The swifts have gone.

We returned from our holiday yesterday and at a BBQ today with Gary he pointed out that the swifts left here a couple of days ago. When We went to Norfolk a week and a half ago there were still groups of swifts still swooping low over the house with their distinctive squeals but sure enough they do seem to be gone. Gary says they arrive each year in the first few days of May and leave on about the 2nd of August. They also seem to have been replaced by wasps.
