A 3-month field study was conducted in Panama to determine presence and relative abundance of Saguinus geoffroyi, the Geoffroy's tamarin, and status of its habitat (see Acknowledgments for taxonomic note). This primate has a wide geographical distribution in eastern Panama; however, local distribution is highly variable. Tropical forest habitat is rapidly being converted for agriculture and timber. Areas where human access was strictly limited showed tamarin densities significantly greater than in less protected areas. Disturbance has a distinct impact on population densities. There may also be a relationship between tamarin abundance and specific types of vegetation. Future actions regarding the conservation of S. geoffroyi and its habitat are recommended.
