone-curlews, but can frequently be seen foraging during the day, moving slowly and deliberately, with occasional short runs. It tends to be wary and flies off into the distance ahead of the observer, employing powerful, rather stiff wingbeats. The call is a wailing whistle, given mainly at night, as with other birds in this family.

These are arid-adapted perennials with thick taproots which are usually compact and low to the ground or slightly ascending. An individual plant may have cleistogamous (unopening and self-pollinating) flowers as well as opening flowers which are usually nocturnal as a water-saving adaptation and are pollinated by night-flying or crepuscular insects such as hawkmoths. Flowers are usually white, sometimes yellow. These plants are native to the Chihuahuan and Sonoran Deserts of Mexico and the United States.

The northern hawk-owl or northern hawk owl (Surnia ulula) is a medium-sized true owl of the northern latitudes. It is non-migratory and usually stays within its breeding range, though it sometimes irrupts southward. It is one of the few owls that is neither nocturnal nor crepuscular, being active only during the day. This is the only living species in the genus Surnia of the family Strigidae, the "typical" owls (as opposed to barn owls, Tytonidae).

Telsons of H. anomala and M. diluviana. Mature individuals reach in length; females are slightly larger than males. The species can be ivory-yellow in colour or translucent, but exhibits pigmented red chromatophores in the carapace and telson. The intensity of colouration, believed to be associated with the species' crepuscular behaviour, varies with contraction or expansion of the chromatophores in response to light and temperature conditions; in shaded areas, individuals tend to have a deeper red colour.

California voles are crepuscular or nocturnal. However, they spend much of their time below ground, using burrows connected by above-ground runways they use to find food. Home ranges are relatively small, with the animals rarely venturing far from their burrows; averages of for males and for females have been reported. The larger ranges of males overlap with the ranges of several nearby females, but they are generally aggressive only towards other nearby males, clawing and biting any intruders.
|
|
Chinchillas are either of two species (Chinchilla chinchilla and Chinchilla lanigera) of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations of up to . Historically, chinchillas lived in an area that included parts of Bolivia, Peru, Argentina, and Chile, but today, colonies in the wild are known only in Chile.

|
Selection pressures, such as high predatory activity or low food may require animals to change their behaviours to adapt. An animal changing the time of day at which it carries out significant tasks (e.g., mating and/or foraging) is recognized as one of these adaptive behaviours. For example, human activity, which is more predominant during daylight hours, has forced certain species (most often larger mammals) living in urban areas to shift their schedules to crepuscular ones.

|
They dig and live in burrows with steep tunnels as deep as six feet underground. In the wild, Roborovski hamsters are crepuscular, being most active at dawn and dusk. The Roborovski hamster has been found to be more common in the southern area of its distribution range, in areas such as Yulin, Shaanxi, China. It has been reported as a common sighting by locals in this city and in the sand dunes of the Ordos desert.

These wasps prey almost exclusively on tarantulas of the family Theraphosidae. In Texas, the preferred prey is Aphonopelma hentzi. The female wasps hunt in a crepuscular pattern, avoiding the intense daytime sun, by flying low over the ground, detecting their prey using vision or scent, possibly detecting the occupied burrows by the scent of the silk curtain the spider weaves over the entrance. The females may also hunt on the ground, flicking her wings and antennae quite intensively.

Comparison of an owl (left) and hawk (right) remex. The serrations on the leading edge of an owl's flight feathers reduce noise Owl eyes each have nictitating membranes that can move independently of each other, as seen on this spotted eagle-owl in Johannesburg, South Africa. Most owls are nocturnal, actively hunting their prey in darkness. Several types of owls, however, are crepuscular—active during the twilight hours of dawn and dusk; one example is the pygmy owl (Glaucidium).

|
Due to its extremely reclusive habits, little is known about the behaviour of African golden cats. They are solitary animals, and are normally crepuscular or nocturnal, although they have also been observed hunting during the day, depending on the availability of local prey. African golden cats are able to climb, but hunt primarily on the ground. They mainly feed on tree hyrax, rodents, but also hunt birds, small monkeys, duikers, young of giant forest hog, and small antelope.

The red fox is the main quarry of European and American fox hunts. The red fox (Vulpes vulpes) is the normal prey animal of a fox hunt in the US and Europe. A small omnivorous predator, the fox lives in burrows called earths, and is predominantly active around twilight (making it a crepuscular animal). Adult foxes tend to range around an area of between square kilometres () in good terrain, although in poor terrain, their range can be as much as .

|
They may have been more agile than their prey items, but were probably inertial homeotherms rather than endotherms as contemporary therocephalians and cynodonts, and thus were probably comparatively less active. Though gorgonopsians were able to maintain a rather high body temperature, it is unclear if they would have also had fur, sweat glands, or whiskers. They had an overall more reptilian than mammalian brain. Most species may have been predominantly diurnal, active during the day, though some could have been crepuscular or nocturnal.

The Cape cobra is a diurnal species and actively forages throughout the day. During very hot weather it may become crepuscular, but is rarely if ever observed during the hours of darkness. It is a terrestrial snake, but will readily climb trees and bushes, and shows considerable agility in for example systematically robbing the nests of the sociable weaver. When not active, it hides in holes or under ground cover, such as brush piles, often remaining in the same retreat for some time.

This beetle lives in desert habitat, where it feeds on cactus plants, especially species of prickly pear (Opuntia) and cholla (Cylindropuntia). The beetle is a threat to several rare species of cactus, including the Mojave fishhook cactus (Sclerocactus polyancistrus), Wright's fishhook cactus (Sclerocactus wrightiae), Mesa Verde cactus (Sclerocactus mesae-verdae), Winkler's pincushion cactus (Pediocactus winkleri), and San Rafael cactus (Pediocactus despainii). The adult beetle is nocturnal or crepuscular. It emerges and climbs cactus plants at dusk to feed during the night.

Anticrepuscular rays, or antisolar rays, are meteorological optical phenomena similar to crepuscular rays, but appear opposite of the Sun in the sky. Anticrepuscular rays are essentially parallel, but appear to converge toward the antisolar point, the vanishing point, due to a visual illusion from linear perspective. Anticrepuscular rays are most frequently visible around sunrise or sunset. This is because the atmospheric light scattering that makes them visible (backscattering) is larger for low angles to the horizon than most other angles.

The eastern grey kangaroo is predominantly a grazer, and eats a wide variety of grasses, whereas some other species such as the red kangaroo include significant amounts of shrubs in their diets. Smaller species of kangaroos also consume hypogeal fungi. Many species are nocturnal, and crepuscular, usually spending the hot days resting in shade, and the cool evenings, nights and mornings moving about and feeding. Because of its grazing habits, the kangaroo has developed specialized teeth that are rare among mammals.

|
Mating fights between males occur, but are rare, and aggression avoidance behavior has been observed in the wild. When it occurs, conflict is typically over territory: a male's range may encompass that of two or three females, and he will not tolerate intrusions by other adult males. The jaguar is often described as nocturnal, but is more specifically crepuscular (peak activity around dawn and dusk). Both sexes hunt, but males travel farther each day than females, befitting their larger territories.

M. ikaheca is a thick-bodied, smooth-scaled snake that grows up to long. It has small eyes that are typical of other semi-fossorial burrowing snakes, and is either nocturnal or crepuscular. In common with most other elapids, M. ikaheca is oviparous. The name ikaheca means "land eel" in a local West Papuan dialect, indicating the snake's preference for damp or semi-aquatic habitats, such as swamps, creeks, wetlands, low-lying rainforest, and piles of discarded vegetation debris, i.e.

