Wagtails at Marloes Mere

At times stunning views of the male Blue-headed Wagtail at Marloes Mere, but wow, how difficult are wagtails to digiscope with a hand held camera (excuse for the poor shots)?!  At least 3 other Yellow Wags in the same field, possibly 4, 2 male flavissima, and a female that had a really white super and greyer tones around the head, and associated with the male Blue-headed.  14 Whimbrel at the Gann.
