## Overview

The collared mangabey is a fascinating primate that inhabits the dense rainforests and swamp forests of western and central Africa. This medium-sized monkey is characterized by its unique reddish-brown to grey fur and the distinctive white collar around its neck that gives the species its name. With long legs and a powerful build, the collared mangabey is well adapted for moving through the dense undergrowth of the rainforest, where it spends considerable time on the ground – more than most other African monkeys.

These intelligent animals are masters at finding and opening hard nuts and seeds with their powerful jaws and large molars. They have developed impressive techniques for cracking nuts that most other animals cannot access. The collared mangabey plays an important role in the forest ecosystem by dispersing seeds from the fruits they eat and by digging for roots and tubers, which helps aerate the soil.

Socially, collared mangabeys live in groups led by both males and females together. Groups can consist of 10-35 individuals who communicate with each other through a variety of calls, facial expressions, and body language. They have a complex social life with strong bonds between group members, especially between mothers and their young who stay close together for several years.

Unfortunately, the collared mangabey is threatened by deforestation and hunting for bushmeat. Their habitats are rapidly shrinking as rainforests are converted to agricultural land. Although the species still occurs in several African countries, populations are declining and conservation efforts are important to secure their future in the wild.

## Quick facts

- Weight: 5.5–13 kg
- Length: 45–67 cm
- Lifespan: 20–30 yrs
- Diet: Omnivore
- Conservation Status: Least Concern

## Habitat

The collared mangabey lives primarily in dense rainforests and wetlands in western and central Africa, particularly in countries like Nigeria, Cameroon, Gabon, Congo, and Equatorial Guinea. They prefer areas with dense undergrowth near rivers and swamps, where they can find abundant food year-round. These environments offer both protection from predators and a rich supply of fruits, nuts, seeds, and insects.

In these dense forests, collared mangabeys move between ground level and the lower tree canopy. They are particularly associated with flooded forests and coastal mangrove forests, where they have adapted to foraging both on land and in water. Their ability to swim and wade allows them to exploit habitats that other monkeys avoid.

## Seasonal Behavior

In the equatorial rainforests where collared mangabeys live, there is no distinct seasonal cycle like in more northern regions, but there are seasonal variations in rainfall. During rainy periods, certain parts of their habitat become flooded, affecting where they search for food. During drier periods, they concentrate more on areas near permanent water sources. Fruit production in the forest varies throughout the year, and collared mangabeys adjust their diet according to availability – eating more nuts and seeds when fruits are less available and more fruits when they are in season.

- Population: Unknown, but decreasing

## Did you know?

- Collared mangabeys can crack nuts so hard that they sometimes use stones as tools – just like humans!
- They have special cheek pouches where they can store food while eating, much like a hamster!
- Collared mangabeys are excellent swimmers and are not afraid of water, which is unusual among monkeys.
- When communicating with each other, they use over 20 different calls, each with its own meaning!
- Infants are born with lighter fur than their parents and become darker as they grow up.
- They can leap up to 4 meters from branch to branch when traveling through the trees!
- Collared mangabeys have an excellent sense of smell that helps them find hidden food under leaves and soil.
- They spend about one-third of their time on the ground – more than most other African monkeys!
