@Jurek:
"I hope you understand that general high standard of Berlin Tierpark and financial wealth of the city makes high expectations. What may pass in a small provincial zoo in Eastern Europe* is not acceptable in Berlin. Tierpark resembles a man who wears Armani suit, drives a BMW but has dirty socks full of holes.
*just kidding, many East European zoos have buildings and breeding groups on the level of the best German zoos. Think ungulates at Dvur Kralove, rainforest hall at Zlin, pyramid at Sosto, or some projects at Prague."
In fact Berlin as a city isn't doing that well economically. Some 60 BIO debts and an average income per capita close to the rest of Europe (nothing like Frankfurt, Munich or Hamburg). Soon they aren't allowed any new debts and the funding for the Tierpark will be further reduced (as it has been for years anyways). The new master plan also was first forced upon the tierpark and after they presented it the city government immediately stated they won't pay for it...
So if it was only dirty socks with holes I would be glad (hardly anyone would notice them unless they smell too bad

) but I think Armani suits and BMW rather apply to some other zoos that easily invest dozens of millions for new projects that are usually both well suited for the animals AND quite impressive/ entertaining for the visitors (in some cases with more emphasis on the latter). In my eyes the tierpark rather resembles a guy with somewhat worn out jeans and an old but still running Volkswagen - not necessarily with overly dirty socks or underwear, though (it's still doing the job very well, but it's not gonna win any beauty contest).
@Pertinax: I linked the entire new thread on animal husbandry starting with a post that contains many pictures (just try it, I did not program any virus

). If you scroll down a bit until you get to
primates and then
monkey house you will find some pictures of the outside boxes. I'm not sure if the one you mean is on there, but I took all I deemed representative so it might well be.
