The great migration is the largest animal migration on earth starting in Tanzania southern Serengeti and ending in Kenya Masai Mara National Reserve following a clockwise circular migratory pattern. Millions of Wildebeest and Thousands of Zebra, and Gazelle another other herbivores make this journey every year in pursuit of the grassy lower plains of the Masai Mara and escaping the dryer southern plains
During December to March the southen Serengeti plains and Ndutu Area are a birthing ground for Wildebeest. It is this time of year that these plains are covered in lush grasses giving life to over 2 million herbivores.
In mid-February to April, once the calving is complete and the resources of the southern Serengeti dry up, the Great Migration starts taking the animals north west deep into the Serengeti National Park.
The herds start to reach the Grumeti River in July and many wildebeest become victim of the deep waters of the river and the Nile Crocodiles that live here. The herds then continue north crossing Mara River and into the lower grassy plains of the Masai Mara.From October to end of November the herds return to the Southern Serengeti to graze and give birth to their young before the cycle starts over again.
