We had heard that they use stones or branches that they carry with them to crack nuts. We are thrilled when we spot a chimp sitting on the forest floor about 20 feet [5 m] from us, banging away at a nutshell with a branch.
Mēs esam dzirdējuši, ka šimpanzes mēdzot nēsāt līdzi zarus vai akmeņus, ar kuriem sist riekstus, tāpēc esam īpaši sajūsmināti, kad ieraugām kādu šimpanzi, kas sēž zemē aptuveni piecus metrus no mums un dauza riekstu ar zaru.
