Tetters asked me to get rid of an old chair so I sawed the legs off and turned it into a owl box Found a suitable tree with some forked branches and with a bit of sawing and cussing I hoiked it up there... It didn't move but just to be on the safe side I secured it with some cable ties. There are a few owls about, we here them at night and one flew over my head the other night while I was out looking at the moons of Jupiter. Have you got any bird boxes?
