Doug Smith, the leader of Yellowstone's wolf project, gets to witness some interesting things when he surveys Yellowstone in the course of his research. A recent photo he took while tracking wolves captures an amazing scene: a grizzly bear standing over a fresh bison carcass. I asked Doug about the photo and the origin of the bear's bison meal, as grizzlies are known for stealing kills from wolf packs. His guess is that the "bear found and controlled the dead bison from the start. It's not really touched yet and it's very recent activity so the wolves likely got nothing." From the look on the bear's face, he has no intention of sharing his meal!
