Primates and Predator Interactions

[brotherbear]

I know that it is possible for a leopard to ambush and kill a bull gorilla. But do they? There was a post a few years back on the old AVA site relating a news article of a leopard feeding upon the carcass of a silverback. However, the actual killing was not witnessed and no specifics were given such as the age or physical condition of the gorilla prior to his death. I would think that if leopards posed a real threat to bull gorillas, after a few million years these great apes would have started spending less time on the ground.
I believe that the tiger is the number #1 reason why the apes of Asia are all arboreal. I did read ( somewhere ) that sun bears sometimes clash with orangutans over jungle fruit. That might be interesting to observe.
I will edit and add - I watched a documentary a few years ago about leopards which included various leopard populations in both Africa and Asia. It stated that the one animal of the Congo that the leopard fears is the chimpanzee. Reply
