We’ve rescued the owl box that came down with the old oak and have put it up in place of the old owl box on a huge old (living) oak nearby.
No time to get the cameras inside it working yet but a trailcam by the tree has captured a barn owl already settling in to the new residence. It’s ringed and may well be one of the pair that were using the same box before. Not sure what it makes of the enforced move but it seems happy enough.
