Cliff Swallows in flight

Having been absent for several years, a veritable mob of Cliff Swallows have returned to my friend's property by the Arkansas River near Canon City. I enjoy watching them fly, zipping by at high speeds, twisting and turning in dizzying ways. I also find it a challenge to photograph them in flight and these are 3 of my favorite photos I got this week.

The wings on the bird in the middle photo are out of focus because there is a very narrow dept of field in such rapidly moving birds that camera's can only capture a small portion in focus. But I thought it made an interesting photo anyway.
