Project Overview

Primates Peru is an as yet unincorporated nonprofit organisation based on the dissertation field research of Mrinalini Watsa, as affiliated with Washington University in Saint Louis. The project focuses on a previously unstudied population of saddle-back tamarins (Saguinus fuscicollis) in south-east Peru, at a state-of-the-art biological field station (CICRA) on the Río Madre de Díos.

The goals of the project are two-fold:
1. The acquisition of suitable genetic material from subgroups within the tamarin population.
2. Observation of behavior in the context of reproduction, infant care and alloparenting.

Species information

The saddle-back tamarin (Saguinus fuscicollis) is the smallest but most widely distributed tamarin¹. It is found all the way from the mouth of the Amazon in the East to the slopes of the Andes in the West. Other callitrichid genera it is sympatric with are Goeldi's monkeys (Callimico) and marmosets (Mico).