Bat hawks also show very rapid ingestion rates, taking on average 6 seconds for the prey to reach the stomach after capture. The bat hawk is crepuscular and hunts at dusk. They feed on the wing and swallow their prey whole. This feeding habit has resulted in the evolution of an unusually large gape, the largest of any raptor relative to body size, and is more similar to that of insectivorous birds which feed on the wing such as swallows, swifts and nightjars.

|
The golden-crowned sifaka is primarily active during the day (diurnal), but researchers have witnessed activity in the early morning and evening (crepuscular) during the rainy season (November through April). In captivity, it has been observed feeding at night, unlike captive Verreaux's sifakas. It travels between per day, an intermediate range compared to other sifakas of the eastern forests. The golden-crowned sifaka can be observed feeding and resting higher in the canopy during the dry season (May through October).

Their third album, "Limb Shop" (released on Raging Planet, Base records, Soopa and Radon in 2006), was produced by Jonathan Uliel Saldanha, moving the sound of the group a step deeper into an abstract landscape of field recordings, brute noise and crepuscular heavy funk and dub. Finally freed from the "track" shape which prevailed on the previous albums, Limb Shop is a 60 minute piece on disfiguration, real and fictional amputation vs. prosthesis and inner-space science fiction turned into sound.

This species has been called one of the rarest carnivorans in the world. With a few exceptions, the majority of records of G. grandidieri come from a narrow zone at the western edge of the Mahafaly Plateau in the Parc National de Tsimanampetsotsa, making it the Madagascan carnivore with the smallest range. Nocturnal and crepuscular, this species lives in pairs which produce one offspring a year, in the summer. They hunt primarily by searching through ground litter and in rock crevices.

Wombats, on the other hand, live on the ground and feed on grasses, sedges and roots. Wombats use their rodent- like front teeth and powerful claws to dig extensive burrow systems; they are mainly crepuscular and nocturnal. The Phalangerida includes six families and 26 species of possum and three families with 53 species of macropod. The possums are a diverse group of arboreal marsupials and vary in size from the little pygmy possum, weighing just 7 g,Menkhorst and Knight, p. 92.

Marleyimyia xylocopae is a species of bee fly from South Africa that has a similarity to the patterning of a carpenter bee Xylocopa flavicollis found in the region. The species is considered to be distinctive and only one of three within the genus Marleyimyia. The other members of the genus are Marleyimyia goliath described from Peninsular Malaysia and M. natalensis from southern Africa. Members in the genus have been presumed to be crepuscular or nocturnal but this species was found to be diurnal.

Pteropus bats are dichromatic, possessing two kinds of cone cells. The other three genera, with their lack of S-cones, are monochromatic, unable to see color. All genera had very high densities of rod cells, resulting in high sensitivity to light, which corresponds with their nocturnal activity patterns. In Pteropus and Rousettus, measured rod cell densities were 350,000–800,000 per square millimeter, equal to or exceeding other nocturnal or crepuscular animals such as the house mouse, domestic cat, and domestic rabbit.

Amphibians were more considerably more popular in the diet in western part of range, comprising 10.5% of known studies against 4.4% in the east. In total, well over 20 amphibian species have been identified in the foods of barred owls and amphibians collectively can make up to 24.5% of the local diet (as was reported in Alberta). While salamanders and newts are probably often visually discerned while scanning the forest floor, many frogs are probably hunted down by sound during their crepuscular choruses.

Low platypus numbers in northern Australia are possibly due to predation by crocodiles. The introduction of red foxes in 1845 for hunting may have had some impact on its numbers on the mainland. The platypus is generally regarded as nocturnal and crepuscular, but individuals are also active during the day, particularly when the sky is overcast. Its habitat bridges rivers and the riparian zone for both a food supply of prey species, and banks where it can dig resting and nesting burrows.
|
|
When observed in environments where there is little or no human activity, these same species often do not exhibit this temporal shift. It may be argued that if the goal is to avoid human activity, or any other diurnal predator's activity, a nocturnal schedule would be safer. However, many of these animals depend on sight, so a matutinal or crepuscular schedule is especially advantageous as it allows animals to both avoid predation, and have sufficient light to mate and forage.

The white-rumped shama is shy and somewhat crepuscular but very territorial. The territories include a male and female during the breeding season with the males defending the territory averaging 0.09 ha in size, but each sex may have different territories when they are not breeding. In South Asia, they breed from January to September but mainly in April to June laying a clutch of four or five eggsWhistler, H (1949) Popular handbook of Indian birds. Gurney and Jackson. p.

Like most nightjars, Bates's nightjar is crepuscular and nocturnal. It roosts on the ground, in clearings or on paths, or several metres up perched on a liana. Forages for prey such as mantises, crickets, grasshopper, beetles and moths over and within the forest canopy, over clearingsand along the edges of riverine forest. It does not build a nest and the single egg is laid directly onto the bare ground or among the leaf litter, nest site are sometimes on paths or trails.

While grasses and forbs are preferred, red kangaroos will also eat certain species of chenopods, like Bassia diacantha and Maireana pyramidata, and will even browse shrubs when its favoured foods are scarce. However, some perennial chenopods, such as round-leaf chenopod Kochia are avoided even when abundant. At times, red kangaroos congregate in large numbers; in areas with much forage, these groups can number as much as 1,500 individuals. Red kangaroos are mostly crepuscular and nocturnal, resting in the shade during the day.

Worker grooming herself M. nigriceps ants are crepuscular and nocturnal foragers, searching for food during the night. Workers are found foraging on Eucalyptus trees and is sympatric with many species. Adults are nectarivores, feeding on sweet liquids from plants and the larvae are carnivorous, feeding on captured invertebrates and other ants such as Camponotus workers and males. Cockroaches, such as Platyzosteria castanea and Platyzosteria ruficeps, can repel attacks by M. nigriceps by discharging a secretion that disorientates the attacking workers.

The golden mouse is mainly nocturnal, crepuscular and arboreal, although many live on the ground as well. Its peak activity occurs around 3 to 4 hours before dawn. Golden mice move quickly and easily and are able to use their prehensile tails for balance while climbing trees, to hang from branches, and to anchor themselves to a tree limb while they sleep. Newborn golden mice are fairly coordinated at birth; however, they have a tendency to remain quietly in one spot.

Due to its wide range, it has many names including puma, mountain lion, panther, painter and catamount. The cougar is the second-largest cat in the New World after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. The cougar is more closely related to smaller felines, including the domestic cat, than to any species of subfamily Pantherinae, of which only the jaguar is extant in the Americas.

One of the reasons that (cathemeral) lions prefer to hunt at night is to conserve water. Many plant species native to arid biomes have adapted so that their flowers only open at night when the sun's intense heat cannot wither and destroy their moist, delicate blossoms. These flowers are pollinated by bats, another creature of the night. Climate-change and the change in global temperatures has led to an increasing amount of diurnal species to push their activity patterns closer towards crepuscular or fully nocturnal behavior.

Platypleura divisa (Germar, 1834), is an African cicada first described by Ernst Friedrich Germar, entomologist and professor of mineralogy at Halle, who also studied beetles. The genus Platypleura occurs widely across Africa and southern Asia. Some of the South African species are remarkable for their endothermic thermoregulation that enables crepuscular signalling, an adaptation that reduces risk of predation and enables a greater range for their calls. In field experiments their maximum body temperature while calling at dusk, was measured at 22 °C above ambient temperature.

After mating, the male leaves the female alone to raise the cub. Pandas were thought to fall into the crepuscular category, those who are active twice a day, at dawn and dusk; however, Jindong Zhang found that pandas may belong to a category all of their own, with activity peaks in the morning, afternoon and midnight. Due to their sheer size, they can be active at any time of the day.Pandas Live by a Different Rhythm published on 08/07/2015 by Michigan State Univ.

Ferrets spend 14–18 hours a day asleep and are most active around the hours of dawn and dusk, meaning they are crepuscular If they are caged, they should be taken out daily to exercise and satisfy their curiosity; they need at least an hour and a place to play. Retrieved 2020-09-07. Unlike their polecat ancestors, which are solitary animals, most ferrets will live happily in social groups. They are territorial, like to burrow, and prefer to sleep in an enclosed area.

