Swallows typically build their nests in sheltered locations, such as under eaves or bridges, or in holes in trees or rocks. They are insectivorous, and their diet consists mainly of flying insects, such as flies, mosquitoes, and wasps.
Some common species of swallows include:
* Barn swallow (Hirundo rustica): This species is found in North America, Europe, Asia, and Africa. Barn swallows are known for their distinctive red throat and forked tail.
* Tree swallow (Tachycineta bicolor): This species is found in North America and Central America. Tree swallows have a bluish-green back and white underparts.
* Cliff swallow (Petrochelidon pyrrhonota): This species is found in North America and South America. Cliff swallows are known for their mud nests that are built on vertical surfaces, such as cliffs or buildings.
* Bank swallow (Riparia riparia): This species is found in North America, Europe, Asia, and Africa. Bank swallows are small swallows with brown upperparts and white underparts. They nest in colonies in burrows that are dug into the ground.
