Also known as the collared sand martin, the bank swallow (Riparia riparia) belonging to the family of Hirundinidae, order Passeriformes, and genus Riparia, are the smallest species of swallows native to North America. The bank swallows derived their name as they live in banks and bluffs and are categorized under the Hirundinidae family of swallows.
They can be found in low-lying areas near water bodies with an erosive mantle like river banks, ponds, and streams moving around in flocks. Even during migration, they mingle with several species of swallows and leave North America during extreme winters.
Migration usually takes place during the daytime. However, it's not easy to trace one if you stay somewhere in California or New York.
During the breeding period, both partners indulge carefully in finding out appropriate breeding grounds. The adults form nesting colonies in river bluffs, sandbanks, gravel quarries, and even in mines.
Normally the males are entrusted with the task of digging a burrow with the help of their feet, beak, and wings after which the nests are constructed deep underneath the burrow.

Did you know...
The name swallow has colloquial roots, used to refer to the common barn swallows. These birds constructed their nests in barns.
The period for migration is usually in May, August, and September. Usually, in early August these birds form large flocks with other species of swallows, like barn swallows, tree swallows, or cave swallows, and head towards the southern parts of the United States and towards South America to spend the winter.
The bank swallows return to North America around early spring.
The males try to woo the females by creating their burrow. Then, in pursuit of the females, they take flight, sing, and hover over the burrow entrance to mark their territorial circle.
They are adept at foraging both in the air as well as on the land surface. Moreover, the swift and thrifty wingbeats allow them to catch their prey from about a height of 50 ft above the ground or water surface.
A great resemblance can be noticed between the bank swallows and northern rough-winged swallows. The only distinguishing factor is that the latter lacks the dark brown breast band as well as the forked tail.
Conservation efforts are being taken up by the Iowa Natural Heritage Foundation, Pheasants Forever, and other institutions to secure the sustenance of these birds. Bank Swallow Bend is a nature park situated in Indianola, Iowa where bird watchers and nature lovers enjoy hiking. It is a haven for the colonies of bank swallows.
