Andes Mountains
Typical Environment
Found along the Andean cordilleras, most commonly in humid and subhumid montane zones. It frequents edges of cloud forest, scrubby slopes, agricultural valleys, and towns. Birds often patrol over rivers, pasture, and open clearings, taking advantage of rising air along slopes. It adapts well to human-modified landscapes where suitable cavities and open airspace are available.

The brown-bellied swallow is a small Andean hirundine often seen coursing low over valleys and ridgelines. It frequently forages in mixed flocks with other swallows, especially Blue-and-white Swallows. Nesting typically occurs in small colonies, using cavities in earthen banks, road cuts, bridges, or building crevices. Its subdued brown underparts make it easy to separate from brighter blue-and-white congeners.
Temperament
social and active
Flight Pattern
agile with rapid wingbeats and brief glides
Social Behavior
Often forms small flocks and mixes readily with other swallow species while feeding. Typically nests in small colonies, placing nests in cavities of earthen banks, cliffs, bridges, or building crevices. Pairs are presumed monogamous during the breeding season and both sexes participate in nest duties.
Migratory Pattern
Partial migrant
Song Description
Gives a series of soft twittering chips and trills in flight, interspersed with buzzy notes. Vocalizations are continuous during group foraging and become more excited near nests.
