Systems

• Terrestrial

Comments: Arid open country, deserts, sagebrush plains, dry barren foothills, canyons, and cliffs, around ranches, rural homes. In far north inhabits tundra and shrub tundra. Nests in cliff crevices, holes in banks, sheltered ledges, tree cavities. Also nests under bridges, in mines, under roofs, etc.

Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.

Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.

Highly migratory in Canada and most of U.S. Occurs throughout the year in Mexico and part of southwestern U.S.

Comments: Primarily eats insects (e.g., bees, wasps, ants, flies, beetles, butterflies), and other invertebrates (e.g., sow bugs, spiders, millipedes). Also feeds on some berries.

Observations: The same female was observed nesting for over 5 years (http://bna.birds.cornell.edu/).

Clutch size is 3-7 (usually 4-5). Incubation, by female, lasts 12-14 days. Altricial, downy young are tended by both parents, leave nest in about 14 days. Male may tend first brood while female renests.

The following is a representative barcode sequence, the centroid of all available sequences for this species.

There is 1 barcode sequence available from BOLD and GenBank.   Below is the sequence of the barcode region Cytochrome oxidase subunit 1 (COI or COX1) from a member of the species.  See the BOLD taxonomy browser for more complete information about this specimen.  Other sequences that do not yet meet barcode criteria may also be available.
