GALLINAE

Gallinae is the Gallinaceous order of birds. They are characterized by a vaulted upper mandible, the nostrils pierced in a large membranous space at the base of the beak, and covered by a cartilaginous scale. They have three toes in front, and one behind, sometimes articulated high on the tarsus. The claws are stout, short and slightly curved.
