Taxonomy and systematics
The spot-fronted swift is monotypic.
Description
The spot-fronted swift is about {{convert|14|cm|in|abbr=on}} long and weighs about {{convert|23|g|oz|abbr=on}}. The sexes are alike. They are almost entirely blackish brown with grayish underwings and a white chin. They get their English name from bright white spots on either side of the bill and behind the eyes.
Distribution and habitat
The spot-fronted swift has a scattered distribution. In Costa Rica it is mostly found on the Pacific slope of the Cordillera Central and Cordillera de Talamanca. It is known in Panama from only a few locations and in Colombia and Ecuador from a larger number, though still widely separated. It is almost unknown in far western Venezuela and extreme northern Peru. It mostly inhabits montane forest at elevations between {{convert|1100|and|2200|m|ft|abbr=on}} but has been documented at {{convert|300|m|ft|sigfig=2|abbr=on}} in Ecuador.
Behavior
=Migration=
=Feeding=
Like all swifts, the spot-fronted is an aerial insectivore. In one study nearly all of its prey were Hemiptera (true bugs) and Hymenoptera (bees, wasps, and ants). Flocks of up to about 50 may forage together, sometimes with other swifts.
=Breeding=
The spot-fronted swift's nesting season overall includes at least April to July but varies geographically. It makes a cup nest of moss, ferns, and mud on a vertical rock face near or even directly above water. It lays a single egg. In a Costa Rica study the incubation period was 26 to 28 days and fledging occurred 65 to 70 days after hatch.
