African buffalo herd behaviour is one of the most fascinating examples of collective animal decision-making, the massive bovine demonstrating social intelligence unexpected in an animal often seen as simply dangerous. African buffaloes live in herds that can number hundreds of animals, made up mainly of females, calves and young bulls, while older bulls often live in small bachelor groups. Herds move, graze and defend themselves together. In Uganda you can see big herds in Murchison Falls, Queen Elizabeth and Kidepo Valley, and smaller groups in Lake Mburo and even in forests such as Bwindi.

African Buffalo Herd Behaviour: How 1000 Animals Move as One

How a herd decides where to go

Research on African buffaloes found that before moving off to graze, adult females stand up, look in a particular direction and lie down again. The herd then tends to move in the direction most of them faced, a kind of group vote. During the day, herds rest and chew the cud together, and in the dry season they walk long distances to water.

Defence

Buffaloes protect calves and weak animals by bunching together, with adults facing outwards. They respond to calves’ distress calls and will mob lions, sometimes chasing them off a kill or injuring them. Lions often target old bulls that live alone or in small groups, which is why these bulls, called dagga boys, are wary and can be aggressive towards people.

Where to see herds

Large herds gather on the northern bank of Murchison, along the Kazinga Channel in Queen Elizabeth and in Kidepo’s Narus Valley. The gorilla permit costs US$800, or US$600 in April, May and November.

Frequently asked questions

The Voting Behaviour

Research published in 2011 documented that Cape buffalo herds make collective movement decisions by a process that resembles voting. During rest periods, female buffalo stand and gaze in their preferred direction of movement, and the herd moves in the direction indicated by the majority of gazes. This behaviour operates independently of the female’s dominance rank — all votes count equally — and ensures the herd consistently moves toward resources that more individuals know about, drawing on the distributed knowledge of the entire group rather than relying solely on the most dominant individual.

Herd Size and Composition

Cape buffalo herds in Uganda range from small groups of a few dozen to large aggregations of several hundred animals. Large herds provide collective defence against predators — a lion attacking a calf within a large herd must contend with the defensive response of the entire group. Buffalo are well-known for rescuing calves from lion attacks, with adults rushing to assist and sometimes successfully driving off attacking predators. Old bulls leave the main herd and form small bachelor groups or live solitarily, becoming increasingly cranky and unpredictable. These solitary old bulls, called ‘dagga boys’, are responsible for the majority of dangerous encounters with humans.

Daily Routine and Grazing

Buffalo graze primarily at night and during the cooler morning and evening hours, resting and ruminating during the heat of the day. They require daily access to water for drinking and wallowing. In Queen Elizabeth National Park, large herds use the Kazinga Channel as their primary water source, producing the extraordinary wildlife scenes visible from the channel boat trip where herds of hundreds of animals wade and drink together.

Predator Avoidance

Lions are the primary predator of adult buffalo in Uganda’s parks. A healthy adult buffalo in a large herd is rarely killed — predation focuses on calves, old or weakened individuals, and those separated from the herd. The defensive response of an alerted herd — the animals massing together with calves in the centre and adults facing outward — is formidable enough to deter even large lion prides.

Buffalo and Lion Population Dynamics

The relationship between buffalo and lion in Uganda’s national parks is a textbook example of predator-prey population dynamics. Queen Elizabeth’s large buffalo herds support one of East Africa’s densest lion populations, and lion numbers rise and fall in response to buffalo abundance. Years of high buffalo density produce bumper lion breeding seasons; disease events or drought that reduce buffalo numbers are followed by declining lion reproduction. This coupling is visible in long-term wildlife monitoring data, and studying it helps managers predict population trends. The Kasenyi area in Queen Elizabeth, where lion prides are well-studied and buffalo movements are predictable, is one of Africa’s best natural laboratories for observing this dynamic in action.
