Around 400,000 plains zebras follow the Great Migration alongside 1.5 million wildebeest through the vast Serengeti-Mara ecosystem. Zebras graze the tallest grasses first, leading the herds year-round — from the Ndutu calving plains (January-March) to the dramatic Mara River crossings (July-September). Ngorongoro Crater holds a resident population of around 7,000 zebras in its self-contained caldera ecosystem, independent of the migration, making sightings guaranteed in any month.
