The great Serengeti wildebeest migration is the movement of vast numbers of the Serengeti's wildebeest, accompanied by large numbers of zebra, and smaller numbers of Grant's gazelle, Thomson's gazelle, eland and impala. These move in an annual pattern which is fairly predictable. They migrate throughout the year, constantly seeking fresh grazing and, it's now thought, better quality water.
The precise timing of the Serengeti wildebeest migration is entirely dependent upon the rainfall patterns each year – here we explain how the broad pattern works.
