Grizzly – A Yellowstone Story | Free Documentary Nature

An intimate nature documentary narrated by Susan Sarandon that explores the dramatic survival stories of grizzly bears within Yellowstone National Park. Shot over three years, the narrative follows Mary, a dedicated mother struggling to protect her vulnerable cubs near human campgrounds, and Thumper, a young three-year-old male fighting for territory and food carcasses against wolves, black bears, and larger rivals (0:28). The content highlights the heavy pressures of seasonal hibernation preparation and underscores how human conflict remains the most critical threat to the species' long-term survival in the American West (1:52).
