White-tailed Jackrabbit

Hare & Jackrabbit

The White-tailed Jackrabbit (Lepus townsendii), also known as the Prairie Hare and the White Jack, is a hare found in western North America. Briefly reputed to have been extirpated, it is now clear from observations, roadkilled specimens and historical records that white-tailed jackrabbits are still extant in Yellowstone National Park.
