Taken 12/9/16. This complex, subtitled "People of the Forest", of 2 adjoining exhibits for Bornean orangutan opened in 2011 and includes both indoor and outdoor viewing areas of both exhibits' indoor and outdoor spaces.
This exhibit has also had some climbing apparatus added. I was actually contacted by a representative of the Phoenix Zoo after I was rather critical of this new exhibit when I visited and then reviewed the zoo online in 2011. One of the orangutan outdoor habitats is quite well furnished with climbing frames, but on my visit in 2011 there wasn't much of anything in the indoor room or the second outdoor habitat. I'm glad to see a huge improvement!
