Rosamira Guillen











Guillen started her professional career leading the process of remodeling the Barranquilla Zoo and later becoming the Zoo’s Executive Director, through which she acquired experience in the leading and management of a non-profit organization that raised funds for the conservation of Colombia’s native wildlife.

Protecting the cotton-top tamarin

During her work at the Barranquilla Zoo she learned about Proyecto Tití, a conservation initiative to protect cotton-top tamarins (Saguinus oedipus) founded by Anne Savage, Ph.D., which called her interest towards this unique primate species. The cotton-top tamarin is only found in northern Colombia and is critically endangered. The work of Proyecto Tití motivated her to volunteer as the co-founder and Executive Director of Fundación Proyecto Tití, to lead the efforts to protect cotton-top tamarins and their forest home. In 2008, she became the full time Director of Fundación Proyecto Tití and since then, dedicated her work to advance the conservation efforts of this organization.


When I learned about Proyecto Tití, I became fascinated by the unique cotton-top tamarins. Since then, we have protected more  than 13,500 acres of forest in Colombia to protect the species.

Under her leadership, Proyecto Tití has accomplished, among others, the classification of cotton-top tamarins as a critically endangered species in Colombia, the terminiation of the building of an international airport that threatened the conservation of one of the most important forest remnants for cotton-tops, the protection of more than 13,500 acres of forest areas in northern Colombia through different strategies, the design of a National Program for the conservation of this endemic primate, and the strengthening and expansion of Proyecto Tití’s community and education programs to reduce human pressure on the conservation of the forests that are home to cotton-top tamarins.

Awarded conservationist

Her work has been recognized with important awards in Colombia, such as the CARACOL Award to Environmental Conservation in 2014, and internationally, such as the Whitley Award in 2015, the National Geographic / Buffet Award in 2017, and the Latin-American Green Award in 2019.
