Mule deer (Odocoileus hemionus), Lava Beds National Monument, 2014.
These mule deer were spotted near Indian Well Cave. Indigenous to western North America, mule deer are easily recognized by their characteristically-large ears that similar in appearance to a mule. In areas where white-tailed deer and mule deer overlap, differentiate the two species by the ears, antler configuration or tail. Mule deer have bifurcated (i.e., forked) antlers while white-tailed deer antlers branch from a single point. Mule deer also have a black-tipped tail while white-tailed deer, perhaps not surprisingly, have white tails.
