Didelphis albiventris (White-eared Opossum)

Wikipedia Abstract

The white-eared opossum (Didelphis albiventris) is an opossum species from South America. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. It is a terrestrial and, sometimes, arboreal animal, and a habitat generalist, living in a wide range of different habitats. It's an omnivorous animal, feeding on invertebrates, small vertebrates, fruits and plants. For some time, this species was incorrectly known by the name D. azarae, correctly applied to the big-eared opossum. This led to azarae's discontinuation as a species name.
