The
Cave Swallow is found in much of Texas and in southern New Mexico in the
United States, and is also found in parts of Mexico, Cuba, and other
locations in the Caribbean. In the United States, they are perhaps
best known from the very large colony found in Carlsbad Caverns in New
Mexico, a habitat they share with Mexican Free-tailed Bats. As a
species they have likely benefited from a human presence. Highway
underpasses and other bridges and man-made structure provide more suitable
nesting locations than were naturally present before man came on the scene.
Habitat: Found in a variety of open habitats as
long as suitable nesting environments are available. Nesting
environments traditionally were caves or other crevices and protected stony
places, but now include many man-made structures as well.
Diet: Feeds on insects
Behavior: Forages for insects while in flight.
Nesting: The nest of a Cave Swallow is an enclosed
structure of mud and clay, lined with softer vegetative material or
feathers. Nests were traditionally located in protected caves and
crevices. The clutch consists of 3 to 5 eggs. Both parents help to
incubate the eggs and feed the young upon hatching.
Song: The song of a Cliff Swallow is a series of
warbling, buzzy phrases.
Migration: While some birds are permanent
residents, those in the northern part of their range are migratory
Similar Species:
Distinctive from most swallow species, except for the similar
Cliff Swallow, which has a
light-colored forehead and a dark throat.
Conservation Status: Population trends indicate
increasing numbers of Cave Swallows, and there are no major conservation
concerns. The
IUCN lists the Cave Swallow as a species of "Least Concern".
