Древесный стриж/Crested treeswift (Hemiprocne coronata) - A beautiful swift with a crest

This treeswift has a crest and a long, deeply forked tail. The adult male has orange cheeks and ear coverts with a narrow streak of white under the eye and a trace of a white supercilium. The female has a thin white stripe below the eye running along the cheek. Young birds have a dark grey head and wings but the feathers are edged in white and the rest of the soft plumage is much streakier than that of the adults.

The call of this species is a harsh kee-kyew or three note kip-kee-kep with emphasis on the middle note. The crested treeswift is a common resident breeder from the Indian subcontinent.
