Guinea Fowl

Guinea fowl are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. Phylogenetically, they branched off from the core Galliformes after the Cracidae and before the Odontophoridae. An Eocene fossil lineage Telecrex has been associated with guinea fowl; Telecrex inhabited Mongolia, and may have given rise to the oldest of the true phasianids, such as blood pheasants and eared pheasants, which evolved into high-altitude, montane-adapted species with the rise of the Tibetan Plateau. While modern guinea fowl species are endemic to Africa, the helmeted guinea fowl has been introduced as a domesticated bird widely elsewhere.
