The sooty mangabey (Cercocebus atys) is an Old World monkey found in forests from Senegal in a margin along the coast down to the Ivory Coast. Until 2016, Cercocebus atys was considered a single species of mangabey, with two subspecies: Cercocebus atys atys (now Cercocebus atys) and Cercocebus atys lunulatus. After assessment by the International Union for Conservation of Nature (IUCN) in 2016, Cercocebus atys lunulatus was declared a separate species (Cercocebus lunulatus). Both Cercocebus atys and Cercocebus lunulatus were formerly considered subspecies of the widespread Cercocebus torquatus.
Cercocebus atys atys, now Cercocebus atys, is commonly known as the sooty mangabey and is situated west of the Sassandra River in the Ivory Coast up to Senegal. Cercocebus atys lunulatus, now Cercocebus lunulatus, is commonly known as the white-crowned, white-naped, or white-collared mangabey (leading to confusion with the collared mangabey). This now distinct species is considered to have a geographic range east of the Sassandra River to the west of the Volta River in Ghana; Cercocebus lunulatus is also recorded as inhabiting forests in southwestern Burkina Faso and northeastern...

Likely
About 50% of wildlife watchers report a Smoky Mangabey sighting in Taï National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 14 mammals we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a Smoky Mangabey in Taï National Park on a given day, against about 10% in March, the lowest month. October and December–February have too few records to rate.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Smoky Mangabey sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Taï National Park, in our data
Taï National Park is the only park on Wallace's Line with enough records to rate Smoky Mangabey sightings: about 50% of wildlife watchers there report one on a given day.
Same family: Cercopithecidae
The closest relatives of the Smoky Mangabey that you can see in Taï National Park (family Cercopithecidae, Old World Monkeys) are Western Red Colobus (about 60%), Diana Monkey (about 50%) and King Colobus (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Smoky Mangabey is recorded against all the mammals logged in Taï National Park (11 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.
