Possible
About 30% of wildlife watchers report an Island Mouse sighting in Ranomafana National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 14 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report an Island Mouse in Ranomafana National Park on a given day, against under 5% in April–August and December, the lowest months. That is one of Ranomafana National Park's wettest months, with about 430 mm of rain against 80 mm in September.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Island Mouse sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Island Mouse sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Island Mouse is recorded against all the mammals logged in Ranomafana National Park (11 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.
