Elgon francolin explained

The Elgon francolin (Scleroptila elgonensis) is a francolin found in moorland at altitudes above 2300m (7,500feet) from eastern Uganda (Mount Elgon) to central Kenya.^{[1] [2] [3] [4] [5]}

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. It was previously considered a subspecies of the moorland francolin (S. psilolaema), which is now thought to be endemic to Ethiopia. Alternatively, it was suggested as a subspecies of the Shelley's francolin (S. shelleyi elgonensis), or even a hybrid between the moorland and red-winged francolins.^[6] However, it was split as a distinct species by the IUCN Red List and BirdLife International in 2014, and by the International Ornithological Congress in 2022 based on a 2019 study.^{[7] [8]} The Elgon francolin resembles the moorland francolin, but the latter is duller (less rufescent) and has a black-dotted throat, and also differs in vocalizations.