Twilight should not be confused with auroras, which can have a similar appearance in the night sky at high latitudes. By analogy with evening twilight, the word twilight is also sometimes used metaphorically, to imply that something is losing strength and approaching its end. For example, very old people may be said to be "in the twilight of their lives". The collateral adjective for twilight is crepuscular, which may be used to describe the behavior of animals that are most active during this period.

Isoxys was abundant in tropical seas, and may have had a global distribution. Eyes of different specimens appear to have been adapted to different light intensities; one specimen of I. auritus was either crepuscular in shallow water, or lived in waters around 140 m below the sea surface; whereas another was morphologically adapted to a diurnal light intensity in shallow waters. It is likely that Isoxys was a visual predator that hunted swimming above the seafloor. It had powerful prehensile frontal appendages and large spherical eyes.

A skunk in Ontario, Canada Skunks are crepuscular and solitary animals when not breeding, though in the colder parts of their range, they may gather in communal dens for warmth. During the day they shelter in burrows, which they can dig with their powerful front claws. Males and females occupy overlapping home ranges through the greater part of the year, typically for females and up to for males. Skunks are not true hibernators in the winter, but do den up for extended periods of time.

Jackals are crepuscular, most active at dawn and dusk. Their most common social unit is a monogamous pair, which defends its territory from other pairs by vigorously chasing intruding rivals and marking landmarks around the territory with their urine and feces. The territory may be large enough to hold some young adults, which stay with their parents until they establish their own territories. Jackals may occasionally assemble in small packs, for example, to scavenge a carcass, but they normally hunt either alone or in pairs.

Though they are by no means generally regarded as serious pests, their depredations can be unwelcome to grain farmers and horticulturists when their population happens to be high. Rhabdomys are important prey items for many species of snake, and for small to medium-sized carnivores such as the caracal, serval, wildcat and black-footed cat, jackal, and several species of mongoose. They also are major food items for several species of birds of prey. Even owls take advantage when they catch the mice in crepuscular activity.

The life history of E. rosaliae is virtually unknown (Price 1990b). The species seems to be nocturnal or crepuscular and may be surface active during daylight hours under suitable conditions (Ottley and Jacobsen 1983). Nothing is known about reproduction or growth except that clutches with an unspecified number of eggs have been laid in captivity (Price 1990b). The few data on diet and behavior are based on captive specimens and are difficult to interpret in the absence of data on this snake under field conditions.

Corydalus cornutus - MHNT Megaloptera is an order of insects. It contains the alderflies, dobsonflies and fishflies, and there are about 300 known species. The order's name comes from Ancient Greek, from mega- (μέγα-) "large" + pteryx (πτέρυξ) "wing", in reference to the large, clumsy wings of these insects. Megaloptera are relatively unknown insects across much of their range, due to the adults' short lives, the aquatic larvae's often-high tolerance of pollution (so they are not often encountered by swimmers etc.), and the generally crepuscular or nocturnal habits.

The coral catshark can usually be found resting and hidden in daytime. The elongated body of the coral catshark allows it to move into and through small spaces in the reef environment, though it does not "crawl" using its pectoral and pelvic fins like the epaulette shark (Hemiscyllium ocellatum). It is primarily crepuscular and nocturnal, with active foraging activity beginning in the afternoon and ending before sunrise. During the day, it generally hides under shelter such as reef overhangs or sunken logs, either singly or in groups.

The common nighthawk (Chordeiles minor) is a medium-sized crepuscular or nocturnal bird of the Americas within the nightjar family, whose presence and identity are best revealed by its vocalization. Typically dark (grey, black and brown), displaying cryptic colouration and intricate patterns, this bird is difficult to spot with the naked eye during the day. Once aerial, with its buoyant but erratic flight, this bird is most conspicuous. The most remarkable feature of this aerial insectivore is its small beak that belies the massiveness of its mouth.

The European nightjar (Caprimulgus europaeus), common goatsucker, Eurasian nightjar or just nightjar, is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and the Palearctic to Mongolia and Northwestern China. The Latin generic name refers to the old myth that the nocturnal nightjar suckled goats, causing them to cease to give milk. The six subspecies differ clinally, the birds becoming smaller and paler towards the east of the range. All populations are migratory, wintering in sub-Saharan Africa.

Examination of brain endocasts has shown that both A. maximus and A. hildebrandi had greatly reduced optic lobes, similar to those of their closest living relatives, the kiwis, and consistent with a similar nocturnal lifestyle. The optic lobes of Mullerornis were also reduced, but to a lesser degree, suggestive of a nocturnal or crepuscular lifestyle. A. maximus had relatively larger olfactory bulbs than A. hildebrandi, suggesting that the former occupied forested habitats where the sense of smell is more useful while the latter occupied open habitats.

Characteristics of rubber boas behavior also set them apart from other snakes. Rubber boas are considered one of the most docile of the boa species and are often used to help people overcome their fear of snakes. Rubber boas are known to never strike at or bite a human under any circumstances but will release a potent musk from their vent if they feel threatened. They are primarily nocturnal and likely crepuscular (active during dawn and dusk) which partially contributes to how rarely they are encountered.

A cheetah hunting a Thomson's gazelle Cheetahs are diurnal animals (active mainly during the day), whereas the stronger apex predators, such as hyenas, African leopards and lions are nocturnal (active mainly at night). Hunting is the major activity throughout the day; peaks are observed during dawn and dusk indicating crepuscular tendencies. Groups rest in grassy clearings after dusk, though males and juveniles often roam around at night. In Kenya, cheetahs of the Masai Mara hunt after sunset to escape the high temperatures of the day.

Pronycticebus neglectus possessed what appears to be a grooming claw on the second digit of each foot like modern strepsirhines (Fleagle, 1999) and had a dental formula of 2:1:4:3. Pronycticebus neglectus has a petrosal bulla and a postorbital bar. Pronycticebus neglectus may have been a nocturnal or a crepuscular species, which is suggested by a relatively large orbital size. Pronycticebus neglectus has a relatively large baculum for a species of its size, which had an average body mass of 825 grams.

Females are usually sexually mature at two months of age and the gestation period is typically 20 days. Campbell's dwarf hamster is crepuscular, along with all species of Phodopus and is active throughout the year. Campbell's dwarf hamsters are omnivores, and so feed on both plant and insect material. Campbell's dwarf hamster inhabits burrows with four to six horizontal and vertical tunnels in the steppes and semi deserts of central Asia, the Altai mountains, autonomous areas of Tuva and the Hebei province in northeastern China.

Animals active during twilight are crepuscular, those active during the night are nocturnal, and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinators are foraging. For example, sunflowers open during the day to attract bees, whereas the night-blooming cereus opens at night to attract large sphinx moths.

Sutro Tower casts a 3-dimensional fog shadow Shadows are cast through fog in three dimensions. The fog is dense enough to be illuminated by light that passes through gaps in a structure or tree, but thin enough to let a large quantity of that light pass through to illuminate points further on. As a result, object shadows appear as "beams" oriented in a direction parallel to the light source. These voluminous shadows are created the same way as crepuscular rays, which are the shadows of clouds.

While most pups will survive to be weaned, Guiler reported that up to three fifths of devils do not reach maturity. As juveniles are more crepuscular than adults, their appearance in the open during summer gives the impression to humans of a population boom. A study into the success of translocated devils that were orphaned and raised in captivity found that young devils who had consistently engaged with new experiences while they were in captivity survived better than young who had not. Embryonic diapause does not occur.

