Onychognathus
Onychognathus is a genus of starlings, most of which are found in Africa.
All the species are quite similar, and characterised by rufous primary wing feathers, very obvious in flight. The males are typically mainly glossy black, and the females have dull grey heads.
The genus was introduced by the German physician and ornithologist Gustav Hartlaub in 1849 with the chestnut-winged starling as the type species. The name Onychognathus combines the Ancient Greek words onukhos "claw" or "nail" and gnathos "jaw".
