The endless plains of east Africa are the setting for the world's greatest wildlife spectacle - the 1.5 million animal ungulate (wildebeest) migration. From the vast Serengeti plains to the champagne colored hills of Kenya's Masai Mara over 1.4 million wildebeest and 200,000 zebra and gazelle, relentlessly tracked by Africa's great predators, migrate in a clockwise fashion over 1,800 miles each year in search of rain ripened grass.
There is no real beginning or end to a wildebeest's journey. Its life is an endless pilgrimage, a constant search for food and water. The only beginning is at the moment of birth. An estimated 400,000 wildebeest calves are born during a six week period early each year - usually between late January and mid-March.
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.
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.
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.
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.
November
The arrival of the short rains call the migration southward. 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.
