Likely
About 40% of wildlife watchers report a Dent’s Monkey sighting in Nyungwe National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 11 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
July and December
In those months about 50% of wildlife watchers report a Dent’s Monkey in Nyungwe National Park on a given day, against about 10% in January–March, May–June and September–November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dent’s Monkey 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 2
Of the 2 parks where we can rate Dent’s Monkey sightings, Nyungwe National Park ranks 2nd at about 40%. The best odds are in Semuliki National Park (Uganda, about 70%).
GBIF citizen-science records
It is estimated from how often the Dent’s Monkey is recorded against all the mammals logged in Nyungwe National Park (10 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.
