Likely
About 40% of wildlife watchers report a Black-rumped Waxbill sighting in Niokolo-Koba National Park on a given day, based on 147 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 215 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
In that month about 50% of wildlife watchers report a Black-rumped Waxbill in Niokolo-Koba National Park on a given day, against about 30% in April, August–September and November–December, the lowest months. That is one of 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 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Black-rumped Waxbill sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Black-rumped Waxbill sightings, Niokolo-Koba National Park has the highest daily chance: about 40%. Next come Murchison Falls National Park (Uganda, about 20%) and Kidepo Valley National Park (Uganda, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-rumped Waxbill is recorded against all the birds logged in Niokolo-Koba National Park (147 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.
