When we launched MasaiMara.ke, we wanted to stand out in the way we present information in a way that’s most helpful, comprehensive, and super informative getting reliable info from peer-reviewed studies on Mara Ecosystem’s Great Migration. The more we took time to organize the site structure, we knew we needed to break it down so our readers will find our resource easy to follow and comprehensive.
This comprehensive guide we have named Masai Mara Great Migration 101 guide is broken down into sections linking out to different posts on this website. In total, there are 7 key Great Migration topics.
The Great Migration in the Masai Mara, part of the larger Serengeti-Mara ecosystem, has long fascinated both scientists and nature enthusiasts. Traditionally, biologists believed that the grazing patterns of the migration followed a sequence where zebras, followed by wildebeest, and then Thomson’s gazelles, each cleared the way for the next species, facilitating their access to preferred plants. However, recent research has upended this understanding, providing new insights into the competitive dynamics driving this mass migration.
A study led by Professor T. Michael Anderson from Wake Forest University, published in the journal Science in February 2024, presents a groundbreaking view of these migration patterns. The research, titled “Interplay of competition and facilitation in grazing succession by migrant Serengeti herbivores,” reveals that competition, rather than facilitation, is a key force in the grazing succession. The study is the most comprehensive to date, combining data from camera traps, GPS collars, diet analysis, and satellite tracking to understand the interaction between wildebeest and zebras as they traverse the plains.
Anderson’s research team found that the wildebeest, whose population exceeds 1.3 million, play a dominant role in this dynamic. Their grazing behavior exerts significant pressure on the grasslands, effectively pushing the roughly 200,000-strong zebra population ahead of them in a race to consume the most nutrient-rich grasses.
This “push-pull” hypothesis suggests that the zebra must move ahead of the wildebeest to meet their substantial energy needs, as lingering behind would leave them with insufficient forage. Contrary to earlier beliefs, the zebras are not simply paving the way for the wildebeest; instead, they are driven by the necessity to outcompete them for food.
Moreover, while competition dominates the interactions between wildebeest and zebra, facilitation still plays a role in the broader migration ecosystem. After the larger grazers move on, the Thomson’s gazelles benefit from the access to flowering plants and shrubs that were previously hidden under the tall grasses, which the wildebeest and zebras have grazed down.
This new understanding of the Great Migration has far-reaching implications. As Anderson notes, the Serengeti-Mara ecosystem, which still functions as it did hundreds of thousands of years ago, offers vital lessons for managing and restoring grasslands globally. With the added pressures of climate change and human encroachment, these insights are crucial for informing conservation strategies that aim to preserve the delicate balance of these ecosystems.
Funded by organizations such as the National Geographic Society and the National Science Foundation, this research underscores the complexity of the Great Migration and challenges long-held assumptions about the interspecies relationships that drive it. As the world continues to grapple with environmental changes, studies like this provide critical knowledge to support the sustainable management of one of the planet’s last great migrations.
The Great Migration is one of the most incredible wildlife spectacles on Earth, involving millions of wildebeest, zebras, and gazelles as they move across the Serengeti in Tanzania to the Masai Mara in Kenya, following the seasonal rains. Here’s a detailed, month-by-month expert guide based on the uploaded maps and provided insights:
January – March: Calving Season (Southern Serengeti)
During this time, the herds are primarily found in the southern Serengeti, where they calve on the nutrient-rich short grassy plains. The soil in this region is high in minerals, which is essential for the health of the wildebeest and their newborn calves. This area has a diverse ecosystem comprising forested areas, marshes, soda lakes, and open plains. Over 500,000 calves are born during this period, attracting predators like lions, cheetahs, and hyenas. It’s a prime time for witnessing predator-prey interactions and new life. The open plains allow for incredible photography opportunities and wildlife sightings.
Highlights:
- Calving: Thousands of young wildebeest are born, providing a dramatic scene for visitors.
- Predators: Expect excellent sightings of lions, cheetahs, and hyenas taking advantage of the vulnerable young calves.
- Birdwatching: Many migratory bird species are present in the southern Serengeti, making it a birdwatcher’s paradise.
April – May: The Movement to Central Serengeti
As the rainy season begins, the herds start moving northwards in splinter groups, traveling through the central Serengeti and the western corridor. This is a great time for more extended game drives with picnic lunches as visitors can follow the herds as they traverse these expansive areas. Central Serengeti offers a fantastic mix of wildlife, including excellent sightings of leopards, lions, and elephants, particularly around the Grumeti River.
Highlights:
- Leopard Sightings: Central Serengeti is renowned for its healthy leopard population.
- Picnic Safaris: A unique opportunity to spend full days out in the bush tracking the splinter herds.
- Varied Wildlife: Lions, elephants, and other big game continue to follow the migration, making it an exciting time for wildlife enthusiasts.
June – July: Grumeti River Crossings and Movement North
By June, many of the splinter herds have congregated in the western Serengeti and are preparing to cross the Grumeti River, where some of the most dramatic scenes of the migration occur. As they move northwest, the herds can often be seen crossing the Grumeti River en route to the northern Serengeti, near the &Beyond Grumeti Serengeti Tented Camp. Depending on the rains, this is the time to witness the perilous river crossings, with crocodiles lying in wait.
Highlights:
- Grumeti River Crossings: One of the most dramatic spectacles, with herds risking their lives to cross the crocodile-infested waters.
- Elephants and Lions: The Grumeti region is home to large populations of elephants and prides of lions, making for an exciting time for game drives.
- Scenic Landscapes: The lushness of the Serengeti during this time offers stunning scenery for photography.
July – October: The Masai Mara and Northern Serengeti
The herds have now reached the northern Serengeti and the Masai Mara. This is the most famous phase of the migration, where over 1.5 million wildebeest cross from Tanzania into Kenya’s Masai Mara, following the rains. The crossings at the Mara River are perhaps the most iconic scenes of the entire migration. The herds move back and forth across the river multiple times, making this a dynamic and unpredictable period.
Highlights:
- Mara River Crossings: The dramatic crossings of the Mara River, where many wildebeest fall prey to waiting crocodiles, is a sight not to be missed.
- Big Cat Sightings: The northern Serengeti and the Masai Mara are renowned for their big cat populations, including lions, leopards, and cheetahs, all in search of prey during this time.
- Best Time for Game Drives: With the abundance of wildlife and the cooler, dry weather, this is one of the best times for game drives and witnessing the sheer scale of the migration.
November – December: The Return South to Serengeti
By November, the herds begin their journey back south towards the Serengeti. The rains have begun again, and the herds move down past Grumeti and the central Serengeti, often breaking into smaller groups. Some herds move through the eastern and western corridors, while others pass through Lobo and the central Serengeti before arriving at the southern plains.
Highlights:
- Scenic Movement: As the herds make their way south, this is a great time to witness the animals spread across the Serengeti in smaller groups, creating a different dynamic from the larger herds seen earlier.
- Lobo Area: This area sees significant herd movement, offering fantastic wildlife viewing opportunities with fewer tourists compared to the busy Mara season.
- Big Cats: Predators continue to follow the herds south, providing excellent opportunities to see lions, cheetahs, and leopards.
Conclusion
The Great Migration is an unparalleled spectacle that changes month by month. From the calving season in January to the dramatic river crossings in July, each phase of the migration offers unique and thrilling wildlife experiences. The unpredictability of the herds’ movements, influenced by the rains, makes each safari during the migration a unique adventure.
