Bison Ecology - Yellowstone National Park (U.S. National Park Service)

The bison breeding season (or rut) has begun, and you can actually see the fur fly! Males will fight for dominance and the chance to breed females. During the rut, males may go head-to-head in aggressive forms of bison socialization: head-butting, shoving, sizing up, and long stares. Ultimately, it will be the females who choose their mates. 📸 Video credit: Mallory Beckman, Crane Trust Range Technician | Crane Trust
