Amur Falcon

The Amur falcon is a small falcon with long wings, spanning 63–71cm, that reach or just pass the tail tip at rest. Males are dark sooty grey above with rufous thighs and vent, and in flight show a white wing lining against dark flight feathers, unlike the dark grey lining of the male red-footed falcon, its closest relative, of which it was long treated as a subspecies. Females are harder to identify but have an orange eye-ring, a red cere and reddish-orange feet (Wikipedia, general species account).

It breeds in eastern Asia, from Transbaikalia and Amurland to northern Mongolia and North Korea,, and migrates in large flocks on a broad front and crossing the Arabian Sea to winter on the coasts of southern and East Africa. Migrants are thought to be helped by strong westward winds at high altitude (Wikipedia, general species account).
