The La Parguera, Puerto Rico colony: establishment and early studies

Two islands off the southwest coast of Puerto Rico, La Cueva and Guayacan, were populated with monkeys derived from the Cayo Santiago colony and new imports from India during 1962-1963. This colony became known as the La Parguera Colony due to its proximity to the fishing village of La Parguera. Initial work on the island focused on studies of group formation and dynamics. Later, attention turned to field experiments on the interaction of behavior and hormones in coordinating reproduction and a number of other behavioral studies.
