Checked the reservoir with Paul G and Paul M. 4 adult Yellow-legged gulls, 6 Meds (4 adult, a 2cy and a 3cy).
22 Great-crested grebe was most I've seen. 12 Goldeneye (5m) and pair Goosander. Unfortunately the roost was really late to form, with the majority of the gulls only coming onto the water once the light had almost gone. They eventually formed a good sized roost stretching almost a kilometre from the trout pens to almost the hide but too dark to check thoroughly.
