Comments: Feeds on small flying insects; catches insects in the air. Feeds in long, continuous foraging flights high over varied habitats; also at lower levels over forest openings, burns, rivers and lakes (Grinnell and Miller 1944). In Oregon, foraged up to 5.4 km from the nest but mostly near the nest stand (Bull and Beckwith 1993). Often joins other swifts in feeding at edges of rainstorms (Stiles and Skutch 1989; Campbell et al. 1990). Feeds on leafhoppers, true flies; see Bull and Beckwith (1993) for extensive information on diet in Oregon.
