American Cliff Swallow

The American Cliff Swallow is a small bird known for building large, communal mud nests on cliffs, bridges, and other structures across North America. They are social birds that often gather in large colonies, which can contain thousands of nests. Their plumage is typically dark brown and white, and they are excellent flyers, catching insects in mid-air for food. These swallows play a vital role in controlling insect populations and are important indicators of environmental health. They are adaptable, often nesting in human-made structures, and exhibit strong social behaviors within their colonies.
