Mammals

Fifty Five mammal species have been recorded on the reserve, including 14 bat species, and carnivores such as Puma and Ocelot.

The Puma and the Sloth

Field work along the REGUA trails has come up with some fascinating ecological detail. Fellow mammals puma and sloth inhabit the same rainforest habitat, one on the ground, the other high in the canopy, and you would not expect them to meet. However, study of puma faeces at REGUA has shown that it contains sloth hairs suggesting that pumas eats sloths. That sloths spend most of their time in the canopy is sensible for a slow moving mammal, but when it comes to the ground to defecate it is at its most vulnerable. Unfortunately for some of the REGUA sloths their irregular forays to the rainforest floor means they are caught unawares by the puma. Populations of sloths at REGUA appear to be very healthy although no quantitative data is available yet, and this is despite the happy return of the puma which is probably encouraged by the decline in hunting. In terms of rarity, the puma is far rarer at REGUA than sloth, but is less likely to be seen. You can help sloths at REGUA if you follow the link on the Links page.
