Cliff Swallow - Petrochelidon pyrrhonota

The Cliff Swallow is also known as the American Cliff Swallow and the North American Cliff Swallow. They breed throughout North America and winter in South America.

A good place to see them and get fairly close is at the Hayward Regional Shoreline in Hayward, CA. They nest near the Interpretive Center and farther down the path at a small bridge. Cliff Swallows build their nests from mud. It is interesting to see them gathering the mud at Hayward.
