Collared Sparrowhawk
The collared sparrowhawk (''Accipiter cirrocephalus'') is a small, slim bird of prey in the family Accipitridae found in Australia, New Guinea and nearby smaller islands. As its name implies the collared sparrowhawk is a specialist in hunting small birds. It is characterised by its slight brow ridges and slender feet. The last segment of their middle toe projects beyond the claws of the other toes. Description The collared sparrowhawk is 29–38 cm (tail about half ), with a wingspan 55–78 cm, the average male weighs 126 g, female 218 g. They are small, fierce, finely built with rounded wings, long square tail, yellow eyes and long legs. Adults have slate-grey upper parts, sometimes with a brown wash, and a chestnut half collar. The underparts are finely barred rufous and white. The under wing and tail are finely barred. The cere is cream to olive-yellow, the eyes yellow and the legs and feet yellow. The sexes are similar in appearance but males are smaller than fema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Accipitridae
The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents (except Antarctica) and a number of oceanic island groups. Some species are migratory. The family contains 255 species which are divided into 70 genera. Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family (Pandionidae), as is the secretary bird (Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data indicate the accipitrids analysed are indeed a distinct monophyletic group. Systematics and phylogeny ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crested Pigeon
The crested pigeon (''Ocyphaps lophotes'') is a bird found widely throughout mainland Australia except for the far northern tropical areas. Only two Australian pigeon species possess an erect crest, the crested pigeon and the spinifex pigeon. The crested pigeon is the larger of the two species. The crested pigeon is sometimes referred to as a topknot pigeon, a common name shared with the reddish crested '' Lopholaimus antarcticus'' of Eastern Australia. Taxonomy The species was described in 1822 by Temminck; it is the only species in the genus ''Ocyphaps'', established by G.R. Gray in 1842. Two subspecies are recognized: ''O. l. lophotes'', the nominate subspecies, occurring across the south of the continent; and ''O. l. whitlocki'', occurring in regions of the centre and north of Western Australia. The taxon was named for F. Lawson Whitlock, who made important collections of bird specimens in those areas. The species has also been placed as '' Geophaps'', perhaps allied wit ...

Spotted Bowerbird
The spotted bowerbird (''Chlamydera maculata'') is a sedentary, mid-sized passerine found across broad parts of the drier habitats of eastern Australia. The species is known for its remarkable behaviours, like many other bowerbirds (Ptilonorynchidae), which include bower building and decorating, courtship displays and vocal mimicry. Spotted bowerbirds are locally common, however, overall the population is thought to be in decline. Description At 29 cm in length, spotted bowerbirds are intermediate in size among the bowerbirds, but are rather slim and compact. Spotted bowerbirds are sexually monomorphic, with a pale rufous head that is streaked with grey-brown and a nape adorned with a lilac-pink crest. The upperparts are blackish-brown and marked extensively with amber spots, while the paler underparts are cream with greyish scalloping and barring and a slightly yellow shade to the lower belly and undertail. The bill is black, the eyes dark brown and the legs olive-brown. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pied Currawong
The pied currawong (''Strepera graculina'') is a black passerine bird native to eastern Australia and Lord Howe Island. One of three currawong species in the genus ''Strepera'', it is closely related to the butcherbirds and Australian magpie of the family Artamidae. Six subspecies are recognised. It is a robust crowlike bird averaging around in length, black or sooty grey-black in plumage with white undertail and wing patches, yellow irises, and a heavy bill. The male and female are similar in appearance. Known for its melodious calls, the species' name ''currawong'' is believed to be of indigenous origin. Within its range, the pied currawong is generally sedentary, although populations at higher altitudes relocate to lower areas during the cooler months. It is omnivorous, with a diet that includes a wide variety of berries and seeds, invertebrates, bird eggs, juvenile birds and young marsupials. It is a predator which has adapted well to urbanization and can be found in parks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accipiter
''Accipiter'' is a genus of Bird of prey, birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species (excepting the northern goshawk) are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a coracoid, procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus ''Hieraspiza''.Olson (2006) Extant accipiters range in size from the little sparrowhawk (''A. minullus''), in which the smallest males measure long, span across the wings and weigh , to the northern goshawk (''A. gentilis''), in which the largest females measure long, span across the wings, and weigh . These birds are slender with short, broad, rounded wings and a long tail which helps them mane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
