Cayo Santiago Field Station is a beautiful 15.2 ha (38 acre) island located 1 km off the southeastern coast of Puerto Rico which is inhabited by a free-ranging colony of rhesus monkeys, used primarily for behavioral, demographic, genetic, and physiological research. Skeletons from Cayo Santiago monkeys are maintained at the Laboratory for Primate Morphology and Genetics (LPMG).

The rhesus monkey colony at Cayo Santiago was founded in 1938. The colony was established to provide a field site for behavioral investigations and to supply rhesus monkeys for biomedical research and anatomical studies at stateside laboratories. When the National Institutes of Health (NIH) Laboratory of Perinatal Physiology (LPP) was opened in San Juan, Puerto Rico in 1956, Cayo Santiago became the Primate Ecology Section of the Laboratory of Perinatal Physiology. Daily census and longitudinal demographic database began in 1957 and has been maintain since.
