Stone Partridge (Pterocles petrosus) (Swainson, 1837)
Nahan's Partridge (Acentrortyx nahani)

Ptilopachinae is an African genus of birds in the pheasant family. As traditionally defined, only the Stone Partridge was included in this genus, but based on genetic evidence it now also includes the Nahan's Partridge (formerly considered a francolin). The study also concludes that this genus is more closely related to the New World Quail,[1][2][3] but many taxonomists still include this with the Phasianidae. At about 25 centimetres (9.8 in) in length, both are relatively small, terrestrial birds with a red eye-ring, base of the bill and legs, and brownish upperparts.[4]
