This bird of prey was spotted over Fishhook, near Cape Town last February. In my view it is some sort of Goshawk, possibly a melanistic form. Compared to the Red-winged Starling in the picture it is quite large. That probably rules out the Gabar Goshawk. So could it be an African Goshawk or a Black Sparrowhawk? The size points to the latter, but I am unsure. Thanks for any help!
