While I was out for a walk yesterday, I heard this bird singing in the shrubbery beside the road. I could see his indistinct shape fluttering around deep in the foliage but there was just no photo opportunities. I spent 20 minutes or so standing there with my camera at the ready in case he decided to show himself. He finally popped out and I managed to grab a few shots before a passing car scared him back into hiding. These are supposedly a very common warbler but I don't see them all that often and they are very hard to photograph.
