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.

It breeds in the mountains and foothills, but forages over a much larger area, including lowlands. Preferred habitats include mountains, coniferous forests, open forests, and grasslands with scattered trees.
Monogamous. Breeds single or in colonies up to 12 pairs. This very large swift builds a saucer nest of mud, moss and chitin on a ledge in a cave, usually behind a waterfall. The nest is lined with fine grass, moss or dry leaves. They lays two white eggs between March and July. Eggs are incubated by both parents for a period of 30-35 days. The young are usually fed once per day and fledge after about 45-55 days.
White-collared Swift feeds in flight on flying insects, including beetles, bees and flying ants.
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Sedentary throughout range, but some populations migrate. Vargants known from USA and lesser Antilles.
