Orientarium - Jungle Hall - Sun Bear (Helarctos malayanus malayanus) and/or Javan Lutung (Trachipithecus auratus)

Is this a mixed enclosure or do the two species rotate? I’ve heard of sun bears with binturong but never with primates.

Good question. This enclosure doesn't seem appropriate to mix both species, so I guess the bears are behind the scenes and can only be seen outside. But several months before my visit, someone saw bears in this enclosure and no primates.
On a side note: I saw in Lodz 3 different groups of Javan lutung, totalling 8 animals.
