There was a birder in the hide when I got there, unusual. He hadn't seen anything, not unusual. A glance out of the hide put me on to a juvenile Coot, strange, they haven't bred to my knowledge. Closer look, ah, not a juvenile Coot, small grebe, unusual. Closer scrutiny showed it to be a Black-necked Grebe, and a juvenile by the slightly yellowy, gold tint to the ear coverts. Nice one.
