As autumn draws to a close, male polar bears converge at the coast for the “big freeze.” This annual event is hotly anticipated after a long summer spent starving on land. Now with the landscape’s imminent transformation, the bears will finally be able to reach their seal prey out at sea. While waiting, these thousand-pound animals turn to fighting each other. But these epic acts of aggression are not what you think. @bertiegregory’s close-up filming allows us to explore the fascinating and sometimes even tender rituals between males, while also showing the incredible adaptations that have allowed them to thrive in this harsh environment. When on foot with the world’s biggest land predator, you must always be on your guard. Bertie uses expert help with some surprising tactics to avoid becoming a hungry male’s next dinner.
