Chimpanzee Behavior: Tool Use, Hunting, and Social Life

Chimpanzees are among Africa’s most intelligent and socially complex animals. Their ability to use tools, cooperate during hunting, communicate through different sounds and maintain strong relationships makes them fascinating to observe in the wild.

Understanding chimpanzee behaviour helps you appreciate how these primates survive in tropical forests, organise their communities and interact with their surroundings.

Chimpanzees share a close evolutionary relationship with humans. However, their lives are shaped by wild environments, competition for food, social relationships and the need to avoid danger.

In East Africa, Uganda and Tanzania offer excellent opportunities to observe wild chimpanzees through guided tracking experiences.

Understanding Chimpanzee Behaviour in the Wild

Chimpanzees, scientifically known as Pan troglodytes, are great apes that inhabit tropical forests and woodland environments across parts of Africa.

They possess strong arms, flexible hands and highly developed problem-solving abilities.

Unlike monkeys, chimpanzees do not have tails.

They move through trees using their hands and feet but also spend considerable time travelling on the ground.

Chimpanzees display different behaviours depending on their age, sex, social position and environment.

Some activities involve cooperation, while others reflect competition between individuals.

Researchers have documented complex social relationships, learning abilities and differences in behaviour between chimpanzee populations.

Chimpanzee Tool Use: How They Solve Problems

One of the most remarkable aspects of chimpanzee behaviour is their ability to use tools.

Wild chimpanzees have been observed selecting and modifying natural objects to complete particular tasks.

Their tool use demonstrates planning, practical learning and an understanding of how objects can help them obtain food.

1. Using Sticks to Collect Termites

Some chimpanzee populations use thin sticks or plant stems to collect termites.

They insert a suitable tool into a termite opening and withdraw it when insects attach themselves.

The chimpanzee then removes the termites using its mouth.

This behaviour requires coordination and careful tool selection.

Young chimpanzees may spend considerable time observing experienced individuals before mastering the technique.

2. Using Leaves as Sponges

Chimpanzees in some populations use leaves to collect drinking water.

They chew or fold leaves into a suitable shape and dip them into water.

The soaked leaves are then placed inside the mouth.

This behaviour allows chimpanzees to obtain water from places where drinking directly would be difficult.

3. Breaking Open Hard Foods

Certain chimpanzee populations use stones or pieces of wood to crack nuts.

They place the nut against a firm surface and strike it with another object.

This technique is especially well documented in parts of West Africa.

Importantly, not every chimpanzee population uses the same tools.

Tool traditions vary between communities, reflecting differences in local conditions and socially learned behaviour.

How Young Chimpanzees Learn Tool Use

Young chimpanzees learn many skills by watching older individuals.

Mothers play an important role in this process.

Infants remain close to their mothers and observe feeding techniques, movements and social interactions.

Learning complicated skills can take several years.

You may notice a young chimpanzee attempting to copy an adult’s actions.

However, tool use is not guaranteed during a tourist tracking experience.

Many observations require extended research periods.

Chimpanzee Hunting Behaviour

Although chimpanzees eat considerable amounts of fruit and other plant foods, they are omnivores.

Their diet may include insects, leaves, flowers, seeds and meat.

Some communities regularly hunt smaller mammals.

What Animals Do Chimpanzees Hunt?

Chimpanzees have been recorded hunting several species, including monkeys.

Red colobus monkeys are important prey in some East African forests.

Researchers studying chimpanzees in Uganda’s Kibale National Park have documented coordinated hunting behaviour.

However, hunting frequency varies considerably between communities.

Cooperative Hunting

During some hunts, several chimpanzees participate in pursuing prey.

Individuals may approach from different directions or occupy positions that restrict escape routes.

Adult males frequently participate in hunting, although other community members may also become involved.

Cooperation can increase hunting opportunities.

However, chimpanzee hunts do not always involve carefully coordinated roles.

Some hunts develop quickly when suitable prey becomes available.

Meat Sharing Among Chimpanzees

Chimpanzees sometimes share meat after successful hunts.

