The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world. It is a distinctive passerine bird with blue upperparts and a long, deeply forked tail. It is found in Europe, Asia, Africa and the Americas. It builds a cup nest from mud pellets in barns or similar structures and feeds on insects caught in. The Pacific swallow (Hirundo tahitica) is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. The Pacific swallow builds a neat cup-shaped nest, constructed with mud pellets.
