It is the 356th most-seen of the 366 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year

GBIF citizen-science records
It is estimated from how often the Slender-billed Starling is recorded against all the birds logged in Kibale National Park (9 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.
