Five gull species on Upper this afternoon - the obvious LBBG/Herring/BHG plus a single Common Gull and an adult YLG sat on a buoy close to the dam (as Josh mentioned above). Several very good candidates for juvenile YLG on the water too.
Juvenile Linnet x2 in front of the sailing club. Recently-fledged Goldcrest family along the road to the Sailing Club.
More Swallows than I've seen at Bittell recently, particularly feeding low across the fields to the north. Yellowhammer x 2 and Meadow Pipit in this area too.
Worryingly there were three unsupervised children - primary school age, maybe 9/10 years old at most - along the shoreline at the NE corner of Upper around 4pm. Two boys and a girl. The two boys were in trunks as though they'd been swimming. I called over the fence to them to ask whether they knew they were trespassing. They said they didn't know, apologised and said they were leaving. I wonder whether their parents knew where they were.
