Francolins are birds in the tribe Gallini that traditionally have been placed in the genus Francolinus, but now commonly are divided into multiple genera.[1]
As previously defined, they were paraphyletic as the genus Pternistis, which was previously included in Francolinus, is more closely related to Old World quails than it is to the other francolins. Beginning in 2004, various ornithologists have recommended that it would be clearer to use "spurfowl" for all members of the genus Pternistis and restrict the use of "francolin" to the other species presently or formerly classified in Francolinus.[2] When Pternistis is excluded, the francolins form a monophyletic clade that is a sister group to a clade comprising the junglefowl (Gallus) and the bamboo partridges (Bambusicola); together, these clades compose the tribe Gallini.[1]
Although formerly classified in the partridge subfamily Perdicinae, this classification is no longer supported, and they are now classified in the subfamily Pavoninae.[1]
Francolins are terrestrial (though not flightless) birds that feed on insects, vegetable matter and seeds. Most of the members have a hooked upper beak, well-suited for digging at the bases of grass tussocks and rootballs. They have wide tails with fourteen rectrix feathers. Most species exhibit spurs on the tarsi.[3]
