00:00What you're seeing is a brown bear feeding frenzy in Alaska, North America.
00:04The ground is covered in half-eaten salmon carcasses left by brown bears.
00:07Their wasteful eating style attracting numerous nearby birds joining this rare salmon feast.
00:11You're probably wondering, why are so many salmon being wasted,
00:14with each one only getting one bite before being abandoned?
00:16Brown bears can only afford to eat this wastefully during autumn each year.
00:20Autumn is salmon spawning season.
00:22They migrate in massive groups from the ocean back to inland freshwater areas to spawn.
00:26This is when salmon are at their fattest and physically weakest simultaneously.
00:30Swimming through shallow rivers during migration,
00:32they get intercepted by bears that normally struggle to eat their fill of meat.
00:35Since every spawning salmon must pass through here,
00:38they have no choice but to endure relentless bear predation.
00:40This is the most valuable opportunity bears cannot afford to miss.
00:44They selectively target only the largest individuals,
00:47eating specifically the roe and belly,
00:48the parts richest in fat, to accumulate body fat and weight for winter hibernation.
00:52Everything else gets abandoned for nearby birds to share.
00:55Once spawning season ends, bears can't find a single salmon anywhere.
00:59That's exactly why they feast so extravagantly right now.
