The common patas monkey (Erythrocebus patas), also known as the hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. There is some confusion surrounding if there are valid subspecies, with some listing four, others three, and others listing two: the western Erythrocebus patas patas (with a black nose) and the eastern E. patas pyrrhonotus (with a white nose). However, it was later discovered that the nose colour used to separate these subspecies could change to white during pregnancy in females, as well as in general as animals aged, and E. patas pyrrhonotus in Kenya often did not have white noses, thus Mammal Species of the World has classified E. patas as a monotypic species.
The genus status of the species has previously been in flux. Colin Groves first argued the species was closely related to Cercopithecus aethiops in 1989, based on anatomical morphology. Phylogenetic evidence from 2003 appeared to validate him, finding the patas monkey to form a clade within the vervet genus Cercopithecus together with C. aethiops and C. lhoesti, and based on this study Erythrocebus was proposed to be sunk into synonymy...

Possible
About 30% of wildlife watchers report a Patas Monkey sighting in Saloum Delta National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and December
In those months about 40% of wildlife watchers report a Patas Monkey in Saloum Delta National Park on a given day, against under 5% in May–June and August–November, the lowest months. Those are among Saloum Delta National Park's driest months, with almost no rain against 250 mm in August.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Patas 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.
7th of 7
Of the 7 parks where we can rate Patas Monkey sightings, Saloum Delta National Park ranks 7th at about 30%. The best odds are in Murchison Falls National Park (Uganda, about 70%), Kidepo Valley National Park (Uganda, about 70%) and Djoudj National Bird Sanctuary (Senegal, about 70%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Patas Monkey is recorded against all the mammals logged in Saloum Delta National Park (34 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.
