Delighted to report that my much-talked-of owl box does actually seem to be occupied by a breeding pair of barn owls. I recently wrote about having captured a single photograph of an owl visiting the box, and wondered whether the lack of any other evidence could be down to a faulty camera sensor. To settle the matter, I returned again with the camera on its finest possible setting last night and managed to get over a dozen photographs of owls coming to and from the box between 10:30pm and 3:20am. This is a seriously good sign, and I am thrilled to think that there is genuine value in something I built with my own clumsy hands.
More owl boxes (and perhaps a better camera) are on the way.
