I spent an hour or so on Christchurch Park, Ipswich this morning, probably caught the trees at their best, see the YouTube film clip here, sorry about the camera shake, that is the way it is these days:
The first part of this video is on the park 100 yards from where I live taken yesterday, the wooded area is a little further at 400 yards today, so when I say I am off for a walk you know where I am off to, there is no sound apart from a few birds chortling away in the wooded section
