Swift Swifts

My dad and I sat on his front porch last week and watched a large flock of chimney swifts feeding on insects, as they flew as erratically as bats. They remained high overhead. I only caught a small portion of them in this picture and, even though I zoomed, they were  high, as I said. But you can get the idea, or you can click on the picture to get a better idea.

It was quite a "herd of birds!"
