Description

White-tailed Jackrabbits live at a remarkably broad range of elevations, from 40 m to 4,300 m, and where they are in competition with Black-tailed Jackrabbits, they tend to move toward higher elevations. They are slightly larger than black-tails, but seem to be more selective in their dietary choices, putting them at a disadvantage where the two species overlap. White-tailed Jackrabbits prefer grassland habitat, feeding on grasses and green forbs first, and resorting to shrubs during the winter months.They are among the most solitary of hares and usually interact only briefly during the breeding season, when small groups may be seen. A female may produce 1-4 litters, usually of 4 or 5 young, each year.
