Across the great plains of Africa

This time of year, from late January to early March, babies arrive on the Serengeti. At the height of the wildebeest calving season, thousands of calves are born every day. Moments after birth, these youngsters can walk, and in just a few days, they'll be able to run fast enough to keep up with the herd. That's a good thing. Calving season isn't just a draw for safari tourists wanting a front row seat at the start of the circle of life, but also for predators like lions, cheetahs, and hyenas on the hunt for easy prey.

As spring edges closer to summer, the grasslands in the Serengeti National Park will begin to dry out. Following in the hoofprints of some 750,000 zebras, about 1.5 million wildebeests, young and old, will start their trek north in what's considered the largest land mammal migration on Earth. Safe travels!
