The first program is the PROYECTO TITÍ. Designed to preserve the Cotton Top Tamarin. From their website, "Proyecto Tití is a multi-disciplinary in situ conservation program that combines field research, education initiatives and community programs to make the conservation of natural resources economically feasible for local communities in Colombia. The program is designed to provide useful information to assist in the long-term preservation of the cotton-top tamarin and to develop local community advocates to promote conservation efforts in Colombia." I really love their focus on the community. They are helping prevent deforestation by giving people other options for earning money. Learn more at their website:
The second program is the FUNDACIÓN BIODIVERSA COLOMBIA. Amongst the many programs they are working on is a program designed to save the Tití Gris. It has a long list of Zoo sponsors, and you might be able to find out more from a local Zoo listed on its site. Unfortunately, most of the information is in Spanish.
