The high-stakes autumn feast that fuels a grizzly's survival
In short: Watch how heavy autumn rains trigger a massive migration of salmon, creating a critical window of opportunity for a group of hungry grizzlies. This footage captures a pivotal moment in the cycle of survival.
During the autumn season, heavy rains cause rivers to overflow, allowing salmon to travel upstream to their original birthing places. This migration provides a vital feast for grizzlies, who must stock up on calories before the onset of winter.
The video is part of a series exploring how seasonal transformations dictate the challenges of wildlife. While summer offers abundance, autumn serves as a final, desperate window for animals to breed, grow, and accumulate the energy needed to endure the dramatic conditions of the coming winter.
