Lovely start to the day but just after lunch the heavens opened with heavy rain for nearly 3 hours. All 3 swifts returned to the nest until the rain stopped then they all went out again returning 6pm ish. Clip of the 2 from the chimney nest about to fly off after the rain. Second clip is of the single swift in bedroom nest continuing to set up the nest. He has been waiting a long time for its mate. Starting to get concerned but do realise many swifts are still returning.
