Old World quail
Several species of pheasant like birds
"Old World quail" is a collective term for several unrelated genera of smaller galliform species under the tribe Coturnicini of the subfamily Phasianinae. Note that although species which are commonly referred to as "Old World quail" fall in the same tribe, they are paraphyletic with respect to the other genera of the tribe, such as Alectoris, Tetraogallus, Ammoperdix, Margaroperdix, and Pternistis. New World quail are also housed in the order Galliformes, but they are classified under a different family, Odontophoridae.
