Asio
''Asio'' is a genus of typical owls, or true owls, in the family Strigidae. This group has representatives over most of the planet, and the short-eared owl is one of the most widespread of all bird species, breeding in Europe, Asia, North and South America, the Caribbean, Hawaii and the Galápagos Islands. Its geographic range extends to all continents except Antarctica and Australia. These are medium-sized owls, in length with wingspans. They are long-winged and have the characteristic facial disc. The two northern species are partially migratory, moving south in winter from the northern parts of their range, or wandering nomadically in poor vole years in search of better food supplies. 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 (''A ...

Short-eared Owl
The short-eared owl (''Asio flammeus'') is a widespread grassland species in the family Strigidae. Owls belonging to genus ''Asio'' are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. The short-eared owl will display its tufts when in a defensive pose, although its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands. Taxonomy The short-eared owl was formally described in 1763 by the Lutheran bishop Erik Pontoppidan under the binomial name ''Strix flammea''. The specific epithet is from the Latin ''flammeus'' meaning "flammulated" or "flame-coloured". This owl is now placed with seven other species in the genus ''Asio'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. Eleven subspecies are recognised: * ''A. f. flammeus'' – ( Pontoppidan, 1763): the nominate subspecies, found in North America, Europe, North Africa and n ...

Abyssinian Owl
The Abyssinian owl or African long-eared owl (''Asio abyssinicus'') is a medium-sized true owl.Burton, John A. 1984. "Owls of the world: their evolution, structure and ecology (Rev. Ed.)". Tanager Books Description The Abyssinian owl has dark brown eyes, a black bill and gray eyebrows. It is similar in appearance to the long-eared owl, ''Asio otus'', but their ranges do not overlap, and the Abyssinian owl is darker. It has prominent dark brown, white-edged ear-tufts that are slightly centrally located on the head.del Hoyo, J.; Elliott, A.; Sargatal, J. 1999. Handbook of the Birds of the World, vol. 5: Barn-owls to Hummingbirds. Lynx Edicions, Barcelona, Spain Behavior and reproduction ''Asio abyssinicus'' is a nocturnal owl. It uses the nests of other birds to raise its offspring. The claws of the Abyssinian owl are significantly stronger than other members of the genus; as a result a wider range of prey is available, including smaller birds, field mice, and shrews.

Madagascar Owl
The Madagascar owl (''Asio madagascariensis''), also known as the Madagascan owl or Madagascar long-eared owl, is a medium-sized owl endemic to the island of Madagascar. It is sometimes considered to be conspecific with the long-eared owl (''Asio otus''). Description The Madagascar owl is similar in appearance to the Holarctic long-eared owl in that it sits tall and at rest shows prominent ear tufts. The plumage is mainly brown with darker streaks and bars. It has distinctive bright orange eyes. The adults are brown above, and mottled with buff, especially across the mantle. The face is plain dark buff, with darker brown feathers around the eyes, on the edge of the facial disc, and on the ear tufts. The underparts are light brown with darker brown streaks which fade away towards the vent. The juvenile is covered in white down contrasting with a black facial disk and dark brown wings. It ranges from in length, making it the largest of the country's owls; females are larger than m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Striped Owl
The striped owl (''Asio clamator'') is a medium-sized owl with large ear tufts and a brownish-white facial disk rimmed with black. Its beak is black, and it has cinnamon-colored eyes. It has shorter, rounder wings than most of its close relatives. The upperparts are cinnamon with fine black vermiculation and heavy stripes. The underparts are pale tawny with dusky streaks. It is native to South America and parts of Central America. Taxonomy The striped owl was formally described by the French ornithologist Louis Jean Pierre Vieillot in 1808 under the binomial name ''Bubo clamator''. The specific epithet ''clamator'' is Latin meaning "shouter". The type locality is Cayenne in French Guiana. The striped owl was at one time placed in its own genus ''Rhinoptynx'' and was then transferred to the genus '' Pseudoscops''. A molecular study that compared mitochondrial DNA sequences indicated that it should be placed in the genus ''Asio''. This result was confirmed by a large molecular p ...

Jamaican Owl
The Jamaican owl (''Asio grammicus'') is a medium-sized owl that is endemic to the island of Jamaica. Taxonomy and systematics The Jamaican owl was previously considered the only member of the genus ''Pseudoscops'', but phylogenetic analysis has reclassified it within ''Asio''. It is monotypic. Description The Jamaican owl is long; one specimen of unstated sex weighed . This medium-sized owl has long ear tufts, dark brown eyes, and a rufous facial disk rimmed in black-flecked white. The adult's upperparts are rufous with fine dark brown vermiculation. The tail is also rufous, with dark brown bars. The breast and belly are rufous with narrow dark brown streaks. The juvenile's back is light grayish brown and the rest of its plumage is light cinnamon-buff.Olsen, P.D. and J. S. Marks (2021). Jamaican Owl (''Asio grammicus''), version 1.1.

Fearful Owl
The fearful owl (''Asio solomonensis'') is a medium-sized owl endemic to the Solomon Islands archipelago. It is generally seen at elevations of up to 800 m above sea level, where it is found in tall lowland or hill forests. Description The fearful owl is a large forest owl growing to a length of about . It has a rufous facial disk and distinct white eyebrows. The inner edge of the facial disk is also white. It is usually mottled brown with deep ochre underparts and blackish streaks. This species may be confused with the Solomon hawk owl, although the latter is slightly smaller and more slender. It is also similar in appearance to the laughing owl, which is now extinct. Its call is similar to a clear human scream, increasing in volume and tone and emitted in a series, each pulse being repeated at intervals of ten seconds. Distribution and habitat The fearful owl is endemic to the island of Bougainville in Papua New Guinea and to Choiseul Island and to Santa Isabel Island in th ...

Typical Owls
The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical 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. Volume 5: Barn-Owls to Hummingbirds.'' Lynx Edicions. They tend to have large heads, short tails, cryptic plumage, and round facial discs around the eyes.
