Survey of De Brazza's monkey (Cercopithecus neglectus Schlegel) in the Tororo district of Eastern Uganda and Trans-Nzoia and West Pokot districts of Western Kenya
Censuses of De Brazza's monkey Cercopithecus neglectus were conducted in the Tororo District of eastern Uganda and in Trans-Nzoia and West Pokot Districts of Western Kenya to determine the status of this species and its habitat. The species had not been reported in eastern Uganda since 1958, and a previous census in Western Kenya had reported it under threat. In Uganda 13 sites were surveyed, and 124 individuals were counted in 20 groups ranging in size from two to 22 individuals (x=5.8). In the 11 sites surveyed in Kenya, only 68 individuals were counted in 19 groups ranging in size from two to six individuals (x=3.56). In all these districts, De Brazza's monkeys are threatened with local extinction due to pressures from deforestation and hunting.
