Most species of birds have external nares located somewhere on their beak.

The scales of birds are composed of keratin, like beaks, claws, and spurs. They are found mainly on the toes and tarsi (lower leg of birds), usually up to the tibio-tarsal joint, but may be found further up the legs in some birds.
