So, the swifts have nearly gone until next year. I heard some screaming this morning and saw one this evening, but already they are moving south to warmer climes.
Most swifts have gone by mid-August although swallows are often seen much later.
With swifts you just realise they are no longer here. Sad, but they will be back. To me, the screaming swifts are a mark of an English summer.
