Chimpanzess hunt in an organized manner; orangs are not meat eaters.

Ape culture hints at earlier evolution

The complex behaviour of orangutans suggests human culture started to develop 14 million years ago, much earlier than thought. At this time the ancestors of chimps and orangutans diverged...

New ape population found

Conservationists believe about 2,000 rare apes are living out of sight in a remote lowland region of East Kalimantan. The find, if confirmed, will raise the number of known orang-utans in the world by about 10 per cent... The claim, by researchers from the US-based conservation group Nature Conservancy, is based on signs of nests made by the apes... They are in grave danger of extinction, because their habitat is under threat from illegal logging, forest fires and gold mining... Primate experts have predicted that the apes will be found only in zoos by the year 2020 unless immediate steps are taken to protect them.

Orangutans? I think not. The adult males are solitary. The females are a bit more gregarious. And no orangutan does much "hunting." They forage, and they're not comfortable on the ground.
