Short Communication


Among New World monkeys, spontaneous tool use and object manipulation are commonly descirbed inCebus species only. We report here an occurrence of tool manipulation by a wild male red howler monkey (Alouatta seniculus), observed using a stick to softly but repeatedly hit a two toed sloth (Choloepus didactylus) resting in the same tree. The ecological context of this unusual behavior for this quiet species generally showing very little manipulative propensity is discussed.
