Wildebeest
On the African Savannah occurs a massive wildebeest migration. This is when millions of wildebeest, zebras, and other animals traverse the savannah to find new land to graze and eat. During the rainy season, wildebeest give birth to their caves. Then, typically, the migration begins in the Serengeti National Park of Tanzania as the dry season approaches. Like the other animals, they have to battle the elements of weather, predators, and river crossings that they might not survive.
Predators include lions, hyenas, leopards, and cheetahs, who wait for the wildebeest to cross their path. They keep an eye out for the weakest link. Crocodiles also wait to snatch unsuspecting prey. According to Science, “The wildebeest migration is the world’s most massive animal movement: 1.2 million animals cross the savanna in an 1800-kilometer circuit between Kenya and Tanzania as they follow the rains. They consume more than 4500 tons of grass every day and deposit heaps of dung, transforming the landscapes they cross.” Every single process in the ecosystem is affected. The wildebeest migration is one of the “Seven Natural Wonders of the World” because of the migration’s sheer size (Asilia Africa).
