I could watch Chimpanzees for hours. They are so close to us humans it is sometimes quite scary. At Chester Zoo they have a very large indoor and outdoor play area with climbing frames and ropes. You see the younger ones inside a lot, but in the half dozen times I have been I don't recall every seeing them outside on the ropes. It seems they always sit or lie just at the doorway here in a group, just as you can see above.
