Ngorongoro Crater in Northern Tanzania is one of the few places left in Africa where the black rhinoceros is still frequent and can be regularly seen and photographed by the visitor. The crater floor, an area of 100 square miles, is the home of a great variety of game animals. Most numerous are the wildebeest which numbered over 14,000 in the aerial count made by Watson and Turner in 1964. The same count showed more than 5,000 zebra in the crater, 2,000 gazelle, 350 eland, 50 kongoni, 30 hippopotamus, 20 elephant, 25 lion and also waterbuck, mountain reedbuck and steinbuck.
