Costa Rican Swift
It is blackish and slim-winged with sharply contrasting pale-rump band and distinctly pale throat. Sooty- black coloration is tinged with glossy blue. Bill and feet are black. Compare with 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. Usually found in groups of 5–10, but forms flocks of up to 50 after breeding season. Associates with other small swifts (see gray-rumped swift, band-rumped swift and Vaux's swift) where ranges overlap and where feeding is good. Nests in tree hole 30 ft. up in any sort of tree.
