Distribution. This replaces the last species in the extreme North-west of India, and is the common bird of the Punjab, Sind, and Cutch, extending east to Delhi; farther east than this yellow-billed birds prevail. N. percnopterus ranges through Baluchistan, Afghanistan, and Persia to Egypt and Southern Europe, and has an extensive range in Africa. The occurrence of a single bird was observed by Biddulph at Gilgit. Of course, there is some passage between the two Neophrons, which are mere geographical races scarcely deserving specific distinction.
