Wildlife photography of a Red Fox curled in sleep on sloping snow in bright sun

In the bright Winter sunshine of Yellowstone National Park, a Red Fox naps curled on unbroken snow in the warming light of late afternoon. As warming sunshine wanes in the Winter, the Red Fox’s wonderfully full tail becomes a muffler, keeping their face warm and protected while curled up against the cold. When wolves were expatriated from the Yellowstone region, coyotes proliferated and reduced the fox population. But the reintroduction of wolves into the ecosystem brought coyotes back into balance, creating equilibrium and allowing the foxes to recover.
