GLT Story finalist for 2016 Excellence in Science Books

Attention zoo educators, teachers, parents, and anyone wanting to promote young people’s science-based actions in conserving the diversity of life on our planet! Susan Markle’s The Great Monkey Rescue: Saving the Golden Lion Tamarins was named a finalist in the Science Books and Films 2016 Prizes for Excellence in Science Books.  Sponsored by Suburu and AAAS (the publisher of the prestigious journal Science), the annual competition highlights books that promote science literacy among children and young adults – helping kids to identify the right questions and the best ways to answer them. Markle’s book is based on extensive interviews with Associação Mico-Leão-Dourado and Save the Golden Lion Tamarin, who also provided many of the photos in this gorgeously illustrated book.


The book can be purchased at – make sure to choose SGLT as your charity to benefit from your Amazon Smile account!


The Great Monkey Rescue

Saving the Golden Lion Tamarins

The Great Monkey Rescue is a soberly written yet inspiring guide through the near demise and science-assisted rebound of a squirrel-sized primate known as the golden lion tamarin. The easy-to-digest text is packed with interesting facts and set against vibrant pictures of bright orange monkeys and lush green foliage. Golden lion tamarins live exclusively in Brazil’s Atlantic Forest, an ecosystem that has shrunk to less than 10% of its original size in recent years. Faced with a dwindling food supply and a diminishing habitat, the tamarin was nearly extinct 50 years ago. This launched an international effort to breed the monkeys in captivity, along with parallel attempts to conserve their shrinking forest habitat. Markle explains clearly how captive breeding programs initially flailed, producing few offspring that often failed to thrive. The breeding programs became successful only when scientists recognized that tamarins prefer to live in small family-sized groups. Instead of removing the father after the mother gave birth, families were subsequently kept together, and the captive tamarin population began to grow. By the mid-1980s, captive born tamarins were being reintroduced to the now-protected natural habitat. Novel forest-management techniques such as connecting patches of forest with rows of trees continue to increase their range, helping to ensure healthy population growth. The rebound of the golden lion tamarin is truly something to celebrate. —Brent Grocholski


Support GLTs with the MOST Unique Gift!

This holiday season, help us track tamarins in Brazil... and give a unique gift like never before!

You can help us in one of the critical tasks in our efforts to save golden lion tamarins by donating to our Track-A-Tamarin campaign, which supports the purchase of necessary radio telemetry equipment. It costs $10,000 a year to support our scientists in Brazil as they monitor tamarins in their forest habitat. 

Donations to Track-A-Tamarin make a great holiday gift. And all donations to Save the Golden Lion Tamarin are tax deductible! To thank you for your donation, SGLT will send you or your gift recipient a variety of one-of-a-kind tamarin-related items!

For more information, see our sections on donations, great GLT gifts, and how to sponsor a GLT for a loved one.



Jonathan D. Ballou Receives Devra Kleiman Award

We are proud to announce that Jonathan D. Ballou received the Association of Zoos and Aquariums (AZA)’s prestigious Devra Kleiman Scientific Advancement Award. This award, named for its first recipient Devra Kleiman, honors an individual’s long-term commitment to using science-based research and mentoring others. For more than three decades, Dr. Ballou’s pioneering work in conservation genetics has played an instrumental role in conservation of dozens of animal species, including golden lion tamarins. 

Dr. Ballou worked closely for many years with the award’s namesake, Devra Kleiman, on golden lion tamarin conservation at the Smithsonian's National Zoo, where he was the first to create an electronic studbook that is still in use today for this species. Dr. Ballou went on to co-develop the analytical software used by zoos worldwide for the genetic and demographic management of ex situ populations of both threatened and non-threatened species.  He is the co-author of “Introduction to Conservation Genetics,” the first, and very influential textbook in conservation genetics.

In June of this year, Dr. Ballou accepted our invitation to serve as “Special Advisor” on the Board of Directors of Save he Golden Lion Tamarin (SGLT).  In that capacity he works with us to keep golden lion tamarins safe from extinction.


GLTs Carry the Olympic Torch on its way to Rio's 2016 Olympic Games

On its way to the city of Rio to open the Olympic Games, the Olympic flame traveled through coastal Rio de Janeiro state, the region containing the last remaining fragments of Golden Lion Tamarin (GLT) habitat! On Tuesday, August 2 at 11:30AM Rio time, Andreia Martins, Associação Mico-Leão-Dourado biologist, carried the Olympic Torch in the town of Rio Bonito  Together with the Olympic Flame, she carried more than 30 years of experience with golden lion tamarins representing all of us who share in the work of assuring a future for the species in the wild!   

Andreia was selected as an Olympic Torch bearer because she is making a difference in her community.  Coordinator of the Associação Mico-Leão-Dourado GLT Monitoring Team, Andreia has worked in these forests since she was 19 years old, bringing the species back from the brink of extinction by successfully reintroducing zoo-born GLTs to their native forest home.  With the support of partners in Brazil and around the world, the Associação Mico-Leão-Dourado continues to watch over the GLTs and restore and protect enough forest for the species to continue to have a home in Rio de Janeiro into the future.

For more information, please see our press release.

SGLT Announces Two New Special Advisers to the Board

Save the Golden Lion Tamarin is pleased to announce the addition of two Special Advisers to SGLT's Board of Directors.   Dr. Andrew Baker and Dr. Jon Ballou have accepted invitations to serve as advisers for our continuing conservation of golden lion tamarins. Dr. Baker, who has served as the Chief Operating Officer of the Philadelphia Zoo for eight years, brings strong experience in organizational governance, strategic planning, financial management, and fund-raising to his advisory role. Dr. Ballou recently retired as Population Manager and Research Scientist at the Smithsonian Institution's Conservation Biology Institute. He served as the species coordinator and international studbook keeper for GLTs. He continues to serve as an expert adviser for the planning of small population management. Thank you to both!  We are happy to have your valuable contributions.
