The Black Vulture is a common bird throughout the southern US, ranging as far west as Arizona. It is easily recognized and distinguished from its cousin, the Turkey Vulture, by its all-black head (although young Turkey Vultures also have dark heads). In flight, Black Vultures flap their wings much more than Turkey Vultures, and the white patches in the primaries and very short tail also quickly identify them. This one was photographed near a road kill along a road in southern Florida. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 64 film. (Date: November 1979)
