Likely
About 40% of wildlife watchers report a Green Crombec sighting in Kibale National Park on a given day, based on 665 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 366 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January and April
In those months about 50% of wildlife watchers report a Green Crombec in Kibale National Park on a given day, against about 30% in February and November, 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.
2nd of 8
Of the 8 parks where we can rate Green Crombec sightings, Kibale National Park ranks 2nd at about 40%. The best odds are in Semuliki National Park (Uganda, about 50%).
GBIF citizen-science records
It is estimated from how often the Green Crombec is recorded against all the birds logged in Kibale National Park (665 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.
