The Great Migration is an epic, annual journey of around 1.5 million wildebeest, accompanied by zebras and gazelles, as they travel in a circular route of roughly 1,800 miles across the Serengeti-Mara ecosystem in Tanzania and Kenya. Driven by the search for fresh grazing and water, the herds face numerous challenges, including the treacherous crossings of the Grumeti and Mara rivers, where crocodiles and powerful currents pose deadly threats. This migration follows the seasonal rains, beginning with calving in southern Serengeti and moving northward through predator-rich territories, culminating in a return to the Serengeti for the next calving season. It’s a vital event for the ecosystem, supporting predator-prey dynamics and sustaining biodiversity in the region.
