How to tell it apart

Listen for:Barn Swallows' song is a constant, cheerful twittering and warbling mixed with mechanical-sounding whirrs and squeaks. It's not a structured melody, more a stream of chatter often ending in a sputtering, high-pitched chirr. They frequently sing in flight or from a perch near the nest. Calls include a sharp 'svit' or 'sweeek' when alarmed (especially if a predator near the nest), and a persistent chattering when congregating. Often written as “Cheery warble with squeaks”.
Don't confuse with:The Cliff Swallow — cliff swallows have a pale buffy rump (patch on the back) and a bright white forehead, with shorter, square tails. barn swallows have a long forked tail and no pale rump patch.

Where you'll hear it

Open areas such as farms, fields, marshes, lake edges, and suburban parks. Often near water which produces insect prey. Nests almost exclusively on human-made structures (barns, under bridges, eaves). Found across North America in summer; winters in Central and South America.

Diurnal. Migrates in day and night (can cross Gulf of Mexico in a long flight). Breeds in spring/summer: pairs cooperate to build mud nests often in colonies. Very active feeding schedule to raise nestlings. By late summer, swallows form big roosting flocks in marshes or on powerlines before migration. In winter (South America), they remain in flocks in open habitats. Known for their graceful, acrobatic flight all summer long.
