Bears use different techniques to catch Salmon at Brooks Falls. Here's a couple of my favorite.
The "smash-n-grab" demonstrated here by 755 "Lefty" who has taken it to it's extreme.
The "Zen" demonstrated by 480 "Otis". It's not as spectacular as the "smash-n-grab" but it is the most deadly and efficiant.
Here's 18 (Humphrey) successfully employing the "smash-n-grab" along side Otis the one and only "Zen Master".
PS: The bears can be seen live daily here.
