African buffalo | Exploring the World of Wildlife: facts about the African buffalo

The African buffalo (Syncerus caffer) is one of the continent’s most iconic large herbivores, playing a critical role in the ecosystems where they live.

There are several subspecies of African buffalo, including the Cape buffalo, the forest buffalo, and the Sudanese buffalo. Each subspecies is adapted to its specific environment and has distinguishing physical characteristics.

There are also lesser-known subspecies like the Nile buffalo (Syncerus caffer aequinoctialis) and the mountain buffalo (Syncerus caffer mathewsi), each with its own distinct characteristics and habitat preferences.

Each subspecies has evolved specific traits to survive and thrive in its environment, showcasing the adaptability and diversity of the African buffalo across the continent.

Despite being a herbivore, the African buffalo is known to fiercely defend itself and its herd from predators, even capable of fending off lion prides.

The African buffalo’s reputation as a formidable defender is well-deserved.

African buffaloes thrive in numbers. When threatened, they form a defensive formation with the stronger, larger individuals facing the threat and the young or weaker members positioned in the center. This formation is effective against predators and can be intimidating even to the fearsome lion.

Lions are one of the primary predators of African buffaloes, especially targeting the young or weak. However, hunting a buffalo is risky. A buffalo can use its sharp horns and massive strength to injure or kill a lion. There are numerous documented instances where buffaloes have successfully warded off multiple lions or even rescued a member of their herd from the jaws of lions.

African buffaloes are known to have good memories. They can remember individuals, including humans, who have harmed them or posed threats, and there are tales of buffaloes seeking out specific individuals for retaliation.

Female buffaloes are particularly aggressive and protective when they have calves. Any perceived threat to their offspring is met with fierce resistance, making it even more perilous for predators targeting young buffaloes.

A fully grown African buffalo can weigh up to 1,000 kilograms (2,200 lbs) or more. Their broad, curved horns, which can grow over a meter in length, combined with their sheer bulk and power, make them a formidable adversary.

Among the «Big Five» game animals in Africa—which includes the lion, leopard, rhinoceros, elephant, and buffalo—it’s often said that more hunters have been killed by buffaloes than by any of the other animals. This is due to the buffalo’s aggressive nature when wounded or threatened.

Unlike other herbivores that might flee at the first sign of a threat, buffaloes often stand their ground. Their first instinct is often to investigate a potential threat rather than to run from it.

The horns of the African buffalo are a signature feature and serve multiple functions.

One of the most obvious purposes of the buffalo’s horns is for defense. They use them effectively to fend off predators, rival buffaloes during territorial disputes, and any other perceived threats.

Within buffalo herds, horn size and the broadness of the boss can be indicative of a male’s age and dominance. Larger horns with a more developed boss often belong to older, more dominant males.

The «boss» is the central part of the horns, at the base, where they fuse together on the buffalo’s forehead. In males, the boss is thick, broad, and often appears as a solid shield of bone. This dense structure provides protection during head-to-head clashes with rivals. As males age, their bosses become harder and more pronounced.

The horns, especially the boss, contain a network of blood vessels. When the buffalo is overheated, blood can circulate through these vessels, helping to dissipate heat. As the warm blood flows through the horn structure and is exposed to the cooler external environment, it cools down before returning to the body. This acts as a thermoregulation mechanism.

While both male and female African buffaloes have horns, there are noticeable differences between them. Males typically have larger, more curved horns with a well-defined boss, while females have smaller horns that are more slender and lack the pronounced boss characteristic of the males.

The horns of a buffalo continue to grow throughout its life. Buffaloes can often be seen rubbing their horns against trees or the ground. This behavior helps to remove dirt, parasites, and also assists in shaping the horns.

The horns of African buffaloes are sometimes used by local communities for crafting tools, musical instruments, and ornaments. However, hunting for trophies, including horns, has raised conservation and ethical concerns in some regions.

