Photos: Annual wildebeest migration begins in Africa

Wildebeests run across a sandy riverbed of the Sand River as they arrive into Kenya's Maasai Mara National Reserve from Tanzania's Serengeti National Park during the start of the annual migration.

Initial herds of Wildebeest and Zebra arrive at the Sand River. The wildebeest migration is one of the “seven new wonders of the world” in which over two million head of mainly wildebeest and zebra migrate from the Serengeti National Park in Tanzania to the greener pastures of the Masai Mara National Reserve in Kenya during July through to October.
