This very large swift builds a saucer nest of mud, moss and chitin on a ledge in a cave, usually behind a waterfall, and lays two white eggs between March and July. It breeds in the mountains and foothills, but forages over a much larger area, including lowlands.
White-collared swift is a massive and powerful species, 20–22 cm (8-8.8 in) long, and weighing 90-125 g (3.2-4.5 oz.) It has a very slightly forked tail, which often appears square. The adults are black, glossed blue on the back, and have a white collar, broader and duller on the breast than the hindneck. Young birds are duller than adults, and the collar is reduced or absent. This noisy swift has a screeching chee-yar! call, which may be given in chorus by a flock
This is a highly gregarious species, with flocks of 100 or more birds, and often in company with other swift species. It has a powerful, fast and direct flight, and will ascend thermals to great heights.
