Petrochelidon pyrrhonota

The Cliff Swallow is a compact swallow with a pale forehead, square tail and light patch on the rump. It catches flying insects over open land and water. Colonies build enclosed mud nests under cliffs, bridges, buildings and culverts. A single nest may require hundreds of individual mud pellets. Large colonies provide information about feeding areas but also support more parasites.
