— Get to know some of the mammals that call Yellowstone home

Bison

Bison can weigh up to 2,000 pounds and are herbivores (食草动物). Despite their size, they are very mobile and can run up to 30 mph and jump up to six feet vertically. In1902, America’s wild bison had decreased to only two dozen due to overhunting. Conservation efforts increased the Yellowstone bison population to 4,800 in 2023. See them in Hayden, Lamar and Pelican valleys.

Gray Wolf

Gray wolves had gone extinct in Yellowstone until 14 were reintroduced in 1995. Today, approximately 108 wolves live here. These social animals live in groups and can be gray, white or black. They hunt elk, deer and bison near dawn and dusk thanks to their excellent night vision. For your best chance of seeing them, head to Lamar or Hayden valleys or Blacktail Deer Plateau in the early morning.

Elk

Up to 20,000 elk summer in Yellowstone, but most move to lower elevations in the winter months. Elk are a large member of the deer family and can be identified by their size and white rumps. Mating season, known as“ the rut”, occurs each fall when male elk fight with each other for females. It’s characterized by their haunting bugling sound. In the summer, see them in Cascade Meadows, Madison Canyon and Lamar Valley.
