200 Kills a Year： The Grizzly Bear’s Obsession With This Rodent

In the harsh landscapes of North America, the difference between life and death for the continent's most feared predators often comes down to a creature weighing less than a pound. From the frozen tundra of Northern Alaska to the scorched Sonora Desert, ground squirrels serve as the primary fuel for grizzlies, foxes, and golden eagles. This documentary follows the high-stakes survival of the Arctic ground squirrel, a biological marvel that can survive with a body temperature below freezing, and the black-tailed prairie dog, whose massive underground colonies support an entire neighborhood of hunters. Watch as a Grizzly bear works for hours to secure a high-protein meal and see how the rare Black-footed Ferret relies entirely on these rodents for its very existence. This is the untold story of the struggle at the bottom of the food chain that keeps the top alive.
