Preliminary data of primate feeding behaviour on the continental island of Coiba was collected as a baseline study of feeding behaviour in Cebus imitatorat coastal sites. Coiba Island is located on the South Pacific side of Panama, in the Chiriquí Gulf. It is a continental island and the biggest in the Mesoamerican region of the Pacific, it has an area of 503 km². This is a preliminary survey to identify basic feeding behaviour that could be measured in the future as a part of our ethogram to study C. imitator, as part of our long-term project on Coiba Island. We identified four feeding skills by C. imitator outside the forest: Hammering shells or skilledpounding,removing rocks, eating mangrove fruits, and pounding Cocos nucifera on an anvil. Using anvils seemed to be the most effective method to obtain food spending 51% of the time eating using this technique and only 28% moving to find a coconut, 18% invested in pounding the fruit, and just 3% on keeping vigil. Spending time outside the coast of a continental island seemed to be a benefical technique for C. imitator to survive. Further studies will be conducted by Fundación Pro-Conservación de los Primates Panameños (FCPP) to understand the predation-feeding-competition theory its implications for foraging techniques by C.imitator in an island habitat.
