This vast plain is witness to one of nature's great spectacles: the Great Migration of millions of wildebeest, zebra and other grazing animals seeking fresh grass. In addition to wildebeests that dominate in number, are also represented the five species that constitute the Big Five (name given to this set of species by hunters in African safaris during the twentieth century) that are the lion, the leopard, the elephant, the rhinoceros (in low numbers) and the African buffalo (Syncerus caffer). The park is also home to hyenas, cheetahs, zebras, raptors, and many other species.
The Ngorongoro Conservation Area is a place of transit and residence for many migratory animals, mainly mammals. These mammals are mainly represented by ungulates such as black rhino, elephant, Redunca fulvorufula (Mountain Cobe), buffalo, hippopotamus, wildebeest, zebra, eland, Grant's gazelle and gazelle of Thomson but also by the predators who follow them. Thus, the Ngorongoro crater is home to many leopards, jackals, hyenas, African golden cats, cheetahs and the highest concentration of African lions while wild dogs are becoming increasingly rare. There are more than 500 species of birds in the avifauna, the most common of which are the ostrich, the pelican, the pink flamingo and the lesser flamingo, as well as species less known as raptors, parrots (Fischer's inseparable, etc.), passerines and waterbirds (ibis tantalum). , African spoonbill, elegant avocet, gray-headed gull, etc.).
The fauna is particularly diverse and varied because of the great diversity of biotopes. The tropical forest is the territory of the monkeys, whose concentration is one of the highest in the world. Baboons are ubiquitous, sometimes evolving into colonies of several hundred animals. The sparse forest areas and grasslands are home to the traditional East African fauna: herds of buffaloes, giraffes and elephants among others. Among predators, lions have adapted to a very wooded environment and spend most of their time in the trees. The lake is a major sanctuary for birds. The park is home to more than 400 different bird species, including impressive colonies of flamingos and storks
Baobabs, an unusual tree in northern Tanzania, abound in the northern part of the park. The landscape consists mainly of savannah, with many acacias, and becomes more marshy in the South. Note also the presence of many termite mounds, whether they are isolated or leaning against tree trunks-dotted Tarangire is one of the most awe-inspiring landscapes in all of Africa, with an equally impressive population of wildlife, including elephant, zebra, wildebeest and giraffe - along with lion, which are known to occasionally climb trees for relief from the day's heat.
The park is part of the huge ecosystem of the Maasai steppe. During the rainy season, the large herds of herbivores are spread over more than 20 000 km², but as soon as the rains stop, in June, they migrate to the last permanent water point in the region: the river Tarangire. Thus, at the end of winter (August-October), the park is home to a very high concentration of animals, especially elephants; the latter are plagued by significant poaching.
