With luck
About 10% of wildlife watchers report a Green Crombec sighting in Yaoundé on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 72 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May, August and October
In those months about 10% of wildlife watchers report a Green Crombec in Yaoundé on a given day, against under 5% in April, September and November–February, the lowest months. Those are among Yaoundé's wettest months, with about 180 mm of rain a month against 15 mm in January. March and June–July have too few records to rate.
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.
Among the best
Of the 2 cities where we can rate Green Crombec sightings, Yaoundé ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Kampala (Uganda, about 10%).
Same order: Passeriformes
The closest relatives of the Green Crombec that you can see in Yaoundé (order Passeriformes, Perching Birds) are Common Bulbul (about 90%), Northern Grey-headed Sparrow (about 80%) and Pied Crow (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Crombec is recorded against all the birds logged in Yaoundé (5 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.
