Migration means a regular journey that animals make - usually to follow rain, fresh grass, or water. The animals in and around Boma travel huge distances between the wet and dry seasons. Scientists who flew over the area counted more than a million animals moving at once - which is even more remarkable than the famous wildebeest migration in East Africa.
The white-eared kob is the star of Boma. It is a medium-sized, reddish-brown antelope with round, white-edged ears that flash in the sunlight as the herd runs. Males have curved horns and stand proudly on flat-topped termite mounds to show off for females. Their hooves pound the dry earth with a sound like distant thunder.
Boma is also home to elephants, buffalos, lions, leopards, and giraffes. The park has been protected for a long time, which means the animals have safe places to raise their young. Baby elephants stay close to their mothers' legs, and young antelopes can run within hours of being born.
The park gets its name from the Boma Plateau - a high grassy plateau where the air is cooler and mist rolls in during the wet season. From the plateau, on a clear day, you can see all the way across the flat plains where the great herds gather.
