American Cliff Swallow Petrochelidon pyrrhonota
There has for several years been an active Cliff Swallow colony at the Fountain Street bridge over the Grand River in Cambridge, ON. Today we paid a visit and were delighted to see that the swallows have returned for yet another season and were actively involved in building their nests. There is an abundance of mud at the river's edge and the girders on the underside of the bridge make for an ideal nesting site. Interestingly, an American Robin had located its nest next to a swift nest, and in the past we have seen Rock Doves nesting in the same vicinity.
