With luck
About 10% of wildlife watchers report a Northern Crombec sighting in Niokolo-Koba National Park on a given day, based on 49 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 112th most-seen of the 215 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 20% of wildlife watchers report a Northern Crombec in Niokolo-Koba National Park on a given day, against about 10% in March–April, August–September and November–December, the lowest months. Those are among Niokolo-Koba National Park's driest months, with almost no rain against 300 mm in August. May–July and October have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Northern 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.
7th of 13
Of the 13 parks where we can rate Northern Crombec sightings, Niokolo-Koba National Park ranks 7th at about 10%. The best odds are in Kidepo Valley National Park (Uganda, about 30%), Meru National Park (Kenya, about 30%) and Samburu National Reserve (Kenya, about 30%).
GBIF citizen-science records
It is estimated from how often the Northern Crombec is recorded against all the birds logged in Niokolo-Koba National Park (49 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.
