About Didelphis albiventris Lund, 1840
The white-eared opossum (Didelphis albiventris Lund, 1840) weighs between one and three pounds. It has black and grey fur, with white hair covering its ears and face, and dark hair covering its long tail. It is omnivorous, and feeds on invertebrates, small vertebrates, and fruits. White-eared opossums inhabit open areas, mountains, and deciduous forests. They are commonly found in Argentina, Paraguay, Uruguay, Bolivia, Brazil, the Andes, and the humid forests of Guyana, Suriname, and southern Venezuela. These habitats have widely differing environmental characteristics, including rainfall, humidity, water balance, and temperature. The white-eared opossum frequently changes its habitat based on its breeding season. Population densities are usually higher in wetter seasons, when young opossums are weaned and begin leaving to forage for food. While the species is typically solitary and nomadic, some individuals will gather in groups in burrows, holes, empty garbage, or even under houses.
