Scientific name: Coragyps atratus
Not very closely related to Turkey Vultures, the Black Vulture lacks the highly developed sense of smell that makes Turkey Vultures so efficient at finding carrion. They instead often use their aggressive temperament to take over a carcass located by their distant relative. Black Vultures are largely non-migratory, but may withdraw from northern portions of their range in winter.
Black Vultures are aggressive not only at food sources where older birds dominate younger birds, but also at communal roost sites. Birds unrelated to each other are more aggressive, and related birds sometimes gang up on non relatives.
