Glaucidium (owl)
Pygmy owls are members of the genus ''Glaucidium''. They belong to the typical owl family, Strigidae. The genus consists of 29 species distributed worldwide. These are mostly small owls, and some of the species are called "owlets". The genus includes nocturnal, diurnal, and crepuscular species. Birds in this genus mainly hunt large insects and other small prey. Taxonomy The genus ''Glaucidium'' was introduced in 1826 by the German zoologist Friedrich Boie. The type species was designated as the Eurasian pygmy owl by George Robert Gray in 1840. The genus name is from Ancient Greek ''glaukidion'' meaning "little owl" or "owlet". It is diminutive of ''glaux'' ''(γλαυξ)'' meaning "owl". A molecular phylogenetic study of the owls published in 2019 found that the widely distributed northern hawk-owl (''Surnia ulula'') is sister to the genus ''Glaucidium''. Species The genus contains 29 living species: * Eurasian pygmy owl (''Glaucidium passerinum'') * Pearl-spotted owlet ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cloud-forest Pygmy Owl
The cloud-forest pygmy owl or cloudforest pygmy owl (''Glaucidium nubicola'') is a short, muscular, small-sized species of owl found throughout the Andes of western Colombia and north-western Ecuador, being confined to cloud forests between 900–2000 m a.s.l.Freile, J.F.; Chaves, J.A.; Iturralde, G. & Guevara, E. (2003). Notes on the distribution, habitat and conservation of the cloud-forest pigmy-owl (''Glaucidium nubicola'') in Ecuador. ''Ornitología Neotropical,'' 14: 275–278. Below this altitudinal range the Central American pygmy owl (''Glaucidium griseiceps'') occurs; above it, the Andean pygmy owl (''Glaucidium jardinii'') occurs. Its epithet ''nubicola'' is Latin for "cloud-inhabiting", because this species is restricted to very humid cloud forests.Robbins, M.B. & Stiles, F.G. (1999).

Baja Pygmy Owl
The Baja pygmy owl (''Glaucidium hoskinsii'') or cape pygmy owl, is a subspecies of northern pygmy owl restricted to the Mexican state of Baja California Sur. Although some taxonomists, including the International Ornithologists' Union, consider it to be a distinct species, other authorities, including the American Ornithological Society, do not consider it separate, and consider it to be a subspecies of the northern pygmy owl. Classification The American Ornithological Society considers the Baja pygmy owl a subspecies of the northern pygmy owl, ''Glaucidium gnoma'' (as it does several other populations). It has also been classified as a subspecies of the least pygmy owl. However, it is given the status of a separate species here following the ''Handbook of the Birds of the World''. According to one authority, DNA evidence suggests that the two species are not closely related. Etymology The epithet ''hoskinsii'' commemorates Francis Hoskins, an assistant to Marston Abbott Fr ...

Mountain Pygmy Owl
The mountain pygmy owl or northern pygmy owl (''Glaucidium gnoma'') is a small species of owl from the family Strigidae. They reside throughout southern Arizona, New Mexico and Mexico. There is current taxonomic debate regarding its classification as an independent species or subspecies from that of the northern pygmy owl. Similar plumage colour and different vocal patterns are the primary characteristics fuelling this confusion. The mountain pygmy owl hunts for small mammals and insects during the day from its high perches in pine-forested mountains, at elevations of 1,500 to 3,500 m. Breeding occurs once the female has chosen the appropriate cavity to form her nest. The female mountain pygmy owl will lay eggs between May and June. Owlets will leave their nests 23–30 days, after hatching. Although the International Union for Conservation of Nature (IUCN), has ranked this species as least concern, the increase in deforestation could impact the future population. Taxonomy Th ...

Northern Pygmy Owl
The northern pygmy owl (''Glaucidium californicum'') is a small owl Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers a ... native to western North America. Taxonomy Some taxonomic authorities, including the International Ornithologists' Union, separate this species from the mountain pygmy owl, the Baja pygmy owl, and the Guatemalan pygmy owl, while others, such as the American Ornithological Society, do not recognize the split and consider this bird conspecific with the group, with the northern pygmy owl taking the English name for them all. Furthermore, if the group is considered conspecific, ''G. gnoma'' becomes the scientific name because it is older. Clear differences in the territorial calls by males are the basis for the proposed split, with birds in the high elevations of Ariz ...

Albertine Owlet
The Albertine owlet (''Glaucidium albertinum'') or Prigogine's owlet, is a small species of small owl in the family Strigidae, native to the Albertine Rift montane forests. Taxonomy Some authorities include the Albertine owlet as a subspecies of the African barred owlet, but others, including Birdlife, treat it as a separate species.

The head is heavily spotted with whitish flecks, the upper parts are maroon-brown and the mantle and back are not barred. The chin, throat and upper breasts are maroon with broad creamy bars, and the rest of the underparts are off-white with dark chestnut spots, mainly on the flanks. The tail is brown with large white spots. The eyes are pale yellow. The body length is .

Chestnut-backed Owlet
The chestnut-backed owlet (''Glaucidium castanotum'') (often misspelled ''Glaucidium castanonotum''), is an owl which is endemic to Sri Lanka. This species is a part of the larger grouping of owls known as typical owls, Strigidae, which contains most of the smaller owl species. This species was formerly considered to be a subspecies of the jungle owlet. Description The chestnut-backed owlet is small and stocky, measuring in length. It resembles the jungle owlet in shape, size and appearance but the upperparts, scapulars and wing coverts are mainly chestnut brown, with darker barring. The underparts are white with blackish shaft-streaks.HENRY, GM 1971. A guide to the birds of Ceylon. Second edition. Oxford University Press, London. p. 200 The facial disc is mainly brown and the eyes are yellow. There is a white neckband. Sexes are similar in appearance, with no sexual dimorphism.

Jungle Owlet
The jungle owlet (''Glaucidium radiatum'') or barred jungle owlet is native to the Indian Subcontinent. The species is often found singly, in pairs or small groups, and they are usually detected by their calls at dawn and dusk. There are two subspecies, with that found in the Western Ghats sometimes considered a full species. Description This small owlet has a rounded head and is finely barred all over. There is no clear facial disk and the wings are brownish and the tail is narrowly barred in white. There are two subspecies, the nominate form is found in the plains of India and Sri Lanka, while ''G. r. malabaricum'' of the Western Ghats is shorter tailed and shows more brown on the head. It has been suggested that the latter may warrant full species status. The plumage on the upper parts is dark black-brown barred with white. The wing coverts have white and rufous patches. The primaries and secondaries are dark brown and barred with pale chestnut. The lower side is whitish or p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
