Resum

Cozumel Island is one of the most important tourist destinations in Mexico. Unfortunately, this has been associated with a deterioration of the integrity of essential habitats for native fauna, including the Critically Endangered pygmy raccoon (Procyon pygmaeus). Environmental degradation can affect, among other things, their food availability. Here we focused on examining the diet of the pygmy raccoon in two main subpopulations of the species, by analyzing scat samples and assessing (natural and anthropogenic) food availability. Scat analysis showed that crabs are the dominant component of the pygmy raccoon diet, followed by fruits. The frequency of occurrence correlates with temporal (monthly) food availability. Although anthropogenic food sources can be found in both sampling sites, the availability of natural resources was greater. A better understanding of the diet and food resources availability in their habitats is important to understand the impacts of disturbances on wildlife health, distribution, abundance, and survival.
