The white-eared opossum (Didelphis albiventris), known as the timbu and cassaco in northeast Brazil, saruê and sariguê in Bahia, micurê and mucura in northern Brazil and comadreja overa and zarigüeya in Argentina, is an opossum species 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.
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. From 1993 until 2002, this species also included the Guianan white-eared opossum (D. imperfecta) and the Andean white-eared opossum (D. pernigra) as subspecies.
It is the team mascot of Clube Náutico Capibaribe, a Brazilian football team from Recife, Pernambuco. The white-eared opossum is about one to three pounds in weight and has black and grey fur, with white hair covering their ears and face, and dark hair on their long tails. They are omnivorous, feeding on invertebrates, small vertebrates, and fruits.

GBIF citizen-science records
It is estimated from how often the White-eared Opossum is recorded against all the mammals logged in Buenos Aires (278 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
