The White-collared Swift, "Streptoprocne zonaris", is a resident breeding bird from central Mexico, the Greater Antilles and Trinidad south to Peru, northern Argentina and southeastern Brazil.

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 long, and weighing 90-96 g. 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.

White-collared Swift feeds in flight on flying insects, including beetles, bees and flying ants.
