Ocelot Leopardus pardalis is one of the most widespread species in America. Nevertheless, its ecology, distribution and population status are not well known in several countries, including Costa Rica. Here we present the first published population density estimations in Costa Rica and the first effort for the Caribbean slope of the country. Using camera-trapping, we estimated ocelot density through capture-recapture analysis within the Talamanca-Caribbean Biological Corridor. An abundance of 8 and 5 individuals were estimated by Mo and Mh models, respectively. Based on previous home-range studies, three Effective Sampling Areas (ESA) were used to estimate absolute density. Density was calculated in 8.95, 10.33 and 11.61 individuals (Mo model) and 5.59, 6.45 and 7.25 (Mh model) individuals × 100 km^-2 for the maximum, mean and minimum ESA estimates, respectively. Gross extrapolations of the expected population size indicate a low abundance and codependence between the corridor and surrounding areas for the long term maintenance of the species in the region.
