The Cliff Swallow is a small bird known for its distinctive, forked tail and iridescent blue-black upperparts. It has a pale underbelly and a unique, white throat patch. These birds are often found in colonies, building their characteristic mud nests under bridges, eaves, and cliffs, which is how they got their name. Cliff Swallows are skilled fliers, primarily feeding on insects caught in mid-air. They are migratory birds, traveling long distances between their breeding grounds in North America and wintering areas in South America. Their social behavior and nesting habits make them fascinating subjects for birdwatchers and researchers alike.
