Likely
About 40% of wildlife watchers report a Red-Flanked Duiker sighting in Niokolo-Koba National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 15 mammals 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.
March
In that month about 70% of wildlife watchers report a Red-Flanked Duiker in Niokolo-Koba National Park on a given day, against about 10% in June and November, the lowest months. That is one of Niokolo-Koba National Park's driest months, with almost no rain against 300 mm in August. July to October have too few records to rate.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Red-Flanked Duiker sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Niokolo-Koba National Park, in our data
Niokolo-Koba National Park is the only park on Wallace's Line with enough records to rate Red-Flanked Duiker sightings: about 40% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Red-Flanked Duiker is recorded against all the mammals logged in Niokolo-Koba National Park (12 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.
