Black Vulture


With sooty black plumage, a bare black head, and neat white stars under the wingtips, Black Vultures are almost dapper. Whereas Turkey Vultures are lanky birds with teetering flight, Black Vultures are compact birds with broad wings, short tails, and powerful wingbeats. The two species often associate: the Black Vulture makes up for its poor sense of smell by following Turkey Vultures to carcasses. Highly social birds with fierce family loyalty, Black Vultures share food with relatives, feeding young for months after they’ve fledged.

In the U.S., Black Vultures are outnumbered by their red-headed relatives, Turkey Vultures, but they have a huge range and are the most numerous vulture in the Western Hemisphere. One-on-one at a carcass, Black Vultures lose out to the slightly larger Turkey Vulture. But flocks of Black Vultures can quickly take over a carcass and drive the more solitary Turkey Vultures away. Black Vultures lack a voice box and so their vocal abilities are limited to making raspy hisses and grunts. Although Black Vultures and their relatives live only in North and South America, the oldest fossils from this group—at least 34 million years old—were found in Europe.
