Scientists discovered fossil evidence that suggests that wildebeest have been roaming the plains of East Africa for over one million years. They migrate because of their instincts which is in their DNA the same way their body tells them to run when a predator appears out of the grass.

Over 1.5 million animals migrate in an enormous group every year heading northwest to commence a very challenging journey which results to death of many of their family members. It involves crossing the great Grumeti and Mara Rivers, mostly filled with giant Nile crocodiles which feast on many of them. However, there are those which survive, it also results into more life to animals since they migrate in search for greener pastures, they give birth to more off springs on return.

The wildebeest crossing is compared to a swarm intelligence. When the animals start the migration, they look disorganized and makes no sense. Surprisingly, the animals are well organized following a specific route while overcoming the obstacle along the way. They finally arrive in Masai Mara which feels like the promised land filled with new nutrient-rich grasses spread out as far as the horizon. Tired and frightened, they scatter in the vast carpet plains of the Masai Mara and blend with the other animals which they find there.

As November begins, the wildebeest migration begin,s and wildebeests smell the stormy dusty clouds which is a warning of the dry season approaching in the Masai Mara. They now turn around and head back with bravery to the Serengeti through the western Loliondo and Lobo area. They follow the rains on the short-grass plains of the southern Serengeti. By December they start arriving in the southern part of Serengeti so tired and worn out.

During this time, there are quite many expectant mothers, who give birth immediately after they settle. The calves are blessed to drop on the fresh grass and are seen up on their feet in just a few minutes ready to survive on their own. And the cycle begins another year.
