Serengeti National Park, in northern Tanzania, is known for its massive annual migration of wildebeest and zebra. Seeking new pasture, the herds move north from their breeding grounds in the grassy southern plains. Many cross the marshy western corridor’s crocodile-infested Grumeti River. Others veer northeast to the Lobo Hills, home to black eagles. Black rhinos inhabit the granite outcrops of the Moru Kopjes.

In the vast plains of Serengeti National Park, comprising 1.5 million hectares of Savannah, the annual migration of two million wildebeests plus hundreds of thousands of gazelles and zebras – followed by their predators in their annual migration in search of pasture and water – is one of the most impressive nature spectacles in the world. The biological diversity of the park is very high with at least four globally threatened or endangered animal species: black rhinoceros, elephant, wild dog, and cheetah.
