Grey Wagtail

Grey? GREY?!?! Well okay, they are on the back, but that flash of yellow is most definitely more colourful than the name suggests, and the bobbing motion of the tail as it flits about is unmistakeable. Often seen by water skipping between rocks. It has amber status. The RSPB has more info.