Sambar attacked by dholes, Bandipur National Park Two stags locking antlers Tiger attacking a sambar in Ranthambore Sambar are nocturnal or crepuscular. The males live alone for much of the year, and the females live in small herds of up to 16 individuals. Indeed, in some areas, the average herd consists of only three or four individuals, typically consisting of an adult female, her most recent young, and perhaps a subordinate, immature female. This is an unusual pattern for deer, which more commonly live in larger groups.

Hunting nocturnal or crepuscular, this bird can target its prey and dive to the ground, penetrating its talons through snow, grass or brush to seize small creatures with deadly accuracy. Compared to other owls of similar size, the barn owl has a much higher metabolic rate, requiring relatively more food. Weight for weight, barn owls consume more rodents—often regarded as pests by humans—than possibly any other creature. This makes the barn owl one of the most economically valuable wildlife animals for agriculture.

Early in the novel, when Alice travels via aircraft she has an epiphany as to the significance of modern technology. Upon entering the plane, Alice says “I feel like God,” suggesting a feeling of spiritual enlightenment which arises through the opportunities modernity presents. Australian literary critic, Lydia Wevers, argues that Jones’ novel is deep with postmodern ironies and the ironies of modernity. Wevers highlights that the wonder and romance of technology, in Jones’ text, is overshadowed by its "crepuscular gloom" and the "solipsistic reveries" of passenger experience.

Ultrasonography of the uterine pregnancy of a roe deer in Bulgaria In order to mitigate risk while foraging, roe deer remain within refuge habitats (such as forests) during the day. They are likelier to venture into more open habitats at night and during crepuscular periods when there is less ambient activity. Similarly, roe deer are more likely to be spotted in places with nearby forests to retreat to if there is a perceived threat. The roe deer attains a maximum lifespan (in the wild) of 10 years.

Larva and pupa This butterfly is diurnal.Vane-Wright and de Jong (2003) (see TOL web pages on genus Bibasis genus Burara in the Tree of Life Web Project) state that Bibasis contains just three diurnal species, of which sena remains in Bibasis due to its diurnal activity, while the crepuscular remainder having been removed to Burara. The species now shifted to Burara are morphologically and behaviorally distinct from Bibasis, within which many authors have formerly included them. It is confined to heavy jungle of low elevations, typically up to .

The elegant fat-tailed mouse opossum (Thylamys elegans), also known as the Chilean mouse opossum, is an opossum from central Chile. The type species of Thylamys, it was first described by English naturalist George Robert Waterhouse in 1839. This medium-sized opossum is characterized by black rings around the eyes, white limbs, gray to light brown coat, lighter flanks and underbelly and a thick long tail covered with hairs. It is crepuscular (active mainly around twilight) and lives in nests in tree hollows or under rocks and roots.

Groups of Java mouse-deer are commonly referred to as “herds,” while females are termed “does,” “hinds,” or “cows.” Males are referred to as either “bucks,” “stags,” or “bulls,” and their young are commonly called “fawns,” or “asses”. It was previously believed that Java mouse-deer were nocturnal, but more recent studies have shown that they are neither truly nocturnal nor diurnal, but instead crepuscular, meaning they prefer to be active during the dim light of dawn and dusk. This behavior has been observed in both wild and captive Java mouse-deer.

Some wild cat species are adapted to forest habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acinonychinae, differing from each other by the ossification of the hyoid apparatus and by the cutaneous sheaths which protect their claws. This concept has been revised following developments in molecular biology and techniques for analysis of morphological data.

The water from hot springs in non-volcanic areas is heated in this manner. Steam Crepuscular rays at Mammoth Hot Springs In active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and periodically erupts in a jet above the surface of the Earth, it is called a geyser.

Both the traps using visual cues and the control traps, which were empty or contained only a rock, yielded similar results. Juvenile specimens Findings of the study suggest that, particularly during nocturnal and crepuscular periods, attempting to attract specimens using only visual cues by resting or slow-moving fish is not enough to attract Gnathia marleyi. However, using only olfactory cues will attract this species. As a side benefit, the traps engineered for use in this study provide a new method that can be used to sample free-living gnathiid isopods.

Vegetation pile drying on rocks for subsequent storage, Little Cottonwood Canyon, Utah American pika with mouthful of dried grass, Sequoia National Park, California Pikas are diurnal or crepuscular, with higher-elevation species generally being more active during the daytime. They show their peak activity just before the winter season. Pikas do not hibernate, so they generally spend time during the summer collecting and storing food they will eat over the winter. Each rock-dwelling pika stores its own "haypile" of dried vegetation, while burrowing species often share food stores with their burrow mates.

Standing at the vertical edge of a rock cliff in Pangolakha Wildlife Sanctuary An individual walking on snow in Pangolakha Wildlife Sanctuary Himalayan goral often form small bands of four to twelve individuals, although they are also known to pair off or, especially in the case of older males, be solitary. The animal is crepuscular, being most active in the early morning and late evening. After a morning meal, it often drinks and then rests on a rock ledge through the day. It feeds on leaves and associated softer parts of plants, mainly grasses.

The larvae may girdle a root, thereby causing its death, or the lesions may be only partial, allowing the root to continue functioning, albeit with some deformity. The subterranean habitat of the larvae generally provides protection from predation, but the larvae are sometimes parasitised by tachina flies. The parasitoid larvae of the tachinid Rutilotrixa diversa, usually hosted by scarab beetles, have been discovered infecting A. latipennis. Adult A. latipennis are crepuscular and males are strongly attracted to lights, forming leks at dusk, most notably after rains in autumn and late summer.

The white-breasted waterhen (Amaurornis phoenicurus) is a waterbird of the rail and crake family, Rallidae, that is widely distributed across South and Southeast Asia. They are dark slaty birds with a clean white face, breast and belly. They are somewhat bolder than most other rails and are often seen stepping slowly with their tail cocked upright in open marshes or even drains near busy roads. They are largely crepuscular in activity and during the breeding season, just after the first rains, make loud and repetitive croaking calls.

View of dorsal/ventral side E. schrenckii feeds primarily on small mammals, birds, and bird eggs. It is often found in wetlands, but also found in a wide variety of mainly moist environments such as scrub land, farmland, river banks, swamp land, gardens, stones, log piles, forests, and up in trees. The Manchurian black water snake is an excellent swimmer (hence one common name) and is a very good climber, as it is semi- arboreal. This snake is believed to be mostly crepuscular (active only at dawn and dusk).

Most Anopheles mosquitoes are crepuscular (active at dusk or dawn) or nocturnal (active at night). Some feed indoors (endophagic), while others feed outdoors (exophagic). After feeding, some blood mosquitoes prefer to rest indoors (endophilic), while others prefer to rest outdoors (exophilic), though this can differ regionally based on local vector ecotype, and vector chromosomal makeup, as well as housing type and local microclimatic conditions. Biting by nocturnal, endophagic Anopheles mosquitoes can be markedly reduced through the use of insecticide-treated bed nets or through improved housing construction to prevent mosquito entry (e.g.

The younger fish are less site faithful than the oldfeer individuals and will move greater distances and this may be because their diet changes as they mature. The juveniles are more diurnal as zooplankton are more abundant during the day and their small size means they are subjected to greater predation so they take sanctuary among the kelp during. Sub-adults are more active at night and have a more diverse diet with their preferred prey being more active at night. As adults, kelp bass are fish eaters and are crepuscular feeder.

Red river hog at Durrell Wildlife Park (Jersey) The species is omnivorous, eating mainly roots and tubers, and supplements its diet with fruit, grasses, herbs, eggs, dead animal and plant remains, insects, and lizards. It uses its large muzzle to snuffle about in the soil in search of food, as well as scraping the ground with their tusks and fore-feet. They can cause damage to agricultural crops, such as cassava and yams. Red river hogs are often active during the day, but are primarily nocturnal or crepuscular.

