Cliff Swallow Nest Building

A bridge in the middle of upper Bidwell Park hosts an impressive group of Cliff Swallows who are now in the midst of piecing together their nests. I had never seen such a dense group of nests and was amazed by how close together they manage to frantically zoom in and out from under the bridge with no problems at all.


Pairs seem to switch back and forth on the construction of the nests
