In nature, "fast food" has a totally different meaning. These tourists were out enjoying their day at Yellowstone National Park when they spotted a grizzly bear getting ready to chase down a herd of elk. Unfortunately for the grizzly, (but very fortunate for the elk), brown fur isn't really the best camouflage and the herd was able to keep some distance from the bear. For more bear news, let's check in on this backyard in Newtown, Connecticut. Katie was shocked when her cat yelped and hid behind the furniture. When she went to see what was in her backyard, she discovered a young bear cub enjoying her hummingbird feeder. No reports yet on how many hummingbirds have gone hungry in the wake of this theft, but we'll keep you posted.
