The Great migration is one of the world’s most spectacular wildlife events.
Often referred to as 'The Greatest Show on Earth' the Migration is a movement of approximately 1.5 million wildebeest and zebra throughout the Serengeti and Masai Mara ecosystems.
The Migration is dependant on rain and the animals move back and forth following the rains.
The water supply, be it rain for the new grass or standing water to drink is never in the same place and is quite often spread across different areas of the Serengeti.
Therefore, the animals split.
They are animals and they cannot be predicted!
When wildebeest number 1 thinks its best to go to the Western Corridor, half a million may follow him.
Number 50001 however may well think it will be best elsewhere and take the remaining numbers with him.
