masai mara wildebeest migration 2013

The Migration of Wildebeest.
The Wildebeest arrive at the Mara River around July and cross over onto the Masai Mara plains. The wildebeest remain here until October, when they return to Tanzania. Gazetted in 1961, the Reserve is located west of the Rift Valley and is a natural extension of the Serengeti plains. The Mara River, the reserve's backbone, traverses north to south. This river course is the natural barrier crossed every year by the large herds of wildebeest and zebra during their migration.

Masai Mara Wildlife Migration

May & June
In late May, the herds leave the Western Corridor for the northern Serengeti plains and woodlands. The fresh, tender and mineral-rich pastures on the other side of the humans' border, in Masai Mara, are the irresistible bait for the animals to finally invade the Kenyan reserve, an event which usually starts in late June to early July. The troops coming from the south meet here another migratory contingent: the resident wildebeest herds of the Mara region. These animals reside in the Loita Plains and Hills, northeast of the Mara, until the dry season brings the tougher days and it is time to seek the evergreen Mara basin.

July to October
Throughout the month of July, the herds cross the Sand River, a mostly dry tributary of the Mara which roughly

follows the boundary line between Kenya and Tanzania. The parade takes the eastern sector of Masai Mara, surrounding the Keekorok Lodge area. The trek follows westward, leading the herds to face the major challenge along their quest: crossing the Mara river and frequently also its tributary, the Talek. By then, the rains at the Mau Escarpment, where the Mara rises, have fed the stream to its highest levels.

The steep banks are populated with trunk-looking basking crocodiles that seem almost to be expecting their annual banquet. The operation of fording the river is the most delicate along the migration, and as such seems to plunge the gnus in a state of anxiety that only relieves when the whole herd has crossed. The trekkers walk along the left (eastern) bank of the Mara looking for a suitable point to cross. There are plenty of preferred crossings along the course, which are easily identifiable by the lack of vegetation, the depressed slopes and the deep grooves carved by the animals' hooves. These are the most secure places to ford the river, those that ensure a minimal mortality. Nonetheless, the apparent programming of the whole process sometimes seems to collapse, and the nervous herds occasionally choose places where the banks are too steep and many of the animals break their legs down the cliff or fall flat into the waters. The herds gather at the suitable points and wander around nervously, their grunts sounding loud in the air. Eventually, one animal takes the lead and approaches the rim, scanning the opposite edge to analyze if any danger awaits after the crossing. When it finally dives into the stream, this seems to haul the rest of the herd. More animals follow in a single line across the river, while the lagged ones throw themselves towards the stream until the rearguard pushes the troops to a frantic race that ends up with some animals trampled to death, lying aside the course. Along the boreal summer, the crossings repeat over and over, and the survivors graze peacefully on the Mara Triangle grasslands unless disturbed by the early-morning and late-evening hunts of lion and cheetah, the latter preying on the calves.

By October, the rains are heading south back to the Serengeti. This is when the pace of the march reverses, bringing the herds to face once more the quest for the southern grasslands. The rite of fording the river is again part of nature's call. In the last days of October, the migration heads towards the vast plains of the southern Serengeti, where a new generation of calves will be born to start the cycle of life all over again. Normally the route is down the eastern side and the pace is fast. Quite often a million animals can be seen stretched out.

The Migratory Path

DECEMBER, JANUARY, FEBRUARY, MARCH The Serengeti National Park / Ngorongoro Conservation Area is arguably the most impressive wildlife sanctuary in the world. During the months December through March the seemingly unending plains of the southern Serengeti and the Conservation Area are inhabited by enormous herds of wildebeest and zebra. The great herds graze on rain ripened grass.

In the calving season (late January through mid March) the herds concentrate at the Ndutu and Salei plains (Southern Serengeti / Ngorongoro Conservation Area) attracting the attention of predators like lion, cheetah and hyena.

During this period the migration is best observed from Ndutu Safari Lodge, Kusini Camp or any of several private tented camps used by mobile safaris such as our "Classic Tanzanian Tented Safari". These include campsites in the Ndutu/Naabi area.

APRIL, MAY During the months April and May the depleted plains are unable to sustain the endless herds. The migration, sweeping west and north, moves from the short grass plains of the southern Serengeti / Ngorongoro Conservation Area to the long grass plains and woodland of the Serengeti�s western Corridor, almost to Lake Victoria.

This period is during the long rains and is considered off season for wildlife viewing in east Africa as roads are often impassable. Ndutu Safari Lodge, Kusini Camp and the Serengeti Serena Lodge are fine for wildlife viewing during this time. So are campsites in the Ndutu/Naabi area.

JUNE By the end of May the wildebeest have exhausted the Western Corridor�s best pastures and the herds must move further north. Entering the Lamai Wedge and the Mara Triangle breeding occurs May through June.

This is a transitional period between the rains and the dry season. The Serengeti Serena is a central, easily accessible lodge for viewing the migration at this time. Grumeti River Camp, Migration Camp and Kirawira Camp are also options. Seronera and Moru area campsites are best.

JULY, AUGUST, SEPTEMBER, OCTOBER By July the countless herds have amassed along the swollen Mara River - a final barrier from the short sweet grasses of the Masai Mara. Sometimes the crossing place they have chosen is shallow allowing the majority of animals to pass safely. In other areas the waters boil with drowning wildebeest and slashing crocodiles.

Between July and October the wildebeest reside in the Mara. We recommend Governor's Il Moran Tented Camp as the leading safari camp in the Masai Mara. Other tented camps include Governor's Main Camp, Little Governor�s Camp, Bataluer Camp, and Mara River Camp. Tanzanian lodges recommended during this time include Kirawira Tented, Migration Camp, and Grumeti River Camp. Kirawira and Moru area campsites are best.

NOVEMBER The arrival of the short rains call the migration southward. During the short rains of November the wildebeest migration is best viewed from either Lobo Wildlife Lodge or Klein�s Camp. Campsites in the Lobo area are best.

As November ends the migration is making its way back to the southern Serengeti and early in the year they once again give birth. The circle of life is complete.

Note - the migration is a natural event and the timing varies month by month; year by year.
