Just Box 3 remaining

The single bird in Box 1 now seems to have left as it’s no longer roosting at night but we still have our pair in Box 3. Yesterday we saw another pair of swifts doing flypasts, obviously having a look at all the boxes and one landed on the entrance to Box 4 but neither entered and they went away again shortly afterwards. Our pair in Box 3 are still flying about with a third bird so whether or not this is the one from Box 1 still hanging about we don’t know. Here are the pair in Box 3, still looking happy enough!
