The lesser yellow-headed vulture (Cathartes burrovianus) also known as the savannah vulture, is a species of bird in the New World vulture family Cathartidae. It is found in Mexico, Central America, and South America in seasonally wet or flooded lowland grassland, swamps, and heavily degraded former forest.
The turkey vulture (Cathartes aura), also known in some North American regions as the turkey buzzard (or just buzzard), and in some areas of the Caribbean as the John crow or carrion crow, is the most widespread of the New World vultures. One of three species in the genus Cathartes of the family Cathartidae, the turkey vulture ranges from southern Canada to the southernmost tip of South America.
