Yes, it is, and teh wolverine can climb high up the trees. Theer is a sparrow at the fence which shows the visitors the favourite sleeping place of the female where they can see her most of the time, 10 meters up in a tree....
I'm so Sorry for the mistake, yes,I've meant of course Arrow and not Sparrow. I guess, the wolverines would have their fun with a sparrow at the fence of their enclosure...Unfortuntaley, there are to similar words in the english language....But it is nice idea with a trained sparrow, isn't it ?