Found in mountainous regions at altitudes up to 1000 m, they prefer cooler climates, with an average temperature of 20-25°C. Sometimes, they are found on roadsides, in straw and grass, in rice fields, and even in and around homes. In Vietnam, their preferred habitat is described as forests of bamboo and tree ferns, with clearings, where the forest floor is covered with rotting vegetation, with plenty of rock outcroppings and many open and subterranean streams. The species is crepuscular, and prefers very moist environments for shelter.

Another well-represented species was the prairie vole (Microtus ochrogaster), which were the primary food, making up 26.4% of a sample of 1322, in eastern Kansas. While crepuscular in primary feeding activity, voles are known to be active both day and night, and so are reliable food for hawks than most non-squirrel rodents, which generally are nocturnal in activity. Indeed, most other microtine rodents are largely inaccessible to red-tailed hawks due to their strongly nocturnal foraging patterns, even though 24 species outside of voles and lemmings are known to be hunted.

Iolanda Malamen, " 'Lemnul lui Hristos' a fost un dar", in Ziua, April 5, 2008 Several texts by Annemarie Podlipny-Hehn, including a monograph, deal with her husband's work and its context. Discussing these writings, Cornel Ungureanu writes: "To understand the Austro-Hungarian empire with its left-wing movements, to understand the crepuscular art of Central Europe, Mrs. Podlipny shows, is impossible unless we carefully follow the evolution of esteemed Timoșoarans, among whom the most important one in her studies is still Julius Podlipny."

N. cloacella is a widespread species, found all across western Eurasia and North America, where it has recently been recorded from British Columbia.Shared but overlooked: 30 species of Holarctic Microlepidoptera revealed by DNA barcodes and morphology It is reportedly absent from France, but given that it occurs in all surrounding countries, this is unlikely to be correct. Its preferred habitat is woodland with a large amount of dead trees. The crepuscular adults are on the wing throughout the summer and are typically encountered at dusk but sometimes can be seen earlier in the day.

Those observations, made in the twentieth century, may have been atypical as they were of a species already under the stresses that would soon lead to its extinction. Some behavioural characteristics have been extrapolated from the behaviour of its close relative, the Tasmanian devil. The thylacine was a nocturnal and crepuscular hunter, spending the daylight hours in small caves or hollow tree trunks in a nest of twigs, bark or fern fronds. It tended to retreat to the hills and forest for shelter during the day and hunted in the open heath at night.

A Comparative Study of Hearing in Owls of the Family Strigidae. Neth J. Zool; 23:131-167. Barn owls and boreal owl (Aegolius funereus) have (via convergent evolution) roughly similar ear structures, with the relative size of the ear structure and facial disc in owls generally indicative of the level of importance of acute hearing to their life history. Owls with relatively smaller ear slits and shallower or vestigial facial discs tend to skew towards more crepuscular or partially diurnal behaviors, whereas owls such as long-eared owls are more or less entirely nocturnal.

Proterosuchus had mesopic vision, indicating that it was adapted to see well in both bright and dim light. Mesopic vision is characteristic of cathemeral animals, which are active in both night and day, and crepuscular animals, which are active in twilight. Adaptations to see in dim light may have been ancestral to archosaurs, and Proterosuchus may have been an early example of this trend. However, Proterosuchus lived near the Antarctic Circle, so its mesopic vision may have instead been an adaptation to the highly seasonal day lengths it experienced.

Platypleura is a genus of cicadas that occurs widely across Africa and southern Asia. Some of the South African species are remarkable for their endothermic thermoregulation that enables crepuscular signalling, an adaptation that reduces risk of predation and enables a greater range for their calls. In field experiments their maximum body temperature while calling at dusk, was measured at 22 °C above ambient temperature. The Platypleurini are distributed from the Cape in South Africa, throughout sub-Saharan Africa and Madagascar, through India and south East Asia, to Japan.

These burrows are commonly made more secure by being dug among tree roots. They are good climbers of cliffs and trees.The Fur Bearing Mammals of the Soviet Union, produced by London's Hudson Bay, in association with v/o sojuzpushnina They are primarily crepuscular, hunting during the hours of twilight, but become more active in the day during the mating season. Their dens are well hidden, and lined by grass and shed fur, but may be temporary, especially during the winter, when the animal travels more widely in search of prey.

If You Wait received generally positive reviews from music critics. At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream publications, the album received an average score of 75, based on 19 reviews. Andy Gill of The Independent summarised the album's production and instrumentation as "all beautifully sketched to evoke the crepuscular intimacies of the songs." A large quantity of praise went to the vocal ability of Reid, whose husky contralto vocals have been described as "defining and soulful" by Clash magazine and "emotive" and "folky" by Drowned in Sound.

The Papuan swiftlet, Aerodramus papuensis, has three toes instead of the usual four in this group. It has the ability to echolocate, but whereas other previously studied species use echolocation primarily while flying in their caves, the Papuan swiftlet appears to be nocturnal or crepuscular and uses echolocation while active outside at night. It uses single, not double, clicks. DNA sequence data provides strong support for a basal relationship between A. papuensis and other Aerodramus taxa and suggest that this species and the waterfall swift Hydrochous gigas, are sister taxa, a relationship that would indicate paraphyly of the genus Aerodramus.

They are social, living in the wild in small groups that consist of several females (sows), a male (boar), and the young (which, in a break with the preceding porcine nomenclature, are called "pups" not "piglets"). They move together in groups (herds) eating grass or other vegetation, and do not store food. While they do not burrow themselves or build nests, they frequently seek shelter in the burrows of other animals, as well as in crevices and tunnels formed by vegetation. They tend to be most active during dawn and dusk (crepuscular), when it is harder for predators to spot them.

These fish are usually diurnal in the laboratory, but in the wild they can be diurnal, crepuscular, or nocturnal. The lake chub has large optic lobes in its brain and is therefore presumed to be a good sight feeder.Davis, B.J., and Miller, R.J., 1967, Brain patterns in minnows of the genus Hybopsis in relation to feeding habits and habitats, Copeia 1967: 1-39 It can, however, feed at night also.Emery, A.R., 1973, Preliminary comparisons of day and night habits of freshwater fish in Ontario lakes, Journal of the Fisheries Research Board of Canada 30: 761-774.

Thomas's yellow bat inhabits many habitats, such as both evergreen and deciduous forest, thorn shrub, open areas, and villages, though it appears to favor slightly disturbed deciduous forests. Like other species in its genus, the Thomas's yellow bat can take refuge in buildings and hollow trees, although its roosts are unknown. The species is crepuscular, with peaks of activity within an hour of both dusk and of dawn, flying low to the ground along wide trails or roads. The Thomas's yellow bat is an insectivore, feeding on small, flying insects and with established hunting routes among individuals.

Close jaguar encounter in the Belize Zoo ;Nocturnal Tour Apart from the traditional day time tour of the zoo, visitors are able to arrange night tours of the zoo, to see activity of the crepuscular and nocturnal animals. The animals on the tour include the tapirs, jaguars, margays, kinkajous, crocodiles, peccaries and howler monkeys. ;Junior Buddy encounter "Junior Buddy" is a young jaguar born and raised in the Belize Zoo. A result of the Problem Jaguar Rehab Program (his mother was a rescued problem jaguar), Junior has been trained to perform several tricks in return for snacks, a form of positive reinforcement training.

Two rivers, the Amu Darya and Sir Darya, flow from the mountains and crepuscular rays emanate from the rising sun at the rear of the emblem. The Khumo is perched on a banner at the base of the cotton and wheat borders which bears the national colors and the name of the country in Latin script (). Karakalpakstan, an autonomous republic within Uzbekistan uses an emblem based on Uzbekistan's, but featuring the regional colors blue, gold, and green. It features only one river, the Amu Darya, along with a local monument at the background of the emblem, adjacent to the mountains.

