Distribution:
Breeds
from Alaska and portions of Canada, south to central Mexico, western Texas,
Missouri, and portions of southeastern United Staes. Winters in South America.
Habitat:
Found in open to semi- wooded habitat
(such as cliffs, canyons, and farms) near meadows, marshes, and water.
Diet:
Primarily insectivorous
; often feeds on small,
swarming insects. Eats beetles, flying ants, wasps, grasshoppers, mosquitoes,
and other insects.
Ecology:
gregarious
at all seasons. Constructs
nest on cliff, or under bridge, culvert, or eaves. Nests in colonies of up to
1000+ individuals (few hundred is average). Catches prey in air. Forages usually
within 0.5 km of colony, but will sometimes travel several kilometers. Periodically,
populations may decline drastically due to prolonged spring or summer rains
and reduced food availability. Parasitic swallow bug is sometimes abundant enought
to reduce reproductive success in large colonies.
Reproduction
Both parents incubate
2-6 eggs (usually 3-5),
for about 12-14 days. Young are tended by both parents, and are able to fly
at 23 days. Female usually produces 1 brood
/year; a few have a second
brood.
