Frogmouths
The frogmouths are a group of nocturnal birds related to owlet-nightjars, swifts, and hummingbirds. Species in the group are distributed in the Indomalayan and Australasian realms. Biology They are named for their large flattened hooked bill and huge frog-like gape, which they use to capture insects. The three ''Podargus'' species are large frogmouths restricted to Australia and New Guinea, that have massive flat broad bills. They are known to take larger prey such as small vertebrates (frogs, mice, etc.), which are sometimes beaten against a stone before swallowing. The ten ''Batrachostomus'' frogmouths are found in tropical Asia. They have smaller, more rounded bills and are predominantly insectivorous. Both ''Podargus'' and ''Batrachostomus'' have bristles around the base of the bill, and ''Batrachostomus'' has other, longer bristles which may exist to protect the eyes from insect prey. In April 2007, a new species of frogmouth was described from the Solomon Islands and place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tawny Frogmouth
The tawny frogmouth (''Podargus strigoides'') is a species of frogmouth native to the Australian mainland and Tasmania and found throughout. It is a big-headed, stocky bird, often mistaken for an owl, due to its nocturnal habits and similar colouring, and sometimes, at least archaically, referred to as ''mopoke'' or ''mopawk'', a name also used for the Australian boobook, the call of which is often confused with that of the tawny frogmouth. Names Its name in reconstructed Proto-Pama–Nyungan is ''*tawa'' or ''*tawu''.Alpher, Barry. 2004. Pama-Nyungan: Phonological Reconstruction and Status as a Phylo-Genetic Group. In Claire Bowern and Harold Koch (eds.), ''Australian Languages: Classification and the Comparative Method'', 93–126, 387–574. Amsterdam: John Benjamins. Taxonomy The tawny frogmouth was first described in 1801 by the English naturalist John Latham. Its specific epithet is derived from Latin ''strix'' 'owl' and ''oides'' 'form'.

Gould's Frogmouth
Gould's frogmouth (''Batrachostomus stellatus'') is a nocturnal species of bird in the order Caprimulgiformes and the family Podargidae. It is one of the 12 species in the Batrachostomus genus. Its common name commemorates the English ornithologist and bird artist John Gould (1804-1881). Description Gould's frogmouth is a medium-sized bird that will approximately weight 47 to 48.5 g and measure 21 to 25 cm. It can be seen in two different morphs. They both have the same patterns except that one is light and the other one is dark. They are mostly brown and have a white collar with some scattered white spots on the cover of the wings. The underparts have oval-shaped spots that appears whitish. Contrarily to the other frogmouths, the males and females are very similar. However, some differences arise which permit their identification. The females will have a darker reddish-brown color. Moreover, females have brown iris and yellowish legs while the males have yellow iris and pinki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomons Frogmouth
The Solomons frogmouth (''Rigidipenna inexpectata''), also known as the Cinnamon frogmouth or Solomon Islands frogmouth, is a bird in the frogmouth family.

Javan Frogmouth
The Javan frogmouth (''Batrachostomus javensis''), sometimes known as Horsfield's frogmouth, is a species of bird in the family Podargidae. It is sometimes considered conspecific with the Blyth's and Palawan frogmouths. Found in Southeast Asia, Indonesia and the Philippines, it lives in subtropical or tropical moist lowland forest. Taxonomy The Javan frogmouth was first described in 1821 by the American naturalist Thomas Horsfield as ''Batrachostomus javensis''. The species was later split by Sibley and Monroe into ''B. javensis'' and ''B. affinis'' in 1990 and 1993, and in 1997, ''B. pygmaeus'', was described by Alviola as being a species "new to science". However, Holyoak in 1999 and Dickinson in 2003, synonymized these new species with ''B. javensis''. Description The species grows to a length of about . The upper parts are a mixture of brown, grey, buff and white, spotted with black. The scapulars have several large oval white spots. There is a white stripe above the eye a ...

Hodgson's Frogmouth
Hodgson's frogmouth (''Batrachostomus hodgsoni'') is a species of bird in the family Podargidae. It is found in Bangladesh, Bhutan, China, India, Laos, Myanmar, Thailand, and Vietnam. Its natural habitat is temperate forests. The common name commemorates the British naturalist Brian Houghton Hodgson. This bird is part of the same order as nightjars are. Both birds are nocturnal and they share similar rictal bristles on the bill which they use to know when to close their bill shut on insects as they hawk. This feature is just a hypothesis by scientists who do not completely understand the true use of those bristles yet. the frogmouth differs from its cousin by heavier bills, shorter and more rounded wings and upright posture when perched. Description Hodgson's frogmouth is one of the smaller members of the family Podargidae. As an adult, its length ranges between and it weighs approximately . The brown and gray plumage of this tropical bird resembles tree bark. This plumag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owlet-nightjar
Owlet-nightjars are small crepuscular birds related to the nightjars and frogmouths. Most are native to New Guinea, but some species extend to Australia, the Moluccas, and New Caledonia. A flightless species from New Zealand is extinct. There is a single monotypic family Aegothelidae with the genus ''Aegotheles''. Owlet-nightjars are insectivores which hunt mostly in the air but sometimes on the ground; their soft plumage is a cryptic mixture of browns and paler shades, they have fairly small, weak feet (but larger and stronger than those of a frogmouth or a nightjar), a tiny bill that opens extraordinarily wide, surrounded by prominent whiskers. The wings are short, with 10 primaries and about 11 secondaries; the tail long and rounded. Systematics A comprehensive 2003 study analyzing mtDNA sequences Cytochrome b and ATPase subunit 8 suggests that 11 living species of owlet-nightjar should be recognized, as well as another that became extinct early in the second millennium AD ...

Sunda Frogmouth
The Sunda frogmouth (''Batrachostomus cornutus'') is a species of bird, typically placed in the family Podargidae of the order Caprimulgiformes. Recent research suggests, however, that the old order Podargiformes should be re-established, wherein the Asian frogmouths would be placed in their own family, Batrachostomidae. It is found in Brunei, Indonesia, and Malaysia, where it occurs on Borneo and Sumatra. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucia ....
