In addition, we also recorded a couple of Cormorants, sitting in the trees by the bottom reservoir, 1 "redhead" Goosander, 1 Great-crested Grebe, 5 Coots, 8 Moorhens, 50 Black-headed Gulls and this interesting looking duck.
My initial reaction was a juvenile Wigeon, which is what I recorded it as. It was dabbling and feeding on seeds under the trees on the middle reservoir, and it was only when I got back and looked at the pictures of the computer, that I noticed it had an all black beak, something that is not shown on images of juvenile Wigeon. I'll leave it as that unless anyone else knows better?
The final birds of note were a small flock of Redwings (c.6) and Fieldfares (c.10) that flew up from Rowans by the top reservoir.
