Two zebras graze the grassland at dusk in Kenya's Masai Mara National Reserve. Every year, the reserve's 200,000 zebras join 1.5 million wildebeests in an epic migration, following the rain more than 300 miles (480 kilometers) from Tanzania into Kenya in the dry season, then south again to foal on the storm-soaked Serengeti Plain.
