Now that the orangutan FOREST has been completed and there are a few photos in the ZooChat gallery I think that it is safe to say that the exhibit has become a joke. Colchester Zoo does have a few very nice habitats, but the completed orangutan enclosure is hideous.
From what I've seen in the pictures, I agree. It's almost as if ,as with Gorilla kingdom, they just thought about the outdoor area afterwards and literally just walled in a pretty small area with a second rate climbing frame.
