Descrizione Amur Falcon

The Amur Falcon, formerly Eastern Red-footed Falcon, is a small raptor of the falcon family. It breeds in south-eastern Siberia and Northern China, wintering in Southern Africa. Males are characteristically dark sooty brown, and may offer confusion with melanistic Gabar Goshawk, but the chestnut on the vent should prevent confusion here. Also there may be some superficial resemblance to Sooty Falcon and Grey Kestrel, but those two species both have yellow feet and cere. Separating male Amur and Red-footed Falcons is best done by the white underwing coverts on Amur Falcon, whereas the underwing of male Red-footed Falcons is uniformly grey.
