GBIF citizen-science records
It is estimated from how often the Sharp-tailed Sandpiper is recorded against all the birds logged in Panama City (33 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.