The comic ' by science-fiction writer Serge Lehman has been regarded by critics as the French reply to The League.L-atalante.com It uses proto-superhumans and supervillains from European pulp literature of the early twentieth century, but in a whole different perspective as Lehman is not mainly focused on English literature (as Moore does), mixes those real fictional characters equally with real prominent historical figures and builds a crepuscular alternate history story whose aim is to explain on a historical and psychoanalytical level why all European super-heroes disappeared from popular culture and European collective memory with World War II.

Owls, however, have also evolved to hunt at dusk and dawn, and even during the day on rare occasions, so the predator avoidance advantage may not apply to owls in particular. Another theory is that hamsters, which are extremely sensitive to temperature fluctuations, may be crepuscular to avoid the extreme temperatures of full daylight and night time temperatures.Stacey OBrien; field notes Golden hamsters in captivity run two to five miles per 24-hour period and can store up to one ton of food in a lifetime. They keep their food carefully separated from their urination and nesting areas.

These all share with barred owls a penchance for nocturnality and crepuscular habits (although many voles are more correctly considered cathemeral)Barred Owl, OwlingHabitat Suitability Index Models:Barred Owl, US Fish and Wildlife Service While during other seasons, the diet of barred owls can be fairly diverse, the winter diet may be almost wholly rodents (i.e. mammals comprising about 98.4% of the all known winter diets). This was the case in winter in Montana, where 97.6% of 1153 prey items were montane voles or meadow voles, with a possible slight mixture of other voles.Holt, D. W., & Bitter, C. (2007).

The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill. The positioning of the egret's eyes allows for binocular vision during feeding, and physiological studies suggest that the species may be capable of crepuscular or nocturnal activity. Adapted to foraging on land, they have lost the ability possessed by their wetland relatives to accurately correct for light refraction by water. This species gives a quiet, throaty rick-rack call at the breeding colony, but is otherwise largely silent.

A young gerbil sitting by the food bowl to eat A mother gerbil sitting with four young gerbils A gerbil is a small mammal of the subfamily Gerbillinae in the order Rodentia. Once known as desert rats, the gerbil subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats. Most are primarily active during the day, making them diurnal (but some species, including the common household pet, exhibit crepuscular behavior), and almost all are omnivorous. Gerbils are related to mice and rats; they all belong to the family Muridae.

Short-beaked echidnas are typically active in the daytime, though they are ill-equipped to deal with heat because they have no sweat glands and do not pant. Therefore, in warm weather, they change their patterns of activity, becoming crepuscular or nocturnal. Body temperatures above 34 °C (93 °F) are believed to be fatal, and in addition to avoiding heat, the animal adjusts its circulation to maintain a sustainable temperature by moving blood to and from the skin to increase or lower heat loss. In areas where water is present, they can also swim to keep their body temperatures low.

Other anglers are not as bothered by tubers, pointing out most tubing takes place during daylight hours rather than the crepuscular times at which trout are most active. The Shandaken Town Board proposed a law in 1983 that would have limited tubing to the lower stretch during prescribed hours, required bathroom facilities and levied a 10-cent surcharge on each rented tube to cover the expenses to the town. It was not adopted, but later the town required a special use permit under its zoning code. That requirement was dropped after one of the tube-rental businesses challenged it in court.

In some drainage systems the redeye barb undertakes seasonal migratory movements. The redeye barb is crepuscular and prefers subdued light but it is also active during the night. Its main prey is invertebrates. There were previously three recognised subspecies but one of these has now been recognised as a separate species Enteromius profundus and the other two are now considered to be morphs of a single monotypic but polymorphic species The redeye barb is a small barb which has salmon or orange-tinted fins, edged with black and a conspicuous red upper half to the eye.

232 The verdict was echoed and amended by those of other critics. Martin finds that it applies to many of Fondane's early poems, where "explosive" imagery is central, but opines that, generally toned down by melancholy, their message too blends into a new form of "crepuscular wisdom".Martin, p. XXVII–XXXI Scholar Dan Grigorescu stresses that the Neo-romantic and Symbolist element is dominant throughout the Priveliști volume and, contrary to Crohmălniceanu's thesis, argues that Fondane's projection of the self into the nature is not Expressionist, but rather a convention borrowed from Romanticism (except for "perhaps, [...] the exacerbated dilatation" in scenes in which terrified cattle are driven into town).

It is resident on the coasts and islands of the Indian Ocean, where it feeds on crabs and other small animals. They are gregarious and will feed in large groups, at night and during dawn and dusk as well as during the day; this crepuscular and nocturnal behaviour is more common during the breeding season. They breed around the Arabian Sea of Pakistan, Gulf of Oman and the Persian Gulf, Red Sea and Somalia in the months of April to July then disperse across the Indian Ocean in August as far as the Andaman Islands and Sri Lanka in the east and Tanzania and Madagascar.

Although predominantly using vision to locate their prey, adults may also make use of olfactory cues. No species are known to hunt at night, but some are crepuscular, perhaps taking advantage of newly hatched flies and other aquatic insects at a time when larger dragonflies are roosting. In tropical South America, helicopter damselflies (Pseudostigmatidae) feed on spiders, hovering near an orb web and plucking the spider, or its entangled prey, from the web. There are few pools and lakes in these habitats, and these damselflies breed in temporary water bodies in holes in trees, the rosettes of bromeliads and even the hollow stems of bamboos.

The activity patterns of the jaguar have been found to coincide with the activity of their main prey species in their biomes. Camera trap studies have shown that jaguars primarily have a crepuscular–nocturnal activity pattern in all the biomes that they are found in; however jaguars have been recorded to have considerable diurnal activity in thickly forested regions of the Amazon Rainforest and the Pantanal, as well as purely nocturnal activity in other regions such as the Atlantic forest. The jaguar is a stalk-and-ambush rather than a chase predator. The cat will walk slowly down forest paths, listening for and stalking prey before rushing or ambushing.

Initially described as "crepuscular" (active at dawn and dusk), anthropologist Ian Tattersall stimulated additional research and coined the new term "cathemeral", although many non- anthropologists prefer the terms "circadian" or "diel". In order to conserve energy and water in their highly seasonal environment, mouse lemurs and dwarf lemurs exhibit seasonal behavioral cycles of dormancy where the metabolic rate and body temperature are lowered. They are the only primates known to do so. They accumulate fat reserves in their hind legs and the base of their tail before the dry winter season, when food and water are scarce, and can exhibit daily and prolonged torpor during the dry season.

One of the visually evident features the renderer included is a penumbra in the shadowing (soft edges), by using shadow maps. In contrast, id Tech 4, which featured volume-based shadows, had very sharply defined shadows. Numerous other advanced graphical effects such as various materials for lighting, high dynamic range rendering- centric effects, bloom, crepuscular rays (volumetric lighting), radiosity, soft particles, pixel shader effects, alpha to coverage, post processing, Screen Space Reflection, dynamic water surfaces, procedural animation, cloth simulation, depth of field, and motion blur, are contained. Multi-threaded processing on the CPU is done for many of its tasks, including rendering, game logic, AI, physics, and sound processing.

Though it existed far earlier than Archaeopteryx, its skeletal structure is allegedly more bird-like. Protoavis has been reconstructed as a carnivorous bird that had teeth on the tip of its jaws and eyes located at the front of the skull, suggesting a nocturnal or crepuscular lifestyle. Reconstructions usually depict it with feathers, as Chatterjee originally interpreted structures on the arm to be quill knobs, the attachment point for flight feathers found in some modern birds and non-avian dinosaurs. However, re-evaluation of the fossil material by subsequent authors such as Lawrence Witmer have been inconclusive regarding whether or not these structures are actual quill knobs.

The Indian nightjar (Caprimulgus asiaticus) is a small nightjar which is a resident breeder in open lands across South Asia and Southeast Asia. Like most nightjars it is crepuscular and is best detected from its characteristic calls at dawn and dusk that have been likened to a stone skipping on a frozen lake - a series of clicks that become shorter and more rapid. They are sometimes spotted on roads when their eyes gleam red in the spotlight of a vehicle. There is considerable plumage variation across its range and can be hard to differentiate from other nightjars in the region especially in the field.

