The bird that has become emblematic for Ghana and neighboring countries in West Africa is this Picathartes, defined as "gymnocephalus" ('naked head') - for obvious reasons because it largely lacks feathers on its head. It is also called White-necked rockfowl or Yellow-headed Picathartes. It is a fairly big passerine (38 to 41 cm or 15 to 16 inches long). The species has been classified as "vulnerable" because its habitat is threatened by deforestation and hunting. Its strange appearance is matched by equally deviant behaviors: it rarely flies, jumps more on the ground; it builds its nests of mud, usually attached to rock walls; it has two mating seasons but then lays only two eggs, and so on. It raises its young on small amphibians and insects but also follows armies of ants that make insects take wing and thus become easy prey.
