The white-chested swift (Cypseloides lemosi) is a species of bird in subfamily Cypseloidinae of the swift family Apodidae. It is found in Bolivia, Colombia, Ecuador, Peru, and possibly Brazil. The white-chested swift, American black swift (Cypseloides niger), Rothschild's swift (C. rothschildi), and sooty swift (C. fumigatus) form a superspecies. The white-chested swift is monotypic.
The white-chested swift is 14 to 15 cm (5.5 to 5.9 in) long and weighs about 28 g (0.99 oz). Both sexes have a notched tail, with the male's notch being deeper. The sexes have the same plumage. Adults have sooty blackish upperparts with a faint green gloss on the crown and back and bluish wings and tail. They are black between the bill and eye. They have a large white patch across the breast that is wider in the middle. The rest of their underparts are paler than the upperparts and slightly brownish. Immatures do not have the white breast band; they are dark slaty gray with white tips to most of the feathers of the underparts.
The white-chested swift is known from widely scattered locations from Colombia's Cauca River valley... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-chested Swift is recorded against all the birds logged in Farallones de Cali National Natural Park (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
