Gorillas Throwing Sticks

Interesting point regarding the Cross River gorillas, and their behavior towards humans:

"In the wake of a study that documented for the first time the use of weaponry by Cross River gorillas to ward off threats by humans, the Wildlife Conservation Society announced today new field surveys to better protect this most endangered great ape.
"The study, published earlier this year in the Journal of Primatology, found several instances of gorillas throwing sticks and clumps of grass when threatened by people. Gorillas usually flee and rarely charge when encountered by humans.
"Cross River gorillas are restricted to Nigeria and Cameroon. They number only around 300 individuals, making them the most endangered of the four gorilla sub-species." (Eurekalert)
