Yesterday morning we woke up to find a pair in box 1 and a single swift in box 2.
Then last night three swifts roosted, in boxes 1, 2 and 3, each on their own, so either the partners are still out there somewhere, or at least one of them is in the wrong box…. Good to see that my newly reduced sized entrance hole (65mm x 28mm) on the new box 2 (and new box 4) is still manageable for swifts but hopefully not for starlings.
