Abstract Using the line transect methods, I studied the primate density at Ngogo, Kibale National Park, Uganda for 18 months. Comparisons with other studies show that the population of red colobus monkeys ( Procolobus rufomitratus ) and blue monkeys ( Cercopithecus mitis ) is declining, whereas the populations of black‐and‐white colobus ( Colobus guereza ), red‐tailed monkeys ( Cercopithecus ascanius ), grey‐cheeked mangabeys ( Lophocebus albigena ), baboons ( Papio anubis ), and chimpanzees ( Pan troglodytes ) remain constant or slightly increase. In this paper, I compare data on density from this study to data from previous and recent censuses at Ngogo and with data from other sites in the Kibale forest to examine the stability of primate populations. Furthermore, I test the hypothesis that the changes in red colobus and blue monkey density are due to changes in the forest structure and abundance of their most selected feeding trees, and show that changes in forest composition cannot account for changes in their red colobus abundance, but that hunting by chimpanzees provides a reasonable explanation.
