Black guineafowl
The black guineafowl, (''Agelastes niger''), is a member of the guineafowl bird family. It occurs in humid forests in Central Africa where it is often heard but seldom seen. It is a medium-sized black bird with a bare pink head and upper neck. Little is known of its behaviour.
==Description==
The head and upper neck of an adult black guineafowl are unfeathered, revealing the pink skin. There is a crest of short downy feathers on the forehead and crown and the throat and lower neck have a scattering of downy feathers. The body and tail feathers are black with some paler speckled markings on the belly. Males have one to three spurs on their legs while females either have none or a single short spur. Juveniles are similar but have buff tips to the feathers on their upperparts, a speckled breast and white belly. The beak is greenish-grey and the legs greyish-brown. Males are usually slightly larger than females and measure about in length, weighing about . The call is a monotonous high-pitched "kwee" repeated at the rate of two to three notes per second. The alarm call is an even shriller sound repeated more rapidly.
