MAASAI MARA, Kenya (NBC/APTN) - Africa's colorful wildebeest migration has started, and the wildebeests move north from Tanzania's Serengeti to the lush Maasai Mara of Kenya.
This year, the first wildebeests reached the Mara River in late June.
The difference in dates is due to the climate. The drier it is, the earlier the wildebeest move, and the weather in Tanzania is dry this year.
"Because the climate is different in every year. So that is why coming different times to Maasai Mara," said an area guide. "It's not, in Tanzania now. It's dry now. There is no water. There is no grass. That is why they are moving up to Maasai Mara."
It's estimated that 2 million wildebeests make the annual trek each year.
Numerous documentaries have catalogued the long-distance migration, especially the trip across the crocodile-infested Mara River.
Some people use hot air balloons to get an eagle-eye view of the migration. Despite their size, wildebeests can run at as fast as 50 miles an hour.
