Forages over any kind of open or semi-open terrain, especially near water. Breeding was formerly limited by scarcity of nest sites in natural caves or sinkholes. Now nests under bridges and in culverts, buildings, silos, many other artificial sites, allo
wing species to spread into new habitats.
Nest: Natural site is on steep wall of cave or sinkhole, in area away from entrance but with at least some light. Artificial sites are on vertical surfaces in culvert
s, under bridges, or in buildings; in Yucatan Peninsula, may nest in ancient Mayan temples. In well-sheltered sites, nests may last for years and be used repeatedly. Nest (built by both sexes) is an open cup of mud plastered against wall. Birds in natural
sites gather mud on cave bottom, where it often contains much bat guano. Nest is lined with grass, bark fibers, plant down, and feathers.
Eggs: 3-4, sometimes 2-5. White, finely spotted with brown and purple. Incubation is probably by both parents, thought to be about 15 days.
Young: Both parents bring food for nestlings. Young leave nest at about 20-26 days.
Behavior: Forages almost entirely in flight, pursuing flying insects and eating them in the air. May forage low over water or may forage much higher, mainly in clear warm weather. Often forages in flocks.
nests under bridges. Rapidly expanding range. Accidental in southern Arizona. Individuals have been seen north to dash line in Texas.
