Interesting day. This morning there were 4 swifts screaming round the house with 2 on my two occupied nests. Another was flying at the same time. Will have to check there isn’t another nest that I don’t know about. No signs of the single swift in the attic nest today. Two clips first showing both swifts in the bedroom nest with the 3 eggs. The second a close up of one of the chimney nest swifts.
