We have swifts at last! On the evening of 10th May, two birds returned to boxes 2 and 3. We hadn't touched the nesting materials, just left the boxes as they were at the end of last year so that the swifts could sort out their own bedding. They've been in and out this morning and look settled, we're hoping we'll get some takers for the other 4 boxes shortly. So it looks like we are in business again after a long winter wait!
