Red-tailed monkey Uganda is one of the most commonly encountered primates in Uganda’s forest national parks, the bold white cheek patches and rust-red tail making it easy to identify in the forest canopy. The red-tailed monkey is a small, lively forest monkey with a white heart-shaped nose spot, white cheeks and a chestnut-red tail. It is one of the most common monkeys in Uganda’s forests, including Kibale, Bwindi, Budongo, Mabira and Semuliki, and is seen on most gorilla and chimp treks. It also lives in forest patches around Entebbe and Kampala.

Habits

Red-tailed monkeys live in groups of about 10 to 35, with a single adult male, and spend their days in the middle and upper canopy. They eat fruit, insects, flowers and leaves, and store food in cheek pouches so they can feed quickly and move on. They often join mixed groups with blue monkeys, red colobus and mangabeys, sharing the job of watching for crowned eagles and chimpanzees.

Hybrids

In parts of Kibale, red-tailed monkeys interbreed with blue monkeys, and hybrid animals with mixed features turn up in some groups. This is one of the best-known cases of hybridisation among wild monkeys.

Where to see it

Watch the canopy on any forest walk in Kibale or Bwindi, and on the Bigodi swamp walk. The gorilla permit costs US$800, or US$600 in April, May and November. See our guides to Kibale Forest, Bwindi, the blue monkey and Kibale animals.

Frequently asked questions

Distribution in Uganda

The red-tailed monkey is found across Uganda’s forest zone, including Kibale National Park, Bwindi Impenetrable National Park, Budongo Forest, and forest patches throughout the western Rift Valley and central regions. It is one of the most abundant primates in Kibale, where groups of 20 to 40 animals are regularly encountered on chimpanzee tracking walks and forest nature walks. The species occurs in both primary and secondary forest and tolerates some degree of forest degradation better than more specialist primates.

Behaviour and Ecology

Red-tailed monkeys live in mixed-sex groups with a single adult male. They are highly vocal and active, moving quickly through the mid- and upper canopy in search of fruit, insects, and young leaves. They frequently associate with other primate species — particularly blue monkeys and grey-cheeked mangabeys in Kibale — in mixed groups that provide enhanced predator detection. Crowned hawk-eagles are their most significant predator, and the monkeys respond to eagle alarm calls with explosive flight.

Conservation Status

The red-tailed monkey is classified as Least Concern by the IUCN and is common across central Africa. Uganda’s forest park populations are stable and easily observed.

Kibale and Bwindi Viewing

Red-tailed monkeys are one of the most reliable primate sightings in Kibale National Park, encountered on virtually every forest walk. They are also common in Bwindi and at the Bigodi Wetland Sanctuary boardwalk. The species’ boldness compared to other forest monkeys means it is often the first primate encountered on any Uganda forest walk.

Red-Tailed Monkey: Species in Context

The red-tailed monkey belongs to the large genus Cercopithecus (guenons), which includes over 20 African forest monkey species. In Uganda’s forests, the guenons are represented by the red-tailed monkey, blue monkey, L’Hoest’s monkey, De Brazza’s monkey, and Mona monkey (in the Semliki area). These species show remarkable diversity in colour pattern while maintaining the basic guenon body plan — a small to medium-sized omnivorous forest monkey with a long tail and a diet based on fruit, leaves, and insects. The red-tailed monkey’s bold white cheek patches and rusty tail make it one of the most easily identified of Uganda’s forest monkeys and a reliable species for visitors new to African forest birding and wildlife.

Red-tailed monkeys in Uganda are found in all of the country’s major forest national parks, and are encountered on virtually every Bwindi gorilla trekking day. The species is active and vocal, and groups of 20 to 40 individuals move through the forest canopy at noticeable speed, the red tail providing an easy identification point as they leap between trees. In Kibale National Park, red-tailed monkeys are present in high density and are regularly seen joining multi-species primate groups at fruiting trees alongside blue monkeys, red colobus, and grey-cheeked mangabeys. Their tolerance of moderate human disturbance makes them among the most approachable of Uganda’s forest primates.
