Elgon francolin: The Elgon francolin ("Scleroptila psilolaema elgonensis") is a francolin found in moorland at altitudes above 2300 m from eastern Uganda (Mount Elgon) to central Kenya.  Most recent authorities treat it as a subspecies of the moorland francolin.  Alternatively, it has been suggested that it is a species ("S. elgonensis"), a subspecies of the Shelley's francolin ("S. shelleyi elgonensis"), or even a hybrid between the moorland and red-winged francolins.  It was described by Ogilvie-Grant in 1891 as "Francolinus elgonensis", and some authorities still use the genus "Francolinus" for all members otherwise placed in "Scleroptila".  The Elgon francolin resembles the nominate subspecies of the moorland francolin, but the latter is duller (less rufescent) and has a black-dotted throat.
