Grey-Breasted Martin

This swallow relative is found across open country, farmland and towns from Mexico through much of South America, foraging on the wing for flying insects over fields, water and clearings, often in loose groups. Its brownish-grey upperparts and pale, streaked underparts distinguish it from more colourful swallows, and it frequently nests in cavities in buildings, culverts or dead trees, giving away nest sites with soft, gurgling calls. Warmer months during the breeding season offer the best chance to see groups gathering near nest cavities and feeding actively at dawn and dusk.
