As I crouched next to my writing room window to photograph a Red-tailed Hawk on the wire, I was so intent on focusing the shot on the bird rather than the branches and power lines that I didn’t see what else was going on: another hawk had arrived.

It wasn’t until I’d downloaded the photos that I saw those legs in the upper right-hand corner of the image. Maybe there’s such a thing as being too intent on one’s goal.
