Definition
A cathartid is a bird belonging to the family Cathartidae, which comprises the New World vultures. These birds are scavengers, feeding primarily on carrion. They are characterized by their bald heads, adapted to prevent bacterial buildup when feeding on decaying flesh. Cathartids play an important ecological role by removing carcasses from the environment, thus helping to control disease. They use their keen eyesight and, in some species, a well-developed sense of smell to locate food. Think of them as essential environmental custodians.
