Every Friday, we choose our favorite photo of the week from our Wildlife Photo of the Day website.

This week we chose a sleepy fox in Yellowstone National Park.

Photographer Tad Sattler and his son were making their way out of the park, after spending 5 days there, when they came upon this red fox sleeping on a cliffside opposite a ravine.
