Apology accepted, it surprised me that my comments seemed to stir such strong emotions. I do agree however, that no matter what kind of enclosure an animal is kept in, interpretation is always the key to a good visitor experience (I'm referring to visitors who aren't zoo nerds now). Distance is a problem for some people, sure. A good zoo will use enrichment to overcome this.
I have also seen capuchins in enclosures similar to this acting natural, but I have also seen stereotypical behavior in quite a few animals, as well as animals who were obviously not used to climbing on anything that moved, and who moved like very old animals, despite them being in different ages. Like I said in my first post, these animals might be well off if they are given good enrichment regularly, but I (and I'm not demanding everyone should agree) still prefer seeing them in larger, more complex environments with access to living trees.
An important point IMO is the location of the enclosure. While this is a cage, it is set within woodland. I believe canopy-dwelling primates benefit from these surroundings rather than one or two trees in a hotwired paddock. Invertebrates in the wooded area won't avoid the cage just because it isn't a natural tree, moreso as the structure matures, the only thing I would have liked to have seen is a little more height, but its clearly adequate for a small group and Shaldron excel at enrichment.
