The Barn Swallow has blue upperparts, a reddish face and underparts, and a deeply forked tail. It catches flying insects over open ground and water, often close to the surface. Its open cup nest is made from mud and is now usually attached to buildings, bridges and other structures. Northern populations migrate long distances and winter across much of the Southern Hemisphere. It is the most abundant and widely distributed swallow species in the world.
Locations where this species is supported by a dated first record, an unambiguous single-place outing or a reviewed assignment.