A crepuscular/nocturnal species most active after dark and before dawn, spotted nightjars are usually observed roosting, walking or running along the ground and are rarely seen perching in trees. They are often found on roads at night and have been observed hawking insects with highly maneuverable flight around campfires, artificial lighting and flowering bushes. When flushed, individuals may initially fly only a short distance before landing, but when facing more persistent threats may fly further away beyond sight. If threatened while brooding, the spotted nightjar may begin hissing, opening its bill widely and spreading its wings and tail in a defensive posture or distraction display.

A litter of beech marten kits in а farm outbuilding in the village of Orlintzi, Bulgaria Beech marten fighting a European otter, as illustrated in Brehm's Life of Animals The beech marten is mainly a crepuscular and nocturnal animal, though to a much lesser extent than the European polecat. It is especially active during moonlit nights. Being a more terrestrial animal than the pine marten, the beech marten is less arboreal in its habits, though it can be a skilled climber in heavily forested areas. It is a skilled swimmer, and may occasionally be active during daytime hours, particularly in the summer, when nights are short.

Amietia fuscigula is largely diurnal, though its call and breeding activity are mainly nocturnal or crepuscular. It prefers permanent water and commonly colonises dams and other artificial water bodies, but in some regions it is limited to seasonal transient water bodies. Where it occupies farm dams, it commonly emerges during the morning and takes up an inconspicuous position on the bank where it basks until the sun becomes too intense near noon. While basking, it is much sought by predators such as herons and is accordingly shy; one of its most familiar manifestations is a series of plops as frogs successively leap into the water while any threat walks by.

It is crepuscular and vocal at dawn and dusk with a series of staccato Twick-too...Twick-too... Twick-too or yak-wak.. yak-wak calls. The notes are repeated at the rate of about 1 per second and uttered 2 to 16 times and several birds in the vicinity may join in the calling. Jerdon described the Telugu name of the species as Adavi wuta-titti meaning "Jungle empty-purse". This name may however have been in error since Salim Ali and Hugh Whistler found villagers mystified by the name when they searched for the species near Borgampad and Nelipaka during the Hyderabad state survey of 1931.

A second peculiarity is the reduction of eyes in all cavernicolous species. This contrasts with most nocturnal or crepuscular species, in many of which there is a strong tendency to adapt to low light levels by responding to selection for large, highly sensitive eyes. A form of adaptation common to many cave insects as well as some external predatory species, is elongation of appendages, especially the antennae, palps and forelegs that assist in precise location of prey before striking. Many also bear elongated sensory organs, typically setae, as for example, in the beetle Scotoplanetes arenstorffianus, in which there are well developed setae, including on the elytra and also supraorbitally, but the eyes themselves are absent.

Many of the members of the subfamily Dipsadinae are typically nocturnal and some of the more commonly observed species present even in suburban areas on both islands are the false mapipire (Leptodeira annulata ashmeadi) and the slug-eating snake (Sibon nebulata). Other interesting Dipsadinae include the water mapipire (Helicops angulatus) a habitat specialist of freshwater and brackish water systems of lowland Trinidad, the mainly diurnal beh belle chemin (Erythrolamprus melanotus nesos) of forest and edge habitats on both islands and the rare crepuscular red snake (Erythrolamprus ocellatus) endemic to the forest and edge habitats of northeastern Tobago. There are no dangerous venomous snakes on Tobago. There are only four dangerous venomous snakes on Trinidad.

The Japanese and Malayan night herons resemble each other, being relatively short-billed and overall brown with a dark line from the throat to the upper belly. The larger white-eared and white-backed night herons are darker, with distinctive white markings on the face and neck in the former, and an entirely black head in the latter. Their behavior, especially that of the white-eared night heron, is relatively poorly known compared to that of other night herons, but they nest alone or in small groups, and a clutch of two to five eggs has been recorded. While generally nocturnal and crepuscular, they have been recorded feeding during the day in clouded weather.

Like all bears, brown bears can stand on their hindlegs and walk for a few steps in this position, usually motivated to do so by curiosity, hunger or alarm The brown bear is often described as nocturnal. However, it frequently seems to peak in activity in the morning and early evening hours. Studies have shown that activity throughout the range can occur at nearly any time of night or day, with bears who dwell in areas with more extensive human contact being more likely to be fully nocturnal. Furthermore, yearling and newly independent bears are more likely to be active diurnally and many adult bears in low-disturbance areas are largely crepuscular.

Knight Lore atmosphere, which Sinclair User described as a "crepuscular world of claustrophobic menace", inspired many curious questions on the part of the adventurer in contemporaneous 1985 reviews. Crash appreciated the imaginative mystery of the game as they attempted to answer why Sabreman turns into a werewolf, who they preferred to play as, and what the collectible objects throughout the castle do. Sabreman's werewolf transformation sequence, in particular, annoyed CVG and traumatised players, according to Well Played, a book of academic close readings of video games, as players empathised with the suffering Sabreman. The game design gave the impression that the castle was far grander in scale than it was in reality, and Crash wrote that the game's novel eight-way direction scheme suited the 3D space.

English Touring Opera's website In the same year came When Adam Fell, a BBC commission for orchestra based on the chromatic bass from the Bach chorale 'Durch Adam's Fall ist alles Verderbt', first introduced to Goehr by his teacher Olivier Messiaen. To These Dark Steps/The Fathers are Watching (2011–12), written for tenor, children's choir and ensemble, sets texts by Israeli poet Gabriel Levin concerning the bombing of Gaza during the Iraq war and was premiered in a concert marking Goehr's 80th birthday. Largo Siciliano (2012) is a trio praised for its mastery of aural balance between the unusual combination of violin, horn and piano, 'from opening crepuscular melancholy to an ending which just seems to vanish into oblivion.

Numerous passerine and songbirds such as the titmouse (Baeolophus bicolor), purple finch (Haemorhous purpureus), black-capped chickadee (Poecile atricapillus), jays/crows (family Corvidae), wren (family Troglodytidae), warbler (family Parulidae), dove (family Columbidae), woodpecker (family Picidae) and thrush (family Turdidae) have been spotted. Birds of prey encountered include owls, especially the barred owl (Strix varia), and hawks (mostly genus Buteo). Throughout the day, but most frequently during the crepuscular and predawn hours, the trill and tremolo of the common loon (Gavia immer) can be heard on the pond. Far less frequently encountered, but occasionally reported, are sights of black bear (Ursus americanus), North American porcupine (Erethizon dorsatum), white- tailed deer (Odocoileus virginianus), common raccoon (Procyon lotor), fisher (Pekania pennanti) and moose (Alces alces).

A visual representation of the twilight period from dawn to sunrise, when matutinal activity occurs The dimly lit twilight period between dawn and sunrise, when animals engage in matutinal activities Matutinal, matinal (in entomological writings), and matutine are terms used in the life sciences to indicate something of, relating to, or occurring in the early morning. The term may describe crepuscular animals that are significantly active during the predawn or early morning hours. During the morning twilight period and shortly thereafter, these animals partake in important tasks, such as scanning for mates, mating, and foraging. Matutinal behaviour is thought to be adaptive because there may be less competition between species, and sometimes even a higher prevalence of food during these hours.

Like other swallows, the white-eyed river martin feeds on insects, including beetles, which are caught on the wing. Given its size and unusual mouth structure, it may well take larger insects than other swallows. This species is described as graceful and buoyant in flight, and, like its African relative, appears reluctant to use perches, behaviour that, together with its unusual toe-shape and the fact that mud was found on the toes of one of the first specimens, suggest that this species may be relatively terrestrial. Pamela C. Rasmussen suggested that, given its unusually large eyes, the species might be nocturnal or at least crepuscular, a factor that could make it very inconspicuous, and thus partly explain how it remained undetected for so long.

