Interesting read about the connections between declining cutthroat trout, elk calves, and grizzly bear diets.

(I've never seen a photo or heard any stories about bears fishing for trout in Yellowstone, but I think about why this is the case every spring when I watch the spawning trout at Trout Lake, which seem like such incredibly easy pickin's for bears.)
