Bank swallows are one of seven species of swallows found in North America. This particular colony was located on a sand cliff beneath a bald eagle's nest. I doubt that they got any benefit from the eagle but I don't think the big raptor was any danger either.
I filmed these birds at both a regular speed and at a slow speed. I am always amazed at how much more there is to see when you slow down video. The grace of these birds is even more evident.
