Andrew Baker (Philadelphia Zoological Garden), Alcides Pissinatti (Centro de Primatologia do Rio de Janeiro), and Andria Davis (Philadelphia Zoological Garden) have produced the 2004 studbook for the pied tamarin, Saguinus bicolor, with data current through 31 December 2004. It includes a full historical listing as well as a separate listing by institution. The text is in Portuguese and English.

At the beginning there is a brief discussion of taxonomy and a description of the species and subspecies (bicolor, martinsi and ochraceus; the studbook concerns only the nominate subspecies) along with their distributions, habitats, diet, reproductive parameters, social structure, behavior, and status in the wild — all you ever wished to know about pied tamarins and more: an excellent summary.

The current captive population of Saguinus b. bicolor is derived largely from two colonies, both established in the 1980s: one at the Centro de Primatologia do Rio de Janeiro (CPRJ) and the other at Universität Bielefeld (Germany). In 1996, CPRJ acquired additional wild-caught founders, a step forward in expanding the founder base. A number of these new founders were sent to European institutions. As of early 1997, all of the animals outside of Brazil are under the ownership of the Brazilian government, through the Brazilian Institute for the Environment and Renewable Natural Resources (Instituto Brasileiro do Meio Ambiente e Recursos Naturais Renováveis – IBAMA). On 31 December 2004, the number of living animals in the breeding program was 117 (50.51.16) in 19 institutions, including 11 founders with living descendants. There were 33 births during 2004 and 28 deaths. The population as such has grown considerably since the mid-1980s, and the age pyramid shows a healthy number of young animals between 2–7 years old.
