Filoha Hamadryas Project

The Filoha Hamadryas Project focuses on the behavioral biology and socioecology of wild hamadryas baboons at the Filoha field site in Ethiopia.  The project began in 1996 with Larissa Swedell's PhD research, based at Columbia University and supervised by Dr. Marina Cords, and has been facilitated by and conducted in collaboration with the Awash National Park Baboon Research Project (co-directed by Drs. Clifford Jolly and Jane Phillips-Conroy and ongoing since 1973), the Ethiopian Wildlife Conservation Authority (formerly the Ethiopian Wildlife Conservation Organization), and Addis Ababa University.  

The Filoha Hamadryas Project is the first (and only) long-term field study of hamadryas baboons since the work of Hans Kummer and his students Jean-Jacques Abegglen, Hans Sigg, and Alex Stolba at nearby Erer Gota in the 1970's.  We integrate behavioral observations with genetic data in collaboration with with Dr. Linda Vigilant and Veronika Städele at the Max Planck Institute for Evolutionary Anthropology, endocrine data in collaboration with Dr. Jacinta Beehner at the University of Michigan, and nutritional data in collaboration with Dr. Jessica Rothman at Hunter College-CUNY.  We welcome additional collaborations, as well as interested students and volunteers.  Please see our current volunteer solicitation on Primate Info Net ( and contact Larissa Swedell if you are interested. 

Funding for the Filoha Hamadryas Project over the past 20 years has been generously granted by the Leakey Foundation, the Wenner-Gren Foundation, the National Geographic Society and the National Science Foundation.
