Cliff Swallow

Petrochelidon pyrrhonota

The Cliff Swallow breeds in most of North America, even to Alaska, but spends winters in western South America. These are the famous swallows that return to Capistrano. In Southern California, sightings of many species of swallow are common, but the Cliff Swallow is by far, the most numerous. These birds usually nest in colonies, and while cliff faces is where they evolved to exploit for nesting, they have adapted to using buildings to attach their mud nests. This relatively new practice is not always appreciated by two legged species charged with maintaining building appearances.
