Description

A large soaring bird with a wingspan of up to 72 inches. They are almost entirely blackish-brown with a featherless red head. In flight, they are easily identified by their 'dihedral' (V-shaped) wing profile and unstable, rocking flight style.

Colour & Pattern

Uniform dark chocolate brown to blackish-brown on the dorsal surface, with a silver-gray or pale sheen on the ventral (underside) surface; the rachis is light-colored/creamy at the base

Barb Structure

Pennaceous and tightly interlocked throughout most of the vane; the base (superior umbilicus) shows soft, plumulaceous (downy) barbs for insulation

Texture & Surface

Relatively stiff and matte; the surface is designed for durability during long-duration soaring and lacks the oily sheen or silent-flight adaptations of other large birds

Key Features

The distinctive silver-gray sheen on the underside of the dark brown vanes and the pale, stout rachis are diagnostic for Turkey Vulture flight feathers

Habitat

Open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts; often nests in rock crevices, caves, or hollow logs

Geographic Range

Common throughout the Americas, ranging from southern Canada to the southernmost tip of South America; northern populations are migratory

Ecological Role

Scavenger; they provide a critical ecosystem service by consuming carrion, which helps prevent the spread of diseases like anthrax and rabies

Similar Species

Black Vulture (feathers are shorter and lack the strong silver-gray ventral contrast) and Juvenile Bald Eagle (feathers usually show white mottling or a different texture/sheen)

Interesting Facts

Unlike most birds, Turkey Vultures have an incredibly keen sense of smell, allowing them to locate carrion hidden under forest canopies from high in the air

Condition Notes

Good condition; shows some minor feather wear and 'nicking' at the tips consistent with a naturally molted feather from an adult bird
