Nature Clash: Encounters Of Bears And Wolvesat 7 pm
What happens when two great predators come face to face in Yellowstone? The grizzly and the wolf — they couldn’t be more different. The bear is a loner, ranging far and wide in search of a rich variety of resources. The wolf hunts to survive and finds its strength in speed and teamwork. Their strategies have taken them to the very top of Yellowstone, and it’s no simple matter when they meet. In every encounter, the opposition must be measured, strengths must be tested, and risks must be carefully weighed. Each time, one of them will have a tactical advantage — but which one, and when? What emerges as each remarkable scene unfolds, is the keen awareness that runs through all of Yellowstone. Elk and eagle, coyote and raven, otter and owl, every creature must assess, decide, and act — to fight or to flee? It’s all in knowing your own strengths and limitations in the heat of the moment in Yellowstone.
