At least 30 Yellow Wagtail at Toft Newton Reservoir this afternoon and I noticed one was different. I made some notes, not knowing what I was looking at and all my notes confirm that it was Blue-headed Wagtail (Motacilla Flava). Being colour blind is mostly disadvantageous
but it does mean I closely look at all sorts of characteristics and the more pronounced supercilium and darker back, along with the head, confirm the identification.Also;
White Wagtail - 3
Goldeneye - 4
Oystercatcher - 2
Dunlin - 1
Redshank - 1
