Members of competing species may influence their share of food sources either by finding new feeding sites more frequently or by more effectively monopolizing those sites once found. We describe a model that separates the effects of these two forms of competition; in a set of African forest primates, only the first has a major effect on species' relative population densities. The model identifies factors which might lead to a greater role of interference at food sources in other communities.
