The Costa Rican swift (''Chaetura fumosa'') is a species of swift in the Apodidae family. It was split from the band-rumped swift, ''Chaetura spinacauda'', in 1998. It is found in Colombia, Costa Rica, and Panama with a natural habitat of subtropical or tropical moist lowland forests. It is blackish and slim-winged with sharply contrasting pale-rump band and distinctly pale throat. It has a sooty black coloration is tinged with glossy blue. Its bill and feet are black in comparison to the band-rumped swift. Costa Rican Swifts usually feed on insects in flight over open habitats and agricultural fields, although this species sometimes can be found over forest and semi-open habitats. It is usually found in groups of 5–10, but they form flocks of up to 50 after breeding season. It associates with other small swifts such as the gray-rumped swift, the band-rumped swift and the Vaux's swift where ranges overlap and where feeding is good. It nests in tree hole 30 ft. up in any sort of tree. ==References==