Front view of the head of Lamia textor The head, having mouthparts projecting forward or sometimes downturned, is usually heavily sclerotized and is sometimes very large. The eyes are compound and may display remarkable adaptability, as in the case of the aquatic whirligig beetles (Gyrinidae), where they are split to allow a view both above and below the waterline. A few Longhorn beetles (Cerambycidae) and weevils as well as some fireflies (Rhagophthalmidae) have divided eyes, while many have eyes that are notched, and a few have ocelli, small, simple eyes usually farther back on the head (on the vertex); these are more common in larvae than in adults. The anatomical organization of the compound eyes may be modified and depends on whether a species is primarily crepuscular, or diurnally or nocturnally active.

By biomass and reproductive success within populations, these are certain to be the most significant food source to the species (at least in North America). Adult Sylvilagus rabbits known to be hunted by red-tails can range from the brush rabbit (Sylvilagus bachmani) to the Tres Marias rabbit (Sylvilagus graysoni) at while all leporids hunted may range the pygmy rabbit (Brachylagus idahoensis) to hares and jackrabbits potentially up twice the hawk’s own weight. While primarily crepuscular in peak activity, rabbits and hares often foraging both during day and night and so face almost constant predatory pressure from a diverse range of predators. Male red-tailed hawks or pairs which are talented rabbit hunters are likely have higher than average productivity due to the size and nutrition of the meal ensuring healthy, fast- growing offspring.

Examples of variables with bimodal distributions include the time between eruptions of certain geysers, the color of galaxies, the size of worker weaver ants, the age of incidence of Hodgkin's lymphoma, the speed of inactivation of the drug isoniazid in US adults, the absolute magnitude of novae, and the circadian activity patterns of those crepuscular animals that are active both in morning and evening twilight. In fishery science multimodal length distributions reflect the different year classes and can thus be used for age distribution- and growth estimates of the fish population.Introduction to tropical fish stock assessment Sediments are usually distributed in a bimodal fashion. Bimodal distributions are also seen in traffic analysis, where traffic peaks in during the AM rush hour and then again in the PM rush hour.

What all primary rodent prey species share is that they are either nocturnal or crepuscular and are often common to abundant in openings of woods and rocky environments. The reason Eurasian eagle-owls take rats, which associate rather closely with humans, much more regularly than they take house mice (Mus musculus) is not their larger size (many other rodents regularly taken by eagle-owls are as small or smaller than a house mouse) but the rat's ability to flourish along the edges of crop fields, refuse dumps, roadsides and abandoned buildings and fields, whereas the mice are more closely tied to active human habitations. A single refuse dump can host several thousand rats and eagle-owl territories that include dumps can locally expect higher productivity due to the abundance of this food source.Penteriani, V., Gallardo, M., & Roche, P. (2002).

In his biography of Pound, David A. Moody writes that the collection included an implicit challenge to the "crepuscular spirit" prevalent in contemporary literature, one which has drawn little attention yet can be found in certain poems and the collection's arrangement. He notes a progression in which persons who let their passion get the best of them are, implicitly, relegated to a Dantean Hell. In two of the poems ("Famam Librosque Cano" and "Scriptor Ignotus"), he writes, Pound appears to be questioning his own poetry, yet also showing unbound pride at his ability. This last poem, according to Moody, is the culmination of this progression and challenge: "If 'La Fraisne' represented the lowest state of being, then in 'Scriptor Ignotus' we have the poet himself as aspiring to the most exalted state of his poetic soul".

Cathemerality, sometimes called metaturnality, is the behaviour in which an organism has sporadic and irregular intervals of activity during the day or night in which food is acquired, socializing with other organisms occurs, and any other activities necessary for livelihood are performed. It has been defined as follows: "The activity of an organism may be regarded as cathemeral when it is distributed approximately evenly throughout the 24 h of the daily cycle, or when significant amounts of activity, particularly feeding and/or traveling, occur within both the light and dark portions of that cycle." Many animals do not fit the traditional definitions of being strictly nocturnal, diurnal, or crepuscular, often by factors that include the availability of food, predation pressure, and variable ambient temperature. As a result, many species, particularly among primates, may be classified as cathemeral.

Between E3 2009 and the time the game shipped, morphological anti-aliasing (MLAA) was added, which graphics engineer Ben Diamand said "improved edges dramatically and saved substantial amounts of frame-rate." Diamand also said that "depth-of-field, motion blur, crepuscular 'god' rays and refraction were either added or improved in quality and speed" during that same time period. On April 12, 2012, Sony released a teaser image for Ascension on its official PlayStation Facebook page, which was followed by the game's announcement on April 19 on PlayStation.Blog. Todd Papy, who had previously worked as a designer on God of War and God of War II and as design director on God of War III, assumed the role of game director; God of War III director Stig Asmussen was busy with another project at Santa Monica and did not work on Ascension.

Most owls share an innate ability to fly almost silently and also more slowly in comparison to other birds of prey. Most owls live a mainly nocturnal lifestyle and being able to fly without making any noise gives them a strong advantage over their prey that are listening for the slightest sound in the night. A silent, slow flight is not as necessary for diurnal and crepuscular owls given that prey can usually see an owl approaching. While the morphological and biological mechanisms of this silent flight are more or less unknown, the structure of the feather has been heavily studied and accredited to a large portion of why they have this ability. Owls’ feathers are generally larger than the average birds’ feathers, have fewer radiates, longer pennulum, and achieve smooth edges with different rachis structures.

Crepuscular rays are seen in St. Peter's Basilica at certain times each day. After the crucifixion of Jesus, it is recorded in the Biblical book of the Acts of the Apostles that one of his twelve disciples, Simon known as Saint Peter, a fisherman from Galilee, took a leadership position among Jesus' followers and was of great importance in the founding of the Christian Church. The name Peter is "Petrus" in Latin and "Petros" in Greek, deriving from "petra" which means "stone" or "rock" in Greek, and is the literal translation of the Aramaic "Kepa", the name given to Simon by Jesus. (John 1:42, and see Matthew 16:18) Catholic tradition holds that Peter, after a ministry of thirty-four years, travelled to Rome and met his martyrdom there along with Paul on 13 October 64 AD during the reign of the Roman Emperor Nero.

A rendering of volumetric lighting through a window Volumetric lighting, also known as “god rays”, is a technique used in 3D computer graphics to add lighting effects to a rendered scene. It allows the viewer to see beams of light shining through the environment; seeing sunbeams streaming through an open window is an example of volumetric lighting, also known as crepuscular rays. The term seems to have been introduced from cinematography and is now widely applied to 3D modelling and rendering especially in the field of 3D gaming. In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume": as a result, light has the capability to give the effect of passing through an actual three-dimensional medium (such as fog, dust, smoke, or steam) that is inside its volume, just like in the real world.

In this poem, and in another entitled 'Ocaso y aurora' (Sunset and Aurora), Guanes reveals to be a writer representative of his time..." In 1984, Editorial Alcándara published a Poetic Anthology with the best of his literary production. In the presentation of the book could be read: "Bordering between the late romanticism and the initial approaches to the Paraguayan poetic modernism, the scarce but refined work from Alejandro Guanes [...] drops a tenuous crepuscular illumination through a hole generation of national writers. From the penumbra of the pain, dressed of invincible memories, with the evidence of the immortal luck that darkly motivates the precarious palpitation of men, the poet named his time and his people, never forgetting a raised love to the fatherland, the scenario of unfortunate blood that occupied his youth". Carlos R. Centurión on his impressive "History of the Paraguayan literature" says that "Alejandro Guanes, in the first decade of the 20th Century, wrote "La cámara oscura" (The Dark Chamber", a dramatic comedy that never released".
