White Wagtail sp. Who Are You?
It's a White Wagtail sp., but I can't tell which. It is grey from the head to the uppertail coverts with no black at all. There is no eye-stripe, and the apron on the breast is mottled. My first impression when I found it was a first-winter Black-backed Wagtail, but when I looked through the binoculars it was much whiter and felt wrong.
I'm not quite sure what this is. For now I'll call it a White-faced Wagtail, female, first-winter.
The black apron on the breast is almost entirely absent. Whether this falls within individual variation for White-faced Wagtail or represents a colour morph, I'm not sure….
