The American black swift, or more simply black swift, is a species of bird that is found from northern British Columbia in Canada through the United States and Mexico to Costa Rica and Brazil. They are also found in the Caribbean.
Region
Western North America to northern South America and the Caribbean
Typical Environment
Breeds locally from coastal and montane sites in western Canada and the western United States south through Mexico, with additional populations in the Caribbean and parts of Central America. Outside the breeding season, it occurs from Middle America to northern South America. Prefers rugged landscapes with sheer, wet cliffs near waterfalls or sea cliffs for nesting. Foraging occurs over forests, canyons, coastlines, and above ridgelines, often at considerable heights. The species is patchily distributed due to its specialized nesting requirements.

The American black swift, often just called the black swift, nests on wet, often shaded cliff faces and behind waterfalls—one of the most specialized nesting habits among North American birds. It spends most of its life on the wing, catching aerial insects high over forests, coastlines, and mountains. Breeding colonies are small and discreet, making the species hard to detect and monitor. Northern populations migrate to wintering grounds in Central and South America.
Temperament
social and active in flight; discreet and wary near nests
Flight Pattern
strong flier with swift, direct flight and long glides at height
Social Behavior
Often forages in loose flocks with other swifts and swallows. Nests in small, loose colonies on wet cliffs or behind waterfalls where it adheres a small nest to rock with moss and mud. Pairs are seasonally monogamous; both parents incubate and feed the single chick.
Migratory Pattern
Partial migrant
Song Description
Vocalizations are high-pitched, thin chips and trills, often given in flight near colonies. Calls can be sharp and piercing but are generally less varied than many songbirds.
