With luck
About 10% of wildlife watchers report a Green Crombec sighting in Bwindi Impenetrable National Park on a given day, based on 183 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 146th most-seen of the 400 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March and December
In those months about 20% of wildlife watchers report a Green Crombec in Bwindi Impenetrable National Park on a given day, against under 5% in January and February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Green Crombec sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 8
Of the 8 parks where we can rate Green Crombec sightings, Bwindi Impenetrable National Park ranks 3rd at about 10%. The best odds are in Semuliki National Park (Uganda, about 50%) and Kibale National Park (Uganda, about 40%).
GBIF citizen-science records
It is estimated from how often the Green Crombec is recorded against all the birds logged in Bwindi Impenetrable National Park (183 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.
