The vervet monkey (Chlorocebus pygerythrus), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in body length from about 40 cm (16 in) for females, to about 50 cm (20 in) for males.
In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males moving to other groups at the time of sexual maturity. Studies done on vervet monkeys involve their communication and alarm calls, specifically in regard to kin and group recognition, and particular predator sightings.
The vervet monkey was previously classified as Cercopithecus aethiops, now renamed 'grivet... Wikipedia →

Possible
About 30% of wildlife watchers report a Vervet Monkey sighting in Nyungwe National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 11 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.
February
In that month about 60% of wildlife watchers report a Vervet Monkey in Nyungwe National Park on a given day, against about 10% in April–June and September–January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Vervet 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.
31st of 36
Of the 36 parks where we can rate Vervet Monkey sightings, Nyungwe National Park ranks 31st at about 30%. The best odds are in Tarangire National Park (Tanzania, about 80%), Akagera National Park (Rwanda, about 70%) and Lake Nakuru National Park (Kenya, about 70%). All parks ranked.
Same family: Cercopithecidae
The closest relatives of the Vervet Monkey that you can see in Nyungwe National Park (family Cercopithecidae, Old World Monkeys) are L'Hoest's Guenon (about 80%), Blue Monkey (about 70%) and Olive Baboon (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vervet Monkey is recorded against all the mammals logged in Nyungwe National Park (8 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.
