Kenya has considerable land area devoted to wildlife habitats, including the Masai Mara, where Blue Wildebeest and other bovids participate in a large scale annual migration. Up to 250,000[citation needed] blue wildebeest perish each year in the long and arduous movement to find forage in the dry season.[citation needed] The "Big Five" animals of Africa can be found in Kenya and in the Masai Mara in particular: the lion, leopard, buffalo, rhinoceros and elephant. A significant population of other wild animals, reptiles and birds can be found in the national parks and game reserves in the country. The annual animal migration – especially migration of the wildebeest – occurs between June and September with millions of animals taking part.
