The pied wagtail is a very common bird and I see them by the stream all the time. This one was sitting high up on a wire and caught my attention because it looked so white. It didn’t have the usual black eye bar either. I wonder whether it’s a subspecies (or maybe I’ve just embarrassed myself and it’s not a pied wagtail after all!).
