During this time of year, you may notice clusters of jug-shaped, plaster-textured nests on the undersides of cliffs or manmade structures. If you've seen these settlements, you've probably also seen the small, pointy-winged birds they belong to: cliff swallows. A migratory bird, the Cliff Swallow (Petrochelidon pyrrhonota) is common in the Bay Area during the summer breeding season, its breeding range stretching all the way from Alaska to southern Mexico. |
