2 G-c Grebe families on W lake – 1 fem had 2 v small ‘humbugs’ on her back and the other had three slightly larger ones, 2 carried and one on the water. 2-3 Reed Warblers are singing by the main boardwalk, plus a Reed Bunting, and 2-3 more Reed Warblers are in the reeds by the dipping pond. Whilst trying to see one, a Great Spotted Woodpecker flew by, into the trees bordering the car park.