In essence, the horns of the African buffalo are multifunctional, serving vital roles in defense, thermoregulation, social hierarchy, and even culture. They’re an integral aspect of the buffalo’s biology and behavior.

African buffaloes act as reservoirs for several diseases, and their interaction with both wild ecosystems and domesticated animals can lead to significant health and economic concerns.

African buffaloes are natural reservoirs for the foot-and-mouth disease virus. While they can carry and shed the virus, they often don’t show clinical signs of the disease themselves.

When domesticated animals, such as cattle, come into contact with infected buffaloes or areas where they’ve grazed, there’s a risk of transmission. FMD can severely impact livestock industries due to decreased meat and milk production and trade restrictions.

Caused by Mycobacterium bovis, bovine tuberculosis can affect a range of animals including buffaloes, cattle, and even some wildlife species.

African buffaloes can harbor the bacteria without showing signs of the disease for a long time. When they come into contact with cattle or other wildlife, there’s potential for transmission.

African buffaloes are not direct carriers of the sleeping sickness, but they play a role in maintaining the population of tsetse flies, which are the vectors for the disease.

Tsetse flies feed on the blood of various animals, including buffaloes. While feeding, the flies can pick up and transmit the trypanosome parasites that cause African sleeping sickness (Human African Trypanosomiasis) in humans and Nagana in cattle.

Buffaloes and other wildlife serve as a reservoir for these parasites, making control of the disease complex.

Diseases like FMD and BTB can result in significant economic losses for countries due to reduced livestock productivity and trade bans.

Sleeping sickness, while not directly transmitted by buffaloes, remains a significant health concern in parts of Africa, with buffaloes playing a role in the maintenance of its vector.

Efforts to control these diseases in livestock can sometimes lead to unintended consequences for wildlife. For instance, culling or relocating buffaloes to reduce disease transmission might impact the ecological balance of an area.

Integrated approaches, which consider both livestock health and wildlife conservation, are essential for sustainable disease management.

The role of African buffaloes in disease ecology underscores the interconnectedness of wildlife, livestock, and human health. This concept, often referred to as «One Health,» recognizes that the health and well-being of all these groups are interlinked and highlights the need for collaborative approaches to address shared health challenges.

Buffaloes have a range of vocalizations, from grunts and bellows to croaking calls, which they use for communication within the herd and to establish dominance.

Grunts: These are short and low-pitched sounds made by buffaloes, often during casual interactions within the herd or when they are on the move. Calves frequently grunt to maintain contact with their mothers, especially in dense vegetation.

Bellows: A deep, resonant call that can be heard from a distance. It’s often associated with distress or as a rallying call. For instance, if a buffalo is separated from the herd or senses a threat, it might bellow to alert others or to gather the herd.

Croaking Calls: This sound is quite unique and resembles a frog’s croak. It’s often associated with dominance and mating displays, typically emitted by bulls during confrontations or to establish hierarchy.

Moos: Similar to cattle, buffaloes also produce mooing sounds, especially calves when they are trying to communicate with their mothers or when they feel lost.

Snorts and Growls: When alarmed or sensing danger, buffaloes might emit sharp snorts. Growls, on the other hand, can indicate irritation or a warning, especially during intra-herd disputes.

Communication with Calves: Mother buffaloes have specific calls they use to communicate with their calves. This helps in ensuring that the calf stays close and can find its mother among the many buffaloes in a large herd.

Social Cohesion: Vocalizations play a vital role in maintaining the social structure and cohesion of buffalo herds. Through various sounds, they can alert each other of dangers, locate separated members, and establish social hierarchies.

Threat Displays: Apart from vocal sounds, buffaloes also use non-vocal auditory displays to show dominance or signal a threat. This includes behaviors like horn clashing or hoof stamping.

Understanding these vocalizations gives insights into the complex social behaviors and interactions within buffalo herds. Their ability to communicate in various ways is a testament to their adaptability and survival in the diverse and often challenging environments of Africa.
