The great migration of wildebeest is one of the world's most dramatic natural wonders: Every year in Africa, more than 1.5 million wildebeest migrate across the Serengeti in Tanzania and into the Masai Mara in Kenya in search of fresh grazing pastures.
Photographers and brothers Will and Matt Burrard-Lucas journeyed to see the migration first-hand, recording the huge effort in stunning photos, time-lapse sequences, and a video.
It's the largest mass-movement of land mammals on the planet—and the thunderous charge is nowhere more hectic than at the Mara river, where the thousands and thousands of animals are forced to converge in order to cross to the other side.
