The Bank Swallow, which is also known as the Sand Martin, is native to numerous countries throughout the world. The range of this bird is around 10 million square kilometers. The population of this bird is about 46 million individual birds around the world. Currently there is not any concern that the population of this bird will face a significant population decline over the next several years. The Bank Swallow has a current rating of Least Concern as a result of its population and range.
Most pairs in breeding colonies lay their eggs at the same time so that they will be feeding nestlings at the same time. This means there will be a large number of adults searching for swarms of insects, which makes it more likely they will find them.
The scientific name of the Bank Swallow, Riparia, means “riverbank.”
This species originally nested in the steep, sandy banks of rivers but have adapted to using many different man-made excavations.
A group of bank swallows are known collectively as a "foreclosure" of swallows.
