Lovley set Geoff. I'm going with the first as the wild one even though it's in the middle of the shoot. One simply wants to get a photo like that in the wild.
There don't seem to be any rules about how many guesses are allowed, so I am going to take another guess. I notice that all the photos seem to have the same terrain, snow with brown grass, except the fox which is a rocky slope with some weeds. Further, it is hard to get a good photo of a wild fox, so most close fox photos are captive fox. I suspect arbitrage is trying to throw us off! The only reservation I have is that the fox may have an injured right rear leg, which is the type of condition that lands many animals in wildlife reserves. Regardless, my second guess is the fox, #5.
BTW, is there any prize for getting the right answer?

P.S. On further examination, that's probably a coyote.
Very nice variety. I'm guessing all of the animals in the dry grass habitat are in a preserve. If the two arctic foxes are the same animal, this leaves the red fox as the only candidate for being in the wild, damaged leg and all.
