Making a circular migration route of up to 1,000 miles and numbering 1.5 million animals, the wildebeest takes the record for the largest migration on earth. Wildebeests live on African savannas where they feast on wild grasses and other herbaceous plants. After the rainy season ends in May and June, these large African antelope migrate in with hundreds of thousands of other African animals including zebras and gazelles from the Serengeti Plain to the Savannas where food and water is plentiful. Thousands drown and many are eaten by crocodiles when they cross the Mara River during their migration. Due to high reproduction rates, the population of this species is stable.
