I wondered what might have done the damage shown in the photograph. The chunk of wood is one of several waiting near the bank of a stream at the bottom of our garden to be chopped up for firewood. We live in north Herefordshire so any suggestion that we have beavers in the stream seems unlikely. The neighbours have cats but I've never seen them do this much while scraping their claws. Any ideas? Please?
Notice the shredded pieces of wood have not been flung very far - as might happen if a fox was letting rip, for instance. I suspect a more methodical creature such as badger, or a smaller creature such as a woodpecker (or maybe jay). In that soft wood, you wouldn't have heard it chipping away. Rotting tree stumps can contain quite a few larvae of beeltes, moths and other invertebrates.
