Which bird of prey can locate carrion partly by its highly developed sense of smell?

The turkey vulture can locate carrion partly by using its highly developed sense of smell.

This ability is unusual among birds and helps turkey vultures find dead animals beneath forest canopies or in other places where vision alone is less effective. They often fly low while searching, then descend when they detect suitable food. Their bare, reddish head and dark body give them a turkey-like appearance, which inspired the common name.

Turkey vultures are widespread in the Americas, ranging from southern Canada to the southern tip of South America. They are important scavengers because they remove carcasses and consume tissues that could otherwise support disease-causing organisms.

The species is sometimes confused with the black vulture. Black vultures rely more heavily on sight and on following other vultures to food. Turkey vultures also soar with their wings held in a shallow V and frequently rock from side to side in flight, a behavior called tilting or wobbling.
