Why are there no feathers on that bird’s head?

Adult California condors have a distinctive pink head and neck that is bare of feathers. That bare head is perfectly designed to keep rotting food from sticking to it as the birds eat. The skin on an adult condor’s head can also express some emotions. It turns a deep red-pink during courtship or when the birds are excited or alarmed. The adults also have a throat sack that they can puff out during courtship displays.
