Very likely
About 80% of wildlife watchers report a Bolivian Big-eared Mouse sighting in Lauca National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 5 mammals we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
May
In that month about 90% of wildlife watchers report a Bolivian Big-eared Mouse in Lauca National Park on a given day, against about 20% in April, the lowest month. That is one of Lauca National Park's driest months, with almost no rain against 150 mm in January. August has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Bolivian Big-eared Mouse sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate Bolivian Big-eared Mouse sightings: about 80% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bolivian Big-eared Mouse is recorded against all the mammals logged in Lauca National Park (42 verified sightings from 2019 to 2026), 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.
