Common Barn Owl
The western barn owl (''Tyto alba'') is a species of barn owl ''Tyto'' native to Europe, southwestern Asia, and Africa. It was formerly considered a subspecies group together with barn owls native to other parts of the world, but this classification was found to be paraphyletic with respect to some other members of the genus. The plumage on the head and back is a mottled shade of grey or brown; that on the underparts varies from white to brown and is sometimes speckled with dark markings. The facial disc is characteristically large and heart-shaped, with white plumage in most subspecies. This owl does not hoot, but utters an eerie, drawn-out screech. The western barn owl is nocturnal over most of its range, but in Great Britain, it also hunts by day. Barn owls specialise in hunting animals on the ground, and nearly all of their food consists of small mammals, which they locate by sound, their hearing being very acute. The owls usually mate for life unless one of the pair is kill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ashy-faced Owl
The ashy-faced owl (''Tyto glaucops'') is a species of bird in the barn-owl family Tytonidae. It is found on the Caribbean island of Hispaniola, on Dominica, and on several other islands of the Lesser Antilles. Taxonomy and systematics The ashy-faced owl was formally described in 1852 by the German naturalist Johann Jakob Kaup and given the binomial name ''Strix glaucops''. The specific epithet is from Ancient Greek ''glaukos'' meaning "blue-grey" or "glaucous". Kaup specified the type locality as Jamaica. This was an error and has been corrected to Hispaniola. The ashy-faced owl is now placed in the genus ''Tyto'' that was introduced in 1828 by Gustaf Johan Billberg. The taxonomy of the ashy-faced owl is unsettled. At one time it was considered conspecific with the barn owl ''sensu lato'' (''Tyto alba'').Bruce, M.D., G. M. Kirwan, and J. S. Marks (2020). Ashy-faced Owl (''Tyto glaucops''), version 1.0.

Rectrices
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the Bird wing, wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices ( or ), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift (force), lift, thereby enabling bird flight, flight. The flight feathers of some birds perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on ...

True Owl
The true owls or typical owls (family (biology), family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls and bay owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genus, genera. The Strigidae owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J. S.; Cannings, R.J. and Mikkola, H. (1999). "Family Strigidae (Typical Owls)". ''In'' del Hoyo, J.; Elliot, A. & Sargatal, J. (eds.) (1999). ''Handbook of the Birds of the World.

Barn Owl West Acre 1
A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain.Allen G. Noble, ''Traditional Buildings: A Global Survey of Structural Forms and Cultural Functions'' (New York: Tauris, 2007), 30. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings (or housebarns in US literature). In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing. Etymology The word ''barn'' comes f ...

Megascops
Screech owls are typical owls (Strigidae) belonging to the genus ''Megascops'' with 22 living species. For most of the 20th century, this genus was merged with the Old World scops owls in ''Otus'', but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphology (biology), morphological, and DNA sequence data. Screech owls are restricted to the Americas. Some species formerly placed with them are now considered more distinct (see #The splitting of Otus sensu lato, below for details). Description Similar to other owls, the screech owl females are larger than the males of their species. They have a compact size and shape. They are small and agile, and about 7 to 10 inches tall and have a wingspan around 18 to 24 inches. They have prominent, wide-set feather tufts with bright yellow/green eyes. They have different brownish hues with whitish, patterned underside. This coloration helps them get camouflage against the tree bark. Ecology ...

Golden Masked Owl
The golden masked owl (''Tyto aurantia'') is a barn owl endemic to the island of New Britain, Papua New Guinea. It is also known as New Britain barn owl, New Britain masked owl, Bismarck owl and Bismarck masked owl. As with other tropical barn owls, it is difficult to spot in the wild and therefore poorly studied. It is likely to be a lowland forest or coniferous species. Given the paucity of reliable information, it was for some time classified as a data deficient species by the IUCN. When its status could finally be evaluated properly, earlier assessments were found to be correct, and it is once again listed as a Vulnerable species in the 2008 red list.BLI (2008) General description Golden masked owls are characterized by their brown, light-brown, and white feathered plumages along with their arguably most distinctive feature - their heart-shaped, bright white face. There is considerable variation in the exact weight of the species, but most birds range from 0.9 to 1.7 pounds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Vocalization
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply ''birdsong'') are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the " winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andaman Masked Owl
The Andaman masked owl (''Tyto deroepstorffi'') is a barn owl endemic to the southern Andaman Islands archipelago of India, in the Bay of Bengal, Indian Ocean.Bruce, M.D., Christie, D.A., Kirwan, G.M. & Marks, J.S. (2017). Common Barn-owl (''Tyto alba''). In: del Hoyo, J., Elliott, A., Sargatal, J., Christie, D.A. & de Juana, E. (eds.). Handbook of the Birds of the World Alive. Lynx Edicions, Barcelona. (retrieved from http://www.hbw.com/node/54929 on 6 September 2017). Regarded by some authors as a subspecies of the common barn owl ('' Tyto alba''), it is recognized by others as a species in its own right. Taxonomy The species was named by Allan Octavian Hume after the collector Frederik Adolph de Roepstorff who shot it at Aberdeen, Andamans. Hume placed it in the genus ''Strix''. Some authors consider this bird to be a subspecies of the barn owl/western barn owl ''(Tyto alba)'', or the eastern barn owl (''Tyto javanica''), but König, in his ''Owls of the World'', recognized it ...
