There have been numerous studies about Spectacled bear´s diet, however little is known about the small vertebrates it consumes. This study present nine vertebrate species (seven rodent and two birds) as preys of the Spectacled bear, based on the analysis of six feces collected from two locations Upa (Amazonas) and Lagunas Arreviatadas (Cajamarca) in northern Peru. Six of these records were new food items and a new family Caviidae. Vertebrates were found only in the Upa location. Additionally a sampling of small non flying mammals was conducted in there. Our results suggest that the Spectacled bear would be a generalist species. It prefers plants, however if it finds vertebrates in the environment, it could feed on them.

Neusticomys peruviensis (Musser & Gardner 1974) es una especie de roedor acuático perteneciente a la tribu Icthyomyini, es una especie endémica de Perú. Fue previamente conocida por tres especímenes, el espécimen tipo proviene de Balta, otro espécimen del Rio Shesha, ambos ubicados en el departamento de Ucayali y un tercer espécimen de Pakitza (departamento de Madre de Dios). Nosotros capturamos un espécimen adicional en el departamento de Cusco, con esto se extiende su distribución geográfica a 82.15 km al sur de su rango de distribución. Se necesitan más estudios detallados para conocer la ecología y la distribución de este roedor.

Neusticomys peruviensis (Musser & Gardner 1974) is a semi aquatic rodent which belongs to the Ichthyomyini Tribe. It is an endemic species of Peru, previously known for three specimens: type specimen from Balta, another specimen from Rio Shesha, both from Ucayali department; and the third specimen from Pakitza (Madre de Dios department). We captured an additional specimen in Cusco Department. Its geographic distribution extends 84.15 km south of the previously known distribution range.  This suggest that this species would have a broader distribution. More detailed studies are needed to know the ecology and distribution of these rodents.
