This does appear to be a great wolf enclosure, and it got me thinking about the many truly excellent wolf exhibits that can be found in most modern zoos. From Vancouver to Chicago, Oklahoma to Columbus, Cincinnati to Seattle, etc, there are countless fantastic wolf exhibits scattered across North America that are often an acre or two in size. There are also loads of great wolf enclosures all across Europe, so perhaps that is one species that is normally well maintained in zoos?
The only sad thing is they are not allowed to breed anymore as the zoo had problems to find enough takers for the last litters. So the group now consists the original pair and 4.0 of their puppies (2+2 from the last two litters) now grown up. Yet observaing the hierarchy related dynamics and ocassional chase of birds is breathtaking (it helps that the alpha male has significantly darker pelt - not so common among euroasian wolves - so he is easily distinguishable from others). The exhibit has three viewing platfroms from very different angles yet there is enough privacy for them and one quite out of sight corner. It all looks very natural and I like this exhibit a lot.
