Here is another photo of Colton in the Wild Side.  Curator Coy reports that he is showing some appropriate wild behavior, such as climbing up a tree when he senses the presence of a human.  Remember, because the fences are covered with blinds, he can not see a curator approach, but he can hear him and smell the human scent.  In this photo, it looks like he is calling for more food.

This photo shows how Coy throws the food over the fence, so Colton has to forage for it.
