Amur Falcon

The Amur Falcon breeds in far eastern Russia, Mongolia, and northern China, and is renowned for one of the longest migrations of any raptor, crossing the Arabian Sea in vast numbers en route to wintering grounds in southern Africa, with a major staging area in northeastern India. It closely resembles the Red-footed Falcon in size and general pattern.

Feathers are most likely encountered near massive communal roosts during migration stopovers or near breeding colonies in open steppe habitat.

Recognizing Amur Falcon feathers

• Flight feathers (male): Dark slate-grey above, with underwing coverts more extensively rufous-white than the Red-footed Falcon.
• Flight feathers (female): Grey with dark barring above, paler and more lightly marked than a female Red-footed Falcon in some individuals.
• Tail feathers: Grey, males fairly plain, females finely barred.
• Body feathers: Males mostly slate-grey with rufous thigh/vent feathers similar to Red-footed Falcon; females orange-buff below with a whiter throat.
• Shaft color: Dark grey in males, pale in females.
• Compared to similar species: Nearly identical to Red-footed Falcon; the clearest feather-level clue is the underwing covert pattern, more solidly rufous-orange in male Amur Falcons versus whiter in male Red-footed Falcons — a distinction that can be subtle on isolated feathers.

Adult males are dark slate-grey overall with red legs, cere, and eye-ring, and rufous thighs, closely resembling the male Red-footed Falcon but with more extensively rufous underwing coverts. Adult females are orange-buff below with a whiter throat and grey, barred upperparts. Juveniles resemble females but duller, molting to adult plumage over roughly two years.

Breeds in open steppe, grassland, and light woodland of far eastern Russia, Mongolia, and northern China. An extreme long-distance migrant, funneling through northeastern India in massive numbers before crossing the Arabian Sea to winter across southern and eastern Africa.

Feeds heavily on large flying insects, especially termites and locusts, caught on the wing, supplemented by small vertebrates. Nests colonially in trees, often using old corvid nests. Vocal near colonies with sharp, repeated calls similar to the Red-footed Falcon. A grey or orange-buff falcon feather found near a communal roost site during migration season in South or East Asia, or in southern African wintering grounds, could belong to this species.
