Annually, over a million wildebeest, along with hundreds of thousands of zebras and gazelles, embark on a circular journey across the plains of East Africa. This event, known as the Great Wildebeest Migration, spans the Serengeti in Tanzania and the Masai Mara in Kenya, driven by the search for fresh grazing and water. The trek is timed with the seasons, experiencing distinct wet and dry periods. This epic undertaking isn’t just a feast for the eyes; it’s a battle for survival. The migrating herds must navigate a landscape teeming with dangers. Lions stalk from the tall grasses, cheetahs explode in bursts of speed, hyenas hunt in cackling packs, African wild dogs pursue with relentless stamina and crocodiles lie in wait in river crossings. The ability of the wildebeest to complete the migration hinges on a combination of herd size, heightened senses, their cooperative behaviour and the vulnerabilities of the very predators that seek to eliminate them. Strength in Numbers: Wildebeest Herd Size as Predator Defence One of the most important defences the wildebeest possesses is its sheer numbers. During the migration, wildebeest congregate in massive herds, sometimes numbering in the tens of thousands. This creates what’s known as the “dilution effect.” The larger the group, the lower the statistical probability that any single wildebeest will become a predator’s target. When faced with a vast expanse of potential prey, a predator must select one individual to pursue. This is when the “confusion effect” becomes apparent. The overwhelming mass of movement makes it hard for predators to focus. Dazzled by the chaos, it’s more difficult for predators to single out a weak or isolated animal and maintain a successful chase. The physical impact of a stampede can deter even the most formidable hunters. A wall of hooves pounding the ground can inflict serious injuries, dissuading predators from getting too close. Research on ungulate populations has repeatedly shown a correlation between herd size and decreased individual predation risk, though specific data for wildebeest during the migration is challenging to collect. The principle remains: the wildebeest’s herd size offers a degree of protection not available to solitary animals. Keen Senses: Wildebeest Hearing, Sight and Smell – Essential for Survival Beyond their numbers, wildebeest possess a set of finely tuned senses that aid in predator detection. Their eyesight is adapted for life on the open plains. With a wide field of view, they can scan the horizon for approaching danger. Wildebeest are particularly adept at detecting movement, allowing them to spot predators lurking in tall grass or approaching from a distance. Complementing their vision is exceptional hearing. They can pick up on subtle sounds that might indicate the presence of danger – the snap of a twig, the rustle of leaves or the distant call of a predator. Their sense of smell also contributes to their survival. Wildebeest can detect the scent of predators carried on the wind from a long distance and potentially recognise danger signals communicated through scent by other wildebeest in the herd. Working in tandem, these senses give wildebeest an early warning system. A flick of an ear, a raised head or a shift in body posture can quickly alert the entire herd to a potential threat, giving them precious seconds to react and escape. Working Together: Wildebeest Cooperative Behaviour During Migration Wildebeest survival is not just an individual endeavour; it’s a group effort. Cooperative behaviour plays a key role in their ability to navigate the dangers of the migration. One of the most evident examples is their use of alarm calls. When a wildebeest spots a predator, it emits a loud, distinctive call that warns the entire herd. Even young wildebeest, instinctively recognise the sound and react immediately, bunching together for protection or running to join their mothers. A collective consciousness emerges as many wildebeest take turns watching for danger, creating an environment of group vigilance. While some members graze, others remain alert, scanning the horizon. This shared responsibility increases the chance of early predator detection. Experienced individuals often lead the herd. These seasoned travellers can anticipate danger based on past experiences, guiding the herd along safer routes and avoiding potential ambush locations. In some situations, wildebeest will directly confront smaller predators. If a jackal or hyena poses a threat to the herd, particularly to the young, several adults may band together, charging toward the intruder and driving it away with their combined strength and aggression. Predator Vulnerabilities: How Wildebeest Exploit Weaknesses Predators, despite their power, have weaknesses that wildebeest exploit. Wildebeest stamina can sometimes outlast predator bursts of speed. Predators also often focus on the injured or weak, diverting attention from the rest of the herd. River crossings, with their dangers of drowning, create risks for predators and prey alike. While young wildebeest are often targets, their mothers fiercely defend them and groups of adults can stand their ground against smaller threats. Wildebeest adapt to exploit any weakness of their hunter. A Delicate Balance in the African Plains Wildebeest survival during the Great Migration is a result of many factors working together. Their herd size, heightened senses, cooperative behaviours and exploitation of predator weaknesses all contribute to their persistence. But this incredible journey is one of constant struggle. Many wildebeest don’t make it, falling prey to predators, disease or exhaustion. The migration is important to the African ecosystem. Grazing wildebeest shape the vegetation and their presence supports a wide variety of predators and scavengers. It is a beautiful and yet tragic event, showcasing the delicate balance between life and death on the African plains.
