Numbers as follows: Mallard (55), Mandarin Duck (c.30), Coot (6), Moorhen (4), Tufted Duck (12), Great-crested Grebe (1), Grey Wagtail (1), Pied Wagtail (1), Cormorant (2) Kingfisher (1) and Black-headed Gull (15).
As well as the WeBS walk, we also checked and cleaned out the last few nestboxes in time for next year's breeding season. A lovely surprise find of a hibernating bat in one of the boxes was very good. I can't identify the species, but I've sent this photo off to the Derbyshire Mammal Group, so hopefully they'll be able to let me know what it is.
Brown Long-eared Bat
UPDATE: I've just received an email from Steve at the Derbyshire Bat Conservation Trust who identified the bat as a Brown Long-eared Bat - a first for me and possibly Linacre too!!
