Falco naumanni



The Lesser Kestrel (Falco naumanni) is a small falcon.
This species breeds from the Mediterranean across southern central Asia to China and Bangladesh. It is a summer migrant, wintering in Africa and Pakistan.
It is rare north of its breeding range, and declining in its European range.
The scientific name of this bird commemorates the German naturalist Johann Andreas Naumann.
It is a small bird of prey, 27–33 cm in length with a 63–72 cm wingspan.
It looks very much like the larger Common Kestrel but has proportionally
shorter wings and tail. It shares a brown back and barred grey underparts with the larger species.
The male has a grey head and tail like male Common Kestrels, but lacks
the dark spotting on the back, the black malar stripe, and has grey patches in the wings.
The female and young birds are slightly paler than their relative, but are
so similar that call and structure are better guides than plumage.
The call is a diagnostic harsh chay-chay-chay, unlike the Common
Kestrel's kee-kee-kee. Both sexes do not have dark talons as usual in falcons; those of this species are a peculiar whitish-horn color.
This, however, is only conspicuous when seen birds at very close range, e.g. in captivity.
