Another beautiful Spring day and thinking ahead I wanted to spend some time making and putting up nest boxes in time for swifts and house martins. With the prospect of returning breeding swifts I need to have all the boxes in place now to avoid disturbing them when they return. Several years ago I had a swift return to one of my nest boxes on 16th April. This was exceptionally early for a returning breeding swift and it then had to wait another 14 days before the next swift arrived back at the colony!
Making nest boxes is an activity full of hope and anticipation. Today, I fitted a camera in a nest box which was visited by a non breeding swift last Summer. So all is now ready for the returning birds. The weather was so warm today I was almost expecting to see house martins and swifts above. For now, all the boxes have the entrances blocked to stop take over by tree sparrows. There are plenty of nest boxes provided elsewhere for sparrows though they nearly always attempt to move to the swift boxes for their second broods.
