• pumpkin-size Treculia africana to rubbery, so ball-size Chrysophyllum lacourtiana---that makes the Goualougo such an attractive habi- tat for chimps. Our destination this morning is the primary range of the Moto community, one of 14 distinct chimp groups that call the Goualougo Triangle home. Periodically the sound of a distant pant- hoot pierces the forest. When that happens, Morgan sets the bearings on his compass and we tear off on a sprint through prickly brambles and knobby lianas. Mangoussou, a Babenzélé Pygmy who stands barely ve feet tall and has a mouthful of teeth chiseled to sharp points, leads the way, sometimes slowing to clip a path through the understory with a pair of gardening shears. A er one ve-minute dash, we spot a half dozen chimps lounging in an Entandrophragma tree about 130 feet o the ground. We watch through binoculars as a puckish subadult female, a new immigrant to the Moto community, horses around with Owen, a juve- nile orphan whose mother was recently killed by a leopard. With a small twig clenched be- tween her teeth, the female (Morgan and Sanz later generously named her Dinah, after my wife) chases a er Owen and wrestles him onto a Primatologists Dave Morgan and Crickette Sanz examine tools their subjects use to secure food. Chimps agitate underground safari ant nests with long saplings like these, then use stems to collect insects forced to the surface.
