Rare
Under 5% of wildlife watchers report a Merriam's Piñon Mouse sighting in Mexico City on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 19 mammals we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Merriam's Piñon Mouse in Mexico City on a given day, so our monthly data shows no clear season.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Merriam's Piñon Mouse sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Merriam's Piñon Mouse is recorded against all the mammals logged in Mexico City (6 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.
