Fourteen Teal and two Green Sandpipers present on the lake this morning. The lake is becoming severely silted up and overgrown with reedmace and Himalayan Balsam to the extent that the whole ecosystem is changing to more of a muddy wetland and most of the remaining water is now so shallow that even the Green Sandpipers can walk across it. Only the bottom end is still deep enough for ducks to swim in. It will be interesting to see how this change affects the balance of wildlife over the next year or so. Other birds of interest this morning were two treecreepers, the first I have seen here for about four years, a peregrine, which frightened the living daylights out of the pigeons feeding on hawthorn berries in a hedge on the far side of the river, and two Herons, one of which flew up and perched on the roof of J&K Aquatics warehouse ........ Somewhat optimistic, I thought !!!!!
