Do vultures find their food by smell or sight?
All vultures find food with their incredible eyesight, but new world (American) vultures have a keenly developed sense of smell, on which they rely for most of their foraging. Turkey vultures use an even combination of smell and sight–whichever reaches them first. The rest of the new world vultures rely partially on smell and more on eyesight, or the activities of turkey vultures. Old world vultures have no sense of smell, and rely solely on eyesight.
