The barn swallow is the most widespread species of swallow in the world, occurring on all continents, with vagrants reported even in Antarctica. It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail. In Anglophone Europe, it is just called the swallow; in northern Europe, it is the only member of family Hirundinidae called a "swallow" rather than a "martin".
Region
Northern Hemisphere (breeding) and tropical/subtropical regions worldwide (wintering)
Typical Environment
Breeds across temperate North America, Europe, and much of Asia, favoring open country with scattered trees, farmland, meadows, and settlements. Frequently nests on buildings, inside barns, and under bridges, placing mud cup nests on beams or ledges. Winters widely in Central and South America, sub-Saharan Africa, South and Southeast Asia, and parts of Oceania. Occurs in most regions except Antarctica, though it can appear as a rare vagrant in extreme locales.
