Swifts still here this morning

I thought all the swifts would be gone by the time we got back from holiday. But no, at 7 this morning they were still circling above our garden, in large and small groups, screaming and swooping around in the sunshine.  Sometimes a wing would flash silvery-white as the sun caught it. So this presented me with one more opportunity to get out there and try for a sharp photo. This one is heavily cropped, there as a nice summer memory really.
