Very likely
About 80% of wildlife watchers report a Mount Kilimanjaro Guereza sighting in Arusha National Park on a given day, based on 130 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 16 mammals we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
September
In that month about 90% of wildlife watchers report a Mount Kilimanjaro Guereza in Arusha National Park on a given day, against about 50% in May, the lowest month. That is one of Arusha National Park's driest months, with about 65 mm of rain against 440 mm in April.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mount Kilimanjaro Guereza 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 Arusha National Park, in our data
Arusha National Park is the only park on Wallace's Line with enough records to rate Mount Kilimanjaro Guereza sightings: about 80% of wildlife watchers there report one on a given day.
Same family: Cercopithecidae
The closest relatives of the Mount Kilimanjaro Guereza that you can see in Arusha National Park (family Cercopithecidae, Old World Monkeys) are Blue Monkey (about 80%) and Olive Baboon (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mount Kilimanjaro Guereza is recorded against all the mammals logged in Arusha National Park (130 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.
