Parasitic health of olive baboons in Bwindi Impenetrable National Park, Uganda.

This study examined the endoparasite load of a group of olive baboons (Papio cynocephalus anubis) that share their habitat with a population of mountain gorillas (Gorilla gorilla berengei) in Bwindi Impenetrable National Park, Uganda. During a 2-week period in June 2002, shared habitat was substantiated by noting the ranging patterns of both species and recording observations and trail remains with a global positioning system (GPS). Parasite load was determined by collecting fecal samples preserved in 10% formalin and analyzed by sedimentation techniques and immunofluorescent antibodies (IFA).

Chimpanzees in Bwindi-Impenetrable National Park, Uganda, use different tools to obtain different types of honey.

Evidence of tool use for foraging for honey by chimpanzees in Bwindi-Impenetrable National Park, Uganda, is reported. These are the first records of tool use by chimpanzees in this region of the Albertine Rift. Tools of two types were found at sites of bee activity.
