Otter, Orca, Sea Eagle, Basking Shark.
All perfectly feasible in the UK, these days. I never thought I’d see Red Kites in the wild, now they’re all over the place, even saw one flying over the centre of Chippenham one Saturday afternoon. Same with Ravens, too.
Seen a mole scuttling along the kerb on a main road, once, turned around to go and rescue the daft little bugger, but he’d vanished by the time I got there.
It’s really not at all unusual to see badgers running around in the road around where I live.
Or deer, for that matter; been lucky not to hit one, they suddenly shoot out of field entrances, or even jump over the lower hedges, not what you want landing on your bonnet… 🙁
