The need for fresh grass forces them to spend their lives in migration. But these animals love to graze leisurely, so they never haste and rarely move on more than 3 km per day. That slow pace is typical for a "nomadic migration."

A good viewing spot for American bison is the Lamar Valley in Yellowstone National Park. It's possible to track grazing mammals via wildlife safaris.
