A hulking grizzly bear has found online stardom after he was caught groggily emerging from hibernation on camera. Canadian ranger Nicole Gagnon filmed the end of Boo’s hibernation on her phone, a moment she said she had been waiting to document for eight years. It has since been viewed over 100,000 times on Twitter. Boo, 18, draws thousands of tourists every year to his 20-acre enclosure near the town of Golden, Canada
