Short-faced bear

A grizzly bear (the black dot in the middle of the photo) walking near the treeline in Yellowstone's Hayden Valley. The quiet of my evening wildlife watching was suddenly broken by a thick Boston accent. "Oh my gawd! Look! It's a grizz! That's the last animal I needed to see! It's a grizz!" He was right.

It was not very close, being little more than a dot moving along the distant treeline, but through the zoom lens of my camera it was just possible to make out the hump that distinguishes black bears from grizzly bears…
