I'll say a sand martin.
Black-tailed Godwit
really hard. I'm thinking some sort of pipit, but that tail seems to be too plain, other thoughts are out as the legs look very dark. I'll try water pipit then.
I'll try Corn bunting
No p taking please but I'll try a wheatear

I'm just going to say that the legs aren't really as dark as they look and say song thrush.
