When bison begin to slowly migrate to the Lamar and Hayden valleys, you know it’s rut season in Yellowstone National Park!
What is rut? The rut, or mating, season is the time of year that bison congregate in large herds to compete, socialize, and eventually breed. Male bison (bulls) fight with each other to prove they are strong mates to the females of the herd. Bulls will mate with multiple females over the course of a single season, however female bison (cows) will mate with only one bull. Rut lasts from mid-July through September.
It’s important to remember that during rut, bulls are on high alert and can get aggravated easily! No matter what time of year, always stay further than 25 yards away from all wildlife, and make sure both tires are over the white lines if you pull off the road to view them.
