@ Sun Wukong … Thanks for the info about mixed exhibits with manatees. By the way I have not knowledge of that West African manatees are kept in captivity, I thought such the Caribbean manatee live in zoos currently.
About elephants & hyraxes (and the theme connecting with this): I didn’t say that zoos should turn back to display their animals by taxonomy aspects like in many zoos’old days. The elephants & hyrax combination is just an example. What you were mentioned beforehand, for example the Pachyderm House at Tierpark Berlin Friedrichsfelde, is not the same thing we talked about. This theme is collection planning and exhibit concept, but not mixed exhibits. Taxonomyc aspects would be interesting in some cases in mixed-exhibits, so I would not go back the inappropriate display technics. And yes, taxonomy for visitors are not very interesting, but this combination just one example I mentioned. I just emphasize that mixed exhibits should keep species together which not just come from a same habitat (yes, this is the main requirements), but in addition any other connection (like similiraty in any factor, in behaviour, symbiotic connections, etc…) These would be much the same habitat displays that you said is good, but a bit more I think …
@ Chris ….Some mixed-exhibits with bear species (I try to write about what had not been mentioned in this thread earlier):
Brown bear & Nothern lynx at Salzburg Zoo
Brown bear & Wolwerine at Tierpark Dählhölzli, Bern
Brown bear & Red fox at Skansen Foundation, Stockholm, at Zoo Ljubljana, and at Dartmoor Zoological Park
Brown bear & Arctic fox at Veszprem Zoo (not exist already)
Polar bear & Arctic fox at Zoo am Meer, Bremerhaven (earlier at Dublin Zoo and Omaha’s Henry Doorly Zoo)
North American black bear & Grey wolf at Woburn Safari Park and Ree Park – Ebeltoft Safari
North American black bear & American bison at Safari Parc Peaugres
Asiatic black bears & Hanuman Langur at Zoo Ostrava (this just a plan, not exist currently)
Sloth bear & Hanuman langur at London Zoo (earlier with Lar gibbon and Muntjac) … but I don’ t know exactly this mixing is work now or not …
Sloth bear & Barbary macaque at Safaripark Beekse Bergen, Hilvarenbeek … this exhibit not exist already, because sloth bears killed one macaque in front of the visitors …
Sun bear & Binturong at Parc Zoologique de St.-Martin-la-Plaine
The Sloth bear & Rhesus macaque combination in Leipzig work well, but they have some problems with environmental enrichment, because macaques are more agile than bears. The Spectacled bear & Coati combination are also tried in Zoo Antwerp and Los Angeles Zoo, not just in Zürich.
I put up an interesting link about mixed exhibits (I don’t know you know about this or not). It includes photos about some accidents connecting with mixing, and some example what there were mentioned here beforehand. Here you can see it:
