The sighting of a Grizzly bear with ravens and/or magpies persistently hanging out nearby, is often an indication that the Grizzly has a source of food it is guarding. This scene is in Yellowstone National Park, with beautiful Hayden valley as the backdrop. Yellowstone National Park, thankfully has a healthy population of the endangered Grizzly bear and it is always a thrill to see one in the wild, but at a distance, for the protection of the person and the Bear.
