The red-tailed monkey (Cercopithecus ascanius), also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon, is a species of primate in the family Cercopithecidae.

The red-tailed monkey is usually black, red, or orange. Although native to this region, it has spread north and south as well as it can survive in different habitats and under different conditions. It is a distinct creature in its habitats and is gradually becoming endangered due to deforestation and over-exploitation through hunting and predation.
There are five subspecies recognized for this species: Cercopithecus ascanius ascanius Cercopithecus ascanius atrinasus Cercopithecus ascanius katangae Cercopithecus ascanius whitesidei Cercopithecus ascanius schmidti The red-tailed monkey is named as it sounds: for the red coloration of the tail's underside.

Possible
About 30% of wildlife watchers report a Red-tailed Monkey sighting in Kampala on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 7 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report a Red-tailed Monkey in Kampala on a given day, against under 5% in February, April, July and October, the lowest months. That is one of Kampala's driest months, with about 65 mm of rain against 190 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Red-tailed 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.
Only Kampala, in our data
Kampala is the only city on Wallace's Line with enough records to rate Red-tailed Monkey sightings: about 30% of wildlife watchers there report one on a given day.
Same family: Cercopithecidae
The closest relatives of the Red-tailed Monkey that you can see in Kampala (family Cercopithecidae, Old World Monkeys) are Mantled Guereza (about 60%), Tantalus Monkey (about 30%) and Vervet Monkey (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-tailed Monkey is recorded against all the mammals logged in Kampala (25 verified sightings), 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.
