I am looking for detailed informations about what chimpanzees eat when living wildly in nature and would be glad for any indications.

Chimpanzees eats fruits,seeds,leaves,bark,insects,& honey. Chimps are also ominivorous mean occasionally they eat meat like young monkys, bush pig, etc...
Hope I helped. :D

Thanks for the answer.
But I really need quantified information:
- how many different fruits, vegetables etc.
- how much weight of each

This might be helpful:
