“Turkey vultures, in particular, have a very keen sense of smell,” Elphick says.
“Biologists have done experiments where they put a dead chicken under the leaves, in a forest, under the tree cover, and turkey vultures find it.”
Black vultures often live in an interesting partnership with the turkey vultures.
The turkey vultures smell food and circle over it for a while. This circling is a signal to others -- black vultures, turkey vultures, crows and other animals -- letting them know there is food in the area.
