Abstract
The Panamanian owl monkey (Aotus zonalis) is found from northern Coclé to Darién provinces in Panama, south through the Pacific lowlands of the Chocó biogeographic region, to just north of the Ecuadorian border in Colombia. It is currently listed as Near Threatened on the IUCN Red List. Although much captive research has been conducted, little is known about the current status of wild populations or the species’ actual distribution. We review knowledge of the species conservation ecology and evaluate new data on the presence/absence at 60 sites in Panama, Colombia, and Ecuador and report on anthropogenic activities which may threaten its survival. In combination with the results of previous studies, we found that the species habitat is being reduced by anthropogenic forest clearance, leaving some populations fragmented and susceptible to hunting. Aotus zonalis remains one of the least known primates, and information is needed on its behavior, population dynamics, and ecology.
