In Norris Meadow every autumn a small resident herd of elk cows and calvestakes up residence. The grass is thick and nutritious, so they stay until the heavy snows of winter finally drive them away. The elk are attracted to some of the forbs in the meadow too, such as this Canada thistle that the calf had bitten off. Trying to avoid the stickers and break it into smaller pieces, she twisted her head around and up and down hanging onto the thick end with her lips and teeth. Unable to break it apart, she spit it out and moved on to find something more palatable. Location: Yellowstone Park WY. . .
