The Cuban crow (Corvus nasicus) is a crow species native to the northern Caribbean.
Two other Caribbean crow species, the white-necked crow (C. leucognaphalus) of Hispaniola and the Jamaican crow (C. jamaicensis), appear to be very closely related to it, sharing several key morphological features. The ancestor of the fourth and fifth species from this region, the Hispaniolan (C. palmarum) and Cuban palm crows (C. minutus), would appear to be a later arrival (at least in evolutionary terms); both species show more similarities to the fish crow (C. ossifragus) of mainland North America and two Mexican species. This is despite C. minutusbeing sympatric with C. nasicus on Cuba, indicating two distinct arrivals of crows onto the island, and a resulting niche differentiation , similar to C. leucognaphalusand C. palmarumon Hispaniola.
A stocky, medium-sized (40–42 centimetres or 16–17 inches in length) forest crow, the bill of this species is long and deep with a gentle curve towards the tip giving a large headed profile. The nasal bristles sweep forward then upward and frequently reveal the nostrils which are hidden in almost all other members of the genus Corvus . There is a patch of dark grey bare skin behind the browinsh-red eye and at the base of the lower mandible. The black plumage has a bluish-purple gloss in good light. The bill, legs and feet are black.
It can be found quite commonly over most of the island of Cuba and on the nearby Isla de la Juventud, as well as the Turks and Caicos Islands, in woodland and areas that have been cleared for agriculture. It is frequently found around farms and villages where it seems to have adapted quite well to living in relatively close contact with human settlements.
Food consists of fruit and insects though it does appear to take human food readily and will scavenge for scraps where the opportunity arises. Large noisy flocks can be seen feeding in trees and it will also readily feed on the ground especially where grain and other seeds have been spilt or left unprotected on the surface of a field.
The voice is quite remarkable and is rather un-crow like, with strange liquid bubbling notes and high ringing sounds produced in various combinations. It also produces a thin screeched "aaaaauh" that rises in inflection.
The nest is built in tall trees, though little further information about breeding is recorded as yet.
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 carrion crow is a passerine bird of the family Corvidae and the genus Corvus which is native to western Europe and the eastern Palearctic.
The Australian raven is a passerine corvid bird native to Australia. Measuring 46–53 centimetres (18–21 in) in length, it has an all-black plumage, beak and mouth, as well as strong, greyish-black legs and feet. The upperparts of its body are glossy, with a purple-blue, greenish sheen; its black feathers have grey bases. The Australian raven is distinguished from the Australian crow, and other related corvids, by its long chest feathers, or throat hackles, which are prominent in mature birds. Older individuals and subadults have white irises, while the younger birds' eyes display blue inner rims; hatchlings and young birds have brown, dark irises until about fifteen months of age, at which point their irises become hazel-coloured, with an inner blue rim around each pupil, this lasting until they are roughly 2.5 to 3 years of age. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its species name coronoides highlighting its similarity with the carrion crow. Two subspecies are recognised, which differ slightly in their vocalisations, and are quite divergent, genetically.
The pied crow is a widely distributed African bird species in the crow genus of the family Corvidae.
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 American crow is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. American crows are the New World counterpart to the carrion crow and the hooded crow of Eurasia; they all occupy the same ecological niche. Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls and visual appearance are different.
The fish crow is a species of crow associated with wetland habitats in the eastern and southeastern United States.
The Tamaulipas crow is a crow found in northeastern Mexico and southern Texas.
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 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 and Saint Croix in the United States Virgin Islands, but has been extirpated from both islands due to considerable forest clearance and hunting for meat.
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.
The white-billed crow is a member of the crow family found on the Solomon Islands.
Pico Duarte is the highest peak in the Dominican Republic, on the island of Hispaniola and in all the Caribbean. At 3,101 m (10,174 ft) above sea level, it gives Hispaniola the 16th-highest maximum elevation of any island in the world. Additionally, it is only 85 kilometres northeast of the region's lowest point, Lake Enriquillo, 46 m below sea level. It is part of the Cordillera Central range, which extends from the plains between San Cristóbal and Baní to the northwestern peninsula of Haiti, where it is known as the Massif du Nord. The highest elevations of the Cordillera Central are found in the Pico Duarte and Valle Nuevo massifs.
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-sized species of Corvus.
The Hispaniolan palm crow is a relatively small corvid is endemic to the Caribbean island of Hispaniola where it was formerly very frequent, but is now reduced in population.
The Puerto Rican crow is an extinct crow species in the family Corvidae that was endemic to Puerto Rico and the United States Virgin Islands. Little is known about its habitat, but it possibly died out after the colonization of humans on these islands.
The Cuban palm crow is a relatively small corvid that is endemic to the Caribbean island of Cuba.
