The Maasai Mara National Reserve is located in southwest Kenya. Each year African zebras, blue wildebeest (Connochaetes taurinus), Thomson’s gazelle (Eudorcas thomsonii) and other species of antelope participate in what is known as the Great Migration, one of the world’s most spectacular wildlife events. Each year millions of these creatures migrate from the Serengeti National Park in Tanzania across the Mara river to the Maasai Mara National Reserve in Kenya. During the river crossing, a number of African zebras, wildebeests and other antelopes will die by drowning or from attacks by predators, such as the giant Nile crocodile (Crocodylus niloticus) which lives in the river or the African lion (Panthera leo) which roams the river banks.
