A survey of primates in central Pará

Abstract

The distribution of primates between the lower Tocantins and Xingu Rivers in central Pará was surveyed. In addition to the seven species known to exist in this area, the occurrence of Callithrix argentata was confirmed. Sympatry between C. argentata and Saguinus roidas niger was also recorded, although mixed-species associations were not observed. The results of the study indicate that the distribution of C. argentata may be restricted to the relatively fiat lowland forest in the north of the region.
