The Great Migration
Every year around 1.4 million wildebeest and 200,000 zebra clock up 3,000 kilometres following rain-fed grass from the Serengeti plains of Tanzania to the pastures of Kenya's Masai Mara.
These images show the herds gathered at the Mara and Talek Rivers and the mad rush known as 'the crossing.'
Crossings are most likely from late August through September.
The Mad Rush
The herds of wildebeest and zebra bunch up at the river bank and often surge to and fro for hours before attempting a crossing.
Here a single animal decides to go and the rush begins.
Herd Instincts Take Over
Once going, it seems nothing will stop the momentum. Caution is thrown to the wind as the wildebeest leap from the river banks.
Getting Out a Challenge
Planning seems to be not a strong suite for wildebeest. River exits are often less than elegant and many injuries such as broken legs occur in the rush and crush.
Well Fed Crocodiles
The Nile crocodiles grow fat during the crossing season.
The Graveyard
Bodies of wildebeest litter the river banks.
Vultures Clean Up
White-backed vultures cleaning up wildebeest carcasses on the river banks.
