Summer and winter pelages of white-tailed jackrabbit are drastically different. In summer, the overall appearance is grizzled dark grayish with overtones of pinkish buff, blending lighter on the sides. In winter, it is the color of dirty snow, shading lighter on the sides.
In Oregon, the white-tailed jackrabbit occurs east and south of a line connecting Rufus, Maupin and Antelope, John Day, Juntura, Fields, Fort Rock, and Fort Klamath and Klamath Falls. It is associated with bunchgrass habitats.
