This photo shows perhaps 25% of the entire outdoor area for the 5 orangutans at the Woodland Park Zoo, and there are 3 apes in one enclosure and 2 in another that is cleverly separated via a hidden moat.
This one does look good - quick question though - are there any indoor, on-show areas? Seattle's not a place I would associate with year-round sunny weather!
@Maguari: I'm turning ZooChat into an orangutan Sunday event! There are well-furnished indoor areas that are in full view for the public, and often in wet weather the apes will hang out inside.
