A walk round today with our 2 teenage grandchildren. In Cogan Wood Flynn & I had a nice encounter with the local Marsh Tit by the dragon tree. A GS Woodpecker was heard calling there, and a Buzzard was sitting up high in a tree. At W lake there had been an arrival of Swallows, with 30+ feeding over the lake and a single House Martin was with them. Another GS Woodpecker drummed briefly in the wood near the Medieval Village. Snapped a bumblebee sp on Hawthorn blossom in W paddock.
