Volunteer – Be the Scientist

Witness the dramatic social lives of toque macaques and langurs. With a little training from us, participants learn the methods to record monkey behavior, to analyze data, and to interpret their observations. Choose between current projects (tests of hypotheses) to participate in. There are daily data summary sessions and discussion among staff and visitors. Lectures or documentary films are offered in the evenings. Participants would stay with us for two weeks at our Field Research Center.

What you’ll experience

You’ll see up close, three primate species: toque macaques, hanuman langurs, and purple-faced langurs.

You’ll be amazed by the monkeys’ rich repertoire of facial gestures, calls, and postures that they use to communicate with each other. Monkeys also exhibit a great variety of social behaviors, including: maternal care, courtship, social networking, play, turf wars, food competition, grooming, anti-predator behavior and possibly infanticide, among others. And your appreciation and does not end there – because each primate species has its own language.

You’ll be assisted by our expert field staff to identify, record and understand the monkeys’ “language” and social dynamics.


  • You’ll contribute new data for testing current behavioral or ecological hypotheses.  Your observations also may help to resolve some conservation challenges. Monkeys are forever having social or environmental issues.  Depending on ongoing events at the time of your visit with us, you may have an opportunity to engage in a project focusing on an unusual monkey affair. You may also contribute through your special abilities in photography,  IT, or other skills.
