Cool Facts
- The Barn Swallow is the most abundant and widely distributed swallow species in the world. It breeds throughout the northern hemisphere and winters in much of the southern hemisphere.
- The long tail of a Barn Swallow may indicate the quality of the individual bird. Females prefer to mate with males that have the longest and most symmetrical tails.
- An unmated male Barn Swallow may kill the nestlings of a nesting pair. His actions often succeed in breaking up the pair and afford him the opportunity to mate with the female.
- Female Barn Swallows favor males that have a darker reddish chest color.

Conservation

Least Concern
The Barn Swallow has benefited greatly from human activity. Artificial structures have allowed it to move into new areas and nest in higher densities than ever before. As a result, populations are much greater than they were before European settlement of North America. You can help scientists learn more about this species by participating in the Celebrate Urban Birds!
