The white-chested swift is a species of bird in subfamily Cypseloidinae of the swift family Apodidae. It is found in Bolivia, Colombia, Ecuador, Peru, and possibly Brazil.
Region
Andes Mountains
Typical Environment
Occurs patchily from Colombia through Ecuador and Peru to Bolivia, with possible records in adjacent western Brazil. Most encounters are over humid montane and foothill forests, river valleys, and steep gorges. It frequently patrols ridge lines and waterfalls where updrafts concentrate flying insects. Roosts and probable nesting sites are on wet, shaded cliffs, often behind waterfalls.
Altitude Range
500–2500 m
Climate Zone
Highland

The white-chested swift is a scarce Andean swift recognized by its striking white chest contrasting with otherwise sooty-dark plumage. It often forages high above humid montane forest and along river gorges, frequently mixing with other swift species. Like several Cypseloides, it is believed to nest on perpetually wet cliff faces, often behind waterfalls. Much about its breeding biology and population size remains poorly known.
Temperament
social and active
Flight Pattern
fast aerial flier with rapid, stiff wingbeats and long glides
Social Behavior
Often forms loose mixed-species flocks with other swifts while foraging. Likely nests colonially or in small groups on constantly wet cliffs and behind waterfalls. Pairs are presumed monogamous for the season, with communal roosting at secure cliff sites.
Migratory Pattern
Resident
Song Description
Vocalizations are high-pitched chips and sharp, thin screams given in flight. Calls carry over valleys and are most noticeable around foraging flocks and roost sites.
Plumage
Mostly sooty to blackish with a clean, contrasting white chest and lower throat; wings long and scythe-shaped with a slightly square tail.
Diet
Feeds on small aerial insects such as flies, ants, termites, and beetles captured on the wing. It takes advantage of updrafts along ridges and cliffs to forage efficiently. Insect swarms after rainfall or near waterfalls are frequently exploited.
Preferred Environment
Most often hunts above the forest canopy, along river corridors, and around waterfalls where insects concentrate. Also forages over open valleys and forest edges in mountainous terrain.
