Identify

Afternoon all,

For some reason I thought I'd blipped yesterday but senility must have kicked in cause I hadnt. 
Went for a good walk with Mini G, spotting things as we walked and identifying them ...except for this bird.
Google says its an American Redstart but I saw the pic of it and irs not. I saw a pic of a Grey Wagtail and thnk it's that . So my ever knowledgeable blippers.... what is it? It scooted about the stream beside the walk we did.
Mini G seems in fine fetal but it's hard to tell sometimes, tells you she is but doesn't look it. She stayed for a while. 
Bloods now twice a week, once at Doctors once at hospital.  CAHMS coming 3 times a week to take her out walking and a chat, in addition to her Counsellor. 

Have a great day
