Took Rosie the reluctant cocker spaniel for another drag around Crow Nest Wood. As we entered the beech trees, I heard what I took to be rain starting to fall through the leaves. But then I realised the sound was coming from a single tree. As I looked up, trying to work out what was causing the noise, about 20 wood pigeons exploded out of the canopy and headed off across the valley. I guess they must have been foraging for beech mast, in the process dislodging leaves and seed husks which pattered down through the lower branches like rain.
