Perhaps, I thought bird of prey only because they tend to tear at the meat rather than chew it like I would expect Mr fox to. We have barn owls, buzzards, and foxes in the field and I saw a smaller hovering brownish bird hunting there last weekend, I thought maybe a kite as it had a blunt/square tail but it wasn't close enough to see much detail. There is also an otter family in the river at the other end of the field. Don't know which, if any of those might pull them inside out though.Hmm, yes could be an owl? Or would it be more mashed up (cos they regurgitate?) We often see similar. I sometimes suspect rats. Is it quite fresh looking? Because they do assume that look when they've been there a while. (Hard to tell from a pic of course).
Kites (Red ones) are slightly bigger than Buzzards, have a forked tail and are beautifully coloured if you see them close enough up. Kestrel is the only true hovering BOP although others do use the wind against their wings to maintain a stationary position. Good point about the Otters, we definitely don't have those in the back garden but we do see the occasional Stoat. Don't know if they prey on birds? I wonder if a Sparrowhawk had been plucking it and somehow turned it inside out ... maybe a young one that hadn't got the hang of it yet, although I'd say turning it inside out to get at all the inside bits is a good move if you can't cut it open to reach them. What could be strong enough to kill something but not able to tear its skin open and yet clever and dexterous enough to turn it inside out? Am I over thinking this? Do love a good mystery.Perhaps, I thought bird of prey only because they tend to tear at the meat rather than chew it like I would expect Mr fox to.

That's our first real lead, I think I'll have to set up the wildlife camera to see if I can catch evidence of the little critters being aroundI've heard that stoats turn prey inside out. Weasels might as well, they are ferocious little things!
