This looks like a decent size exhibit for loris - certainly the biggest I have seen. Any idea of how many where in there? I presume they are a local species, so perhaps Kayan River slow loris (Nycticebus kayan)?
Only one individual. The exhibit's good in terms of size and vegetation (which this photo doesn't do justice). My concern was negative visitor effects, although they're possibly ameliorated by Green Connection's lack of visitors! More climbing opportunities would also be a bonus.
As for species, I'd say Bornean (Nycticebus borneanus). I didn't see the face, but its back had red fur which I don't *think* you get in the brownish Kayan River lorises. However, my Payne & Francis field-guide was published before the split, so someone else may know otherwise.