Individuals may approach the animal holding the food and request a portion.

Sharing patterns depend on social relationships, participation in hunting and other circumstances.

Meat sharing can involve cooperation, competition and social negotiation.

However, chimpanzees do not distribute food equally among all community members.

Their behaviour reflects complicated relationships rather than a fixed system of sharing.

Chimpanzee Social Structure

Chimpanzees live in communities containing several adult males, females and younger animals.

Community size varies considerably between habitats.

Unlike gorillas, chimpanzees do not normally travel together as one permanent group.

Instead, members form smaller temporary parties that change throughout the day.

This arrangement is known as a fission-fusion social system.

How Chimpanzee Parties Form

Chimpanzees may separate into smaller groups while searching for food.

Later, individuals reunite with other community members.

Party composition changes according to food availability, reproductive conditions and social relationships.

You may therefore encounter only a few chimpanzees during a trek, even when the wider community contains many individuals.

Male Relationships

Adult male chimpanzees commonly remain within their birth communities.

They develop relationships involving cooperation, competition and dominance.

Some males maintain strong alliances.

These relationships can influence social position and interactions with neighbouring communities.

Female Relationships

Female chimpanzees may transfer between communities when they mature.

Adult females often spend considerable time feeding with their dependent offspring.

Their social relationships vary between populations and individuals.

Chimpanzee Grooming and Social Bonds

Grooming is an important part of chimpanzee social behaviour.

Individuals carefully examine another chimpanzee’s fur, removing dirt, parasites or loose material.

However, grooming also helps maintain relationships.

Why Chimpanzees Groom Each Other

Grooming can strengthen social bonds and reduce tension.

Individuals may groom relatives, allies or other community members.

The activity sometimes continues for extended periods.

During tracking, you may observe two chimpanzees sitting together while grooming.

These quiet interactions provide excellent opportunities to understand their social relationships.

How Chimpanzees Communicate

Chimpanzees communicate through sounds, facial expressions, gestures and body movements.

Different signals help individuals maintain contact, express excitement or respond to threats.

Pant-Hoot Calls

Pant-hoots are among the most recognisable chimpanzee vocalisations.

These calls may begin quietly before becoming louder.

They help chimpanzees communicate across forest distances.

You may hear several individuals responding to one another.

Drumming on Trees

Chimpanzees sometimes strike tree trunks or large roots with their hands and feet.

The resulting sounds can travel through the forest.

Drumming may accompany vocal communication or other social activities.

Facial Expressions and Gestures

Chimpanzees use gestures such as reaching, touching and arm movements.

Facial expressions also provide information about emotional and social situations.

Interpreting these behaviours requires attention to the surrounding circumstances.

Mother and Infant Relationships

Chimpanzee infants depend heavily on their mothers.

During early life, infants travel while holding onto their mothers.

As they develop, they begin exploring nearby branches and interacting with other young chimpanzees.

Mothers provide protection, food access and opportunities to learn essential skills.

These relationships commonly continue for several years.

Where to Observe Chimpanzee Behaviour in East Africa

Several protected forests offer opportunities for guided chimpanzee tracking.

Sightings depend on animal movements, weather and tracking conditions.

Kibale National Park

Kibale is among Uganda’s best-known chimpanzee tracking destinations.

Visitors may observe feeding, grooming, vocal communication and movement through trees.

Gombe and Mahale Mountains

These Tanzanian destinations are internationally recognised for chimpanzee research and wildlife observation.

Their forest habitats provide opportunities to study natural behaviour.

Tips for Observing Chimpanzees Responsibly

Chimpanzees are powerful wild animals that require careful observation.

Follow these guidelines:

• Track chimpanzees with authorised guides.

• Maintain the required viewing distance.

• Avoid direct physical contact.

• Never feed chimpanzees.

• Keep your voice low.

• Avoid flash photography.

• Follow current health requirements.

• Do not track when suffering from potentially contagious illness.

Chimpanzees can contract some human diseases, making responsible tourism particularly important.
