The Andean white-eared opossum (Didelphis pernigra) is an opossum species from South America. It is found in the Andes Mountains, ranging from Venezuela to Bolivia. Together with the Guianan white-eared opossum (D. imperfecta), this species was separated from the white-eared opossum (D. albiventris) in 2002, having been included with that species in 1993.

With luck
About 10% of wildlife watchers report an Andean White-eared Opossum sighting in Quito on a given day, based on 10 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

In that month about 30% of wildlife watchers report an Andean White-eared Opossum in Quito on a given day, against under 5% in March–May, August and October, the lowest months. That is one of Quito's driest months, with about 35 mm of rain against 180 mm in April.

GBIF citizen-science records
It is estimated from how often the Andean White-eared Opossum is recorded against all the mammals logged in Quito (10 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.
