クロチュウヒ Circus maurus

A striking, mostly dark harrier with large white panels in the underwings, a white rump, and bands on the tail. The juvenile is brown with white flashes in the underwings and has a heavily-streaked chest. It quarters low over heath-like fynbos, semi-desert Karoo, and dune brush hunting for small birds and mammals. Regularly disperses irruptively north into grasslands and steppe from January to July.
