Feasting on Salmon
Every fall over a hundred Brown Bears descend on Alaska's Brooks River to feast on the largest Sockeye Salmon run in the world. The bears eat up to 40 salmon a day—that's 100 pounds of fish and 100,000 calories.

Because it is one of the first streams in the region where pre-spawned salmon are available to bears, the Brooks River hosts one of the greatest seasonal concentrations of brown bears anywhere on earth.

During late summer and fall, bears usually concentrate in the lower half of the Brooks River. Early in the salmon run, Brooks Falls creates a temporary barrier to migrating salmon providing a fishing spot for bears.

The time of year along with salmon densities and spawning activity dictate when, where, and how bears feed along the river. The prime viewing time for the live cams is September through October. Highlights from the season are featured when live cams are not active.

Bears are eating machines, and their survival is dependent on attaining enough calories over the course of the spring, summer, and fall to sustain them through their denning period.

How do Brown Bears respond to seasonal change? The images and video captured during the fall season are your springboard to research and discovery.
