Guinea fowl (Numida meleagris), bird that resembles a turkey and has been domesticated since Roman times. It is distinguished by a naked head and dark gray, spotted plumage. Wild guinea fowl live in Africa and Madagascar, moving about woods or grassland in flocks. They are eaten in some places, but run from danger, rather than fly, and attempts to raise them as game birds have, therefore, failed. They do fly up into trees to roost.
