I was out at work in the Lakes yesterday when I spotted this little mite running backwards and forwards. As it went from left to right it had a mouse in its mouth, and on the return journey it was empty. By the looks of it there was many a happy hunting trip.
Looking back I think it was a weasel, slightly smaller than a stoat but still has a white underbelly. A stoat sometimes has a black tip on it's tail which this little un didn't. It's a busy time of year right now for all of our nature with lots of hungry mouths to feed.
