Barn Swallow

The Barn Swallow (Hirundo rustica) is the most widespread species of swallow in the world.[2] It is a distinctive passerine bird with blue upperparts, a long, deeply forked tail and curved, pointed wings. It is found in Europe, Asia, Africa and the Americas.[2] In Anglophone Europe it is just called the Swallow; in Northern Europe it is the only common species called a "swallow" rather than a "martin"
