The Bismarck crow (Corvus insularis) is a species of crow found in the Bismarck Archipelago. It was considered by many authorities to be a subspecies of the Torresian crow (C. orru), but is now treated as a distinct species. [2] [3]
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 135 species are included in this family. The genus Corvus containing 47 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines.
The hooded crow, also called the scald-crow or hoodie, is a Eurasian bird species in the genus Corvus. Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.
The Torresian crow, also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises. The base of the feathers on the head and neck are white. The Torresian crow is slightly larger with a more robust bill than the morphologically similar little crow.
The little crow is an Australian species of crow, very similar to the Torresian crow in having white bases to the neck and head feathers but slightly smaller and with a slightly smaller bill. It has the same white iris that distinguish the Australian species from all other Corvus except a few island species to the north of Australia, and one from Eurasia, the jackdaw. Like the Australian raven, this species has a blue ring around the pupil.
The little raven is a species of the family Corvidae that is native to southeastern Australia. An adult individual is about 48–50 cm (19–19.5 in) in length, with completely black plumage, beak, and legs; as with all Australian species of Corvus, the black feathers have a grey base, and the iris of the adult bird is white . Although the little raven was first named by Gregory Mathews in 1912, it was only in 1967 that there was consensus to separate it from the Australian raven as a distinct species.
The house crow, also known as the Indian, greynecked, Ceylon or Colombo crow, is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping. It is between the jackdaw and the carrion crow in size but is slimmer than either. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in colour. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of colour in areas of the plumage.
The fish crow is a species of crow associated with wetland habitats in the eastern and southeastern United States.
The Jamaican crow is a comparatively small corvid. It shares several key morphological features with two other West Indian species, the Cuban crow and the white-necked crow of Hispaniola, which are very closely related to it.
A crow is a bird of the genus Corvus, or more broadly a synonym for all of Corvus. The word "crow" is used as part of the common name of many species. The related term "raven" is not linked scientifically to any certain trait, but is rather a general grouping for larger species of Corvus.
The Banggai crow is a member of the crow family from Banggai regency in the province of Central Sulawesi in Indonesia. It is listed as critically endangered by IUCN. It was feared extinct, but was finally rediscovered during surveys on Peleng Island off the southeast coast of Sulawesi by Indonesian ornithologist Mochamad Indrawan in 2007 and 2008.
The long-billed crow is a crow that is endemic to the Northern Maluku Islands. This crow is large with glossy plumage, a large bill and white irises. It is classified by the International Union for Conservation of Nature as a "near-threatened species".
The south Melanesian cuckooshrike is an uncommon species of bird in the cuckooshrike family. It is found in New Caledonia, Bougainville Island, the Solomon Islands, and Vanuatu. The species is a large (32–37 cm) cuckoo-shrike with a long square tail and all over dark grey plumage. The eye of adults is yellow, whereas that of the juvenile is dark. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The slender-billed crow is a Passerine bird of the family Corvidae, in the genus Corvus. The violet crow has been found to be distinct genetically and separated as Corvus violaceus. The small crow has been split as Corvus samarensis and the Palawan crow has also been split as Corvus pusillus.
The Flores crow is a species of bird in the family Corvidae. It is endemic to Indonesia.
The brown-headed crow is a passerine bird of the genus Corvus in the family Corvidae. Endemic to Indonesia, it has a fragmented distribution in subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest. It is threatened by habitat destruction and the IUCN has rated it as being "near-threatened".
The Bougainville crow is a species of bird in the crow family, Corvidae.
The violet crow is a species of the crow family, Corvidae, native to Seram, an island in Indonesia. It was long considered a subspecies of the slender-billed crow but has been shown to be divergent genetically. Violet crows have a dark black head and slightly blue black body and have a slightly shorter bill than most other crow species.
The small crow is a passerine bird in the genus Corvus of the family Corvidae. It was previously considered a subspecies of the slender-billed crow, but phylogenetic evidence indicates that both are distinct species, and it has thus been split by the International Ornithologists' Union.
The Palawan crow is a Passerine bird of the family Corvidae, in the genus Corvus. It was previously considered a subspecies of the slender-billed crow, but phylogenetic evidence indicates that both are distinct species, and it has thus been split by the International Ornithologists' Union.
