This Lone Wolf is a member of one of Yellowstone National Park’s wolf packs. Somehow he got separated from the rest of the pack, so he sat on this snowy ridge and howled for the other member of the pack, waiting for them to respond so he could join them again. If you have ever heard a wolf howl, you will not be surprised that the sound can travel up to 15km away.

Yellowstone National Park is home to 10 different wolf packs, and at least 98 wolves live within the park boundaries (as of January 2016). I was interested to learn that the main cause of death of the wolves within the park was actually other wolves. In the winter the majority of their diet will consist of Elk (over 90%), while in the summer they will consume less elk and more Bison.
