| The White-sided Jackrabbit strongly prefers level ground to hills, and does not require shrubs for cover, but uses clumps or dense stands of grass instead. Grass also makes up more than 99 percent of its diet. Livestock grazing of native grasses most likely has contributed to the decline of this species. White-sided Jackrabbits tend to form male-female pairs, and the male will defend the pair from other males. The breeding season of the White-sided Jackrabbit runs from mid-April to mid-August. There are one to four offspring (usually two) in a litter. Predators include eagles, hawks, owls, foxes, and coyotes.
