Three marmosets with hammocks and toys viewed on the Callicam

The Wisconsin National Primate Research Center supports one of the largest colonies of common marmosets (Callithrix jacchus) in the United States. Through the Callicam, anyone with web access can observe one of the WNPRC’s common marmoset families. The Callicam webcam allows site visitors to pan, zoom, and manipulate the camera themselves for two minutes at a time. Accompanying links to comprehensive information about the species along with sample exercises for use with the Callicam (see below) provide the opportunity to learn about this engaging primate while observing it live online.

Open the Callicam

The family you see live on the Callicam includes two adults and two of their grown offspring. Adult males have blue neck tags and adult females have red neck tags. Mom and Dad are no longer breeding; however you can watch our video that includes a previous family with infants growing up here. Marmosets can live to about 18 years in captivity and 12 in the wild.

Dad “Link” was born 11 April 2011

Mom “Rose” was born 23 May 2011

Grown offspring:

Male “Felix” born 1 Sept 2015

Male “Jon Snow” born 24 Mar 2018

If you do not see any animals, the marmosets are either temporarily out while the vivarium is being cleaned (usually alternate Tuesday mornings), or the lights are switched off so the monkeys can sleep (usually from 6 pm to 6 am). They might also be resting or sleeping in hammocks and out of view.
