Having spotted the colony of Cliff Swallows under the 528 bridge over Lake Arthur the day before I tried to time being there when they returned from foraging. When I first arrived there were no birds to be seen. Within moments the flock began to arrive. As one parent lands the others all must flutter in place while departing adults swoop away. The play of their shadows on the underside of the bridge caught my eye while I tried to frame and capture the fast action.
