The white-tailed jackrabbit is a large hare of North America with long legs and ears. It has a white tail and the ability to change the color of its fur depending on the season.
The white-tailed jackrabbit differs from other hares by its white tail at any time of the year and by changing the color of its fur in winter. It serves as food for coyotes, eagles and other predators and helps maintain the balance of vegetation in the prairies.
