The Wolverine (Gulo gulo) is the largest land-dwelling species of the Mustelidae or weasel family (the Giant Otter is largest overall) It is a mammal slightly bigger than the Badger. The shy wolverines prey at night in the dusk, and it is very rare to observe one in the wilderness.
The Wolverine, however, visits the hides all year round and from early spring until autumn there is enough light to see it properly and take decent photographs of it. With a bit of luck it can be seen even in the daytime.
