The Bank Swallow is very widespread in the U.S., breeding in nearly all of the northern-central U.S., almost all of Canada, and even the greater majority of Alaska. They winter on a small part of the coast of South America, and can be found migrating throughout all of the sections in between those locations.

Identification

The Bank Swallow is a small, thin, aerodynamic bird with long wings and a short tail that fans out in flight. Mature males and females appear the same: a bright snow white belly and chin, with a charcoal gray head, throat stripe, and back. Those gray parts have almost a purple shade to them in the right light, while the flight and tail feathers are a deeper gray or black color. The bill of the Bank Swallow is very small and pointy, and is a shade of gray or black. 

Juveniles appear similar to adults, but are more puffy and wide-eyed. They lack the purple shade to their feathers, instead being a medium gray shade with slight brown accents on the feathers of the wing. The white chin is also not as noticeable and the belly and chest areas are a much dirtier shade of white compared to mature individuals. The song of the Bank Swallow is a bubbly, twittering chatter that sounds like joyful radio static. The common call is a shorter, guttural version of the song.

Habitat

Bank Swallows live in a variety of habitats across open areas and wet areas near bodies of water like rivers, streams, lakes, and man made reservoirs. They forage near croplands and aquatic habitats, usually seen flitting over the water and feeding while in flight over the water. When nesting, the habitat of the Bank Swallow changes to large sandy cliffs or high vertical banks. The birds dig burrows into these cliffs and nest in the end of tunnel-like nesting holes.

Threats to Conservation

Some common threats to Bank Swallows include erosion of the cliffs and banks that they nest on, dams and flood control policies that limit the open waters that they feed from and live near, and coastal development of their habitats. They are also particularly sensitive to human disturbances, and will stress if humans are near their nests either just observing, or worse, developing the area and urbanizing it. Pesticides and the decrease of flying insects which the birds feed on also harm their populations.
