This moose was pregnant when she was attacked by a pack of wolves two nights before she gave birth. She was torn up pretty bad and stayed in the same place for at least three days. The photographers and onlookers inadvertently kept the wolves away and the Rangers were pretty sure they would both survive. Cool stuff there.
This was a very long shot for my lens, about a 1/4 mile, but I managed to get this wolf stalking buffalo on the plains. I think there are only about 154 wolves in all of Yellowstone. Ultimately, they are not expected to survive because all of the pups keep dying from disease. In a way it makes me not so sad for the moose and buffalo that the wolves take down.
Life in Yellowstone is hard.
