Special Mention Banff Mountain Photography Competition
Over several trips to Alaska's Denali National Park, Colorado-based photographer Michael Mauro has witnessed many predator-prey interactions.
Mauro shot this image after coming upon a grizzly and her two cubs feeding on the carcass of a caribou killed by wolves.
"Just as their feeding frenzy was about to end, I looked down the river bar and spotted a very large solo bear coming towards the kill. Taking notice, the sow proceeded to pick up the head and began shaking it violently from side to side in what I assumed was a display for the approaching bear," Mauro said in a statement.
