So it seems despite being a particularly 'special' owl, often showing little evidence of intelligence, the long eared little lad turned up this morning tired and very squeeky. Poor thing. He made it back though. This is wonderful news as I think a few of our regular customers and the staff's hearts would have broken if he'd been lost.
Moral of the story: plenty of walks around the surrounding area of home can be great for unforseeable moments in a bird's life where flight of fancy (literally) can leave them wanting for a map.
