Where does the Dall Sheep sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Dall Sheep is recorded against all the mammals logged in Kluane National Park (70 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.
