The white-billed crow (Corvus woodfordi) is a member of the crow family found on the Solomon Islands.
It is a short and stocky forest bird (40–41 cm in length) with a short, squared-off tail and a relatively large head with a very distinctive deep and curved pale ivory-coloured bill with a darker tip. The dark nasal bristles, though not thick, are quite apparent against the pale coloured bill. The bird overall is very glossy black with a greenish-purple gloss to the head and purple gloss to the rest of the body. The iris is pale grey or white in the adult bird and the legs and feet are black.
The voice is described as being reminiscent of the Torresian crow but higher in pitch and faster, giving an "ao-ao-ao" sound.
This species is confined to the central part of the Solomon Islands and can be found specifically on the islands of Choiseul, Isabel and Guadalcanal where it forages in small family groups through the trees, feeding on various insects and fruits. It is normally difficult to view as it often remains well hidden in the high forest canopy while feeding and even flying low, just over the tops of the trees when moving on.
As is the case with many forest crows, there is little information on the species' breeding habits.
The thick-billed raven, a corvid from the Horn of Africa, shares with the common raven the distinction of being the largest bird in the corvid family, and indeed the largest of the passerines. The thick-billed raven averages 64 cm (25 in) in length, with a range of 60 to 70 cm and weighs approximately 1.15 kg (2.5 lb) in females and 1.5 kg (3.3 lb) in males on average. Its size is about the same as the largest subspecies of common raven but some common raven subspecies are rather smaller and, going on average weights, the thick-billed raven is likely the heaviest extant passerine. The thick-billed raven is about 25% heavier on average than the Australasian superb lyrebird, which is sometimes erroneously titled the largest passerine.
The pied crow is a widely distributed African bird species in the crow genus.
The Cape crow or black crow is slightly larger than the carrion crow and is completely black with a slight gloss of purple in its feathers. It has proportionately longer legs, wings and tail too and has a much longer, slimmer bill that seems to be adapted for probing into the ground for invertebrates. The head feathers have a coppery-purple gloss and the throat feathers are quite long and fluffed out in some calls and displays.
The brown-necked raven is a larger bird than the carrion crow though not as large as the common raven. It has similar proportions to the common raven but the bill is not so large or deep and the wings tend to be a little more pointed in profile. The head and throat are a distinct brownish-black giving the bird its English name, while the rest of the plumage is black glossed with purple, blue or purplish-blue. Like the common raven, thick-billed raven and white-necked raven, it is one of the larger raven species. The feathers of this species often fade quite quickly to a brownish black and the bird can look distinctly brown by the time it moults. The feet, legs and bill are black. The dwarf raven was formerly considered a subspecies but this bird now appears to be closer to the pied crow than this species.
The large-billed crow, formerly referred to widely as the jungle crow, is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill, which is the source of its scientific name macrorhynchos and it is sometimes known by the common name thick-billed crow. It can also be mistaken for a common raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827. The eastern jungle crow and Indian jungle crow were once considered conspecific and together called the jungle crow.
The Cuban crow is one of four species of crow that occur on islands in the Caribbean. It is closely related to the white-necked crow and Jamaican crow, with which it shares similar features. The fourth Caribbean crow, the palm crow, is a later arrival in evolutionary terms, and shows characteristics more akin to North American species, such as the fish crow, which it is probably closely related to.
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.
The white-necked crow is the largest of the four Caribbean corvids. It is endemic to the island of Hispaniola ; it was formerly also extant on Puerto Rico, but has been extirpated there due to considerable forest clearance and hunting.
The gray crow, formerly known as the bare-faced crow, is about the same size as the Eurasian carrion crow but has somewhat different proportions and quite atypical feather pigmentation during the juvenile phase for a member of this genus.
A crow is a bird of the genus Corvus, or more broadly a synonym for all of Corvus. Crows are generally black in colour. The word "crow" is used as part of the common name of species including
The pale-vented pigeon is a large pigeon found in the tropical Americas. Formerly often placed in Columba, it actually belongs to a clade of the older New World genus Patagioenas. With its relatives it represents an evolutionary radiation extending through most of the warm-temperate to tropical Americas. Grey-hued birds, even their males generally lack iridescent display plumage, although the present species has some coppery gloss on the nape.
The yellow-faced myna is a species of starling in the family Sturnidae. It is found in New Guinea and nearby smaller islands, where its natural habitat is subtropical or tropical moist lowland forests. The long-tailed myna was formerly included as a subspecies. One of the largest species of starling, this species attains 23 to 26 cm in length and weighs around 217 g (7.7 oz). They have dark plumage with a metallic lustre and bright orange facial markings and beak. These birds are social and omnivorous. Their diet consists of fruit and insects for which they forage high in the canopy. They are common birds with a wide range, and the International Union for Conservation of Nature has assessed their conservation status as being of "least concern".
The Japanese wood pigeon is a species of columbid bird. It is found in East Asia along shorelines of the Pacific's Korea Strait, Philippine Sea and East China Sea. They are believed to be the largest representative of their genus, Columba, at 550 grams (1.2 lb) and 43 cm (17 in). Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. The species is in decline owing to habitat loss, habitat degradation, deforestation and hunting. This wood pigeon is endemic to the laurel forest habitat.
The pale mountain pigeon is a species of bird in the pigeon family Columbidae. It is endemic to the Solomon Islands archipelago, where it inhabits old-growth and secondary montane forest. It is a medium-size pigeon with an average length of 38 cm (15 in) and a weight of 310–385 g (10.9–13.6 oz). The head and neck are whitish-grey, the belly and lower breast are buffy-pink, and the vent and undertail coverts are pale grey. The upperparts are smoky-grey with darker fringes on the mantle and wing coverts. Both sexes look similar, but there can be large variation in individual appearance.
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 Bornean treepie is a passerine bird belonging to the treepies genus, Dendrocitta, of in the crow family, Corvidae. It is endemic to the island of Borneo. It is sometimes treated as a subspecies of the Sumatran treepie.
The Chihuahuan raven is a species of crow in the family Corvidae that is native to the United States and Mexico.
The Indian jungle crow is a species of crow found across the Indian Subcontinent south of the Himalayas. It is very common and readily distinguished from the house crow, which has a grey neck. In the past the species was treated as a subspecies of another crow species, but vocalizations and evidence from ectoparasite co-evolution and phylogenetic evidence have led to it being considered as a distinct species in modern taxonomic treatments. It differs in its voice from the large-billed crow found in the higher elevations of the Himalayas and the eastern jungle crow overlaps in the eastern part of its range. In appearance, it can be difficult to distinguish from either of these species although the plumage tends to be more uniformly glossed in purple and has a longer bill with a fine tip and a less arched culmen. The Himalayan species has a slightly wedge-shaped tail, unlike the rounded tail of the Indian jungle crow and tends to glide a lot.
