- Coragyps atratus
Sometimes referred to as American Black Vulture, to avoid confusion with the Cinereous Vulture (Aegypius monachus), which is also known as Eurasian Black Vulture or just Black Vulture.
Description
This New World vulture is entirely black, except for the outer primaries on the under- and upperwings (see picture). Its head is unfeathered and somewhat paler than the body and its tail is very short.
Identification
The Black Vulture can be mistaken with the Turkey Vulture (Cathartes aura), but they are easily separated by head, black in Black Vulture and red in Turkey; wing, broader in Turkey; underwing coverts, larger in Turkey; and tail, longer in Turkey. Another good way to distinguish them is the flight: Black Vultures beat their wings more often than Turkey when in flight. The underwing coverts can resemble Southern (Caracara plancus) and Crested Caracara (Caracara cheriway), too, but wing and tail shape separate them.
Distribution
The Black Vulture is very widespread and common, being found throughout almost whole South America, except for far south, Central America, Mexico and southern and eastern United States. Has been recorded as a vagrant on Cuba and the southern Lesser Antilles.
Habitat
It lives in a wide range of habitats from deserts and grasslands to woodland and forest, but the last is often avoided. They are mostly found in open areas, being very common in big cities, e.g. Sao Paulo and Rio de Janeiro, Brazil.
Behaviour
This vulture, as well as most of the others, soars high with dihedral, in large groups or pairs, searching for thermal currents. It searches for food by eyesight and its diet consists mostly of carcasses, but they can feed, in lesser scale, on insects, small mammals and reptiles and eggs. Hundreds of individuals are seen soaring and perched on trashpiles, which together with the ability to nest on skycrapers, makes this species one of the most adaptable to human life. They are often seen taking sun baths with the wings spread.
Taxonomy
Three subspecies exist, but they are not always recognised. Howard & Moore checklist, for example, consider C. atratus monotypic.
- C. a. atratus (North American Black Vulture): USA and northern Mexico.
- C. a. brasiliensis (South American Black Vulture): from central Mexico to Peru and Brazil.
- C. a. foetens (Andean Black Vulture): from Ecuador to central Chile and Argentina.
