At last, and not too late for breeding this year, a pair of barn owls have appeared. They arrived last night with a lot of fussing and mutual preening on the ledge of the old nest box. The female has settled in to the box for the day and the male is probably roosting somewhere nearby. Fingers crossed for hootlets this year.
We need to evict a squirrel from the other nest box to allow the owls to use it as a roost for when the old nest box gets too crowded (we hope).
