  • Flight, Voice & Habitat

    The active flight of a Black Vulture consists of 3-5 shallow, rapid, stiff wing beats followed by a short period of glide. This vulture flaps its wings more often and more rapidly than a Turkey Vulture. The Black Vulture has heavier wing loading (shorter wings so less surface area for weight) than the Turkey Vulture, requiring stronger thermals for soaring, so they usually become active an hour or more after Turkey Vultures. They are also often seen soaring higher than Turkey Vultures.

    Because of their lack of a voice box, the Black Vulture has no true call. This vulture may hiss or grunt when feeding or disturbed at nest.

    Black Vultures prefer open country wherever carrion is present. Sometimes -- as in the Carolinas -- the Black Vulture shares habitat with Turkey Vultures, but are not as migratory.

  • Nesting

    Black Vultures do not construct a nest, and will sometimes lay their eggs on the ground under a bush. They will nest in thickets, in a hollow tree or log, in caves or occasionally in abandoned buildings. Breeding is in solitary pairs. Eggs are greenish white with brown markings and there are often 2 eggs, rarely 3, differing in size, color, markings and shape. Incubation lasts about 37-41 days and both sexes incubate. Fledglings are ready to leave the nest at around 14 weeks. Nestlings are covered with buff to cream colored down. Age at first flight is about 75-80 days. Black Vultures nest two weeks earlier than turkey vultures and begin breeding around 3 years of age.

  • Distribution

    Black Vultures range from Kansas, Indiana and Pennsylvania, south to southeastern and southern United States and into South America.

  • Food

    Carrion (prefers large carcasses), but also will take weak, sick or unprotected young birds and mammals. Black Vultures have stronger beaks to break up carrion than Turkey Vultures. Black Vultures are more likely to kill an animal (afterbirth and young born) than Turkey Vultures. In some areas, they will eat sea turtle eggs and newly hatched young turtles and raid heron (and other shorebird) rookeries for eggs and young birds.

  • Fun Facts & Other Interesting Information

    Now what did he say? Black Vultures lack a voice box and so their vocal abilities are limited to making raspy hisses and grunts.

    A group of vultures is called a wake, committee, venue, kettle, or volt. The term kettle refers to vultures in flight, while committee, volt, and venue refer to vultures resting in trees. "Wake" is reserved for a group of vultures that are feeding.
