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.

About 20% of wildlife watchers report a White-eared Opossum sighting in Montevideo on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the most-seen of the 5 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March and October
In those months about 40% of wildlife watchers report a White-eared Opossum in Montevideo on a given day, against under 5% in May–August and November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most White-eared Opossum sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.

GBIF citizen-science records
It is estimated from how often the White-eared Opossum is recorded against all the mammals logged in Montevideo (18 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.
