Rare
Under 5% of wildlife watchers report a Green Crombec sighting in Murchison Falls National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 293rd most-seen of the 424 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Green Crombec in Murchison Falls National Park on a given day, against under 5% in August to June, 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.
6th of 8
Of the 8 parks where we can rate Green Crombec sightings, Murchison Falls National Park ranks 6th at under 5%. The best odds are in Semuliki National Park (Uganda, about 50%), Kibale National Park (Uganda, about 40%) and Bwindi Impenetrable National Park (Uganda, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Crombec is recorded against all the birds logged in Murchison Falls National Park (20 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.
