Peek-a-boo

These blue tits were nesting in this post. Feeding chicks is a non-stop business, I watched two of them fly in and out continually for about five minutes. I managed to catch this one on exit, by having the camera on sports mode and taking about 100 photos. Even then, he was gone in the next photo, they're so fast. I wonder if anyone thought I was odd, standing there photographing an old post on sports mode...
