Grey-rumped Treeswift

Hemiprocne longipennis (Rafinesque, 1802)

Grey-rumped Treeswift, Hemiprocne longipennis, is a bird of the Oriental Region and Australasia, ranging from the Malay Peninsula to Sulawesi and the western Lesser Sundas. It belongs to the Hemiprocnidae, the treeswifts, and is part of the order Apodiformes. It is closely allied to true swifts, but unlike them it lives in trees and is often seen resting on branches, power lines and pylons. When it perches, the wing tips cross over the tail. Adult males have a dark grey throat and chest with a white belly, while females lack the chestnut ear coverts.
