At 22.45 last night box 2 just had the two swiftlets in it. There were also single swifts in box 3 and box 5, see below.
At 22.50 the two adult birds returned to box 2 and the single swift in box 5 left, leaving just boxes 2 and 3 roosting. By 7.10 this morning, boxes 3, 4 and 5 all had single swifts in them briefly, along with the family in box 2. We think that the pair that were roosting in box 1 for over a week have probably now left to join the exodus leaving from Spurn, so hopefully we shall see them back here again next year.
