I would say they aren't very common, but this may be a biased view as I haven't visited all of European zoos… I guess they'd be a bit more common in collections located in the proximity of their natural habitat. This means they'd be more common in Austrian, Swiss, German and to a lesser extent French and Romanian collections. Mind this is my personal observation, and so I may be wrong.. I remember seeing them only in one North American collection, namely the Toronto Zoo. Taken the small group they keep, it seemed as if the zoo were waiting for them to die out...
Zootierliste shows htem in 45 collections, the majority (36) in Germany, Austria and Switzerland, and the rest in surrounding countries in central Europe. They appear to be mostly found in smaller collections (wildparks, which I think mostly hold European species), although a few big zoos hold them too. Are there any left in North America? They are actually an introduced species in New Zealand, but I don't think there are any in captivity there.
Well, I remember seeing them at the Toronto Zoo. The herd seemed very small, and I got the feeling the zoo's waiting for them 'to die out'… I may be wrong of course. I've never seen them in American zoos though.
