Mule Deer
(Odocoileus hemionus)

Mule deer are the most commonly seen and photographed large mammal in Zion Canyon. They graze throughout the cooler morning and evening hours in the campgrounds, near the Zion Lodge, and along the Virgin River at the bottom of Zion Canyon. During the heat of the day, they seek shade and den.

The males, or bucks, have elegant and intimidating antlers, which often catch the attention of visitors. Antlers begin to sprout in spring and grow through the summer. Males use their antlers to fight other males for breeding rights during the fall rut. During the winter months, antlers are shed and the cycle begins anew. After the rut, winter can be hard on Zion's mule deer, and some individuals have an emaciated appearance by springtime. Low-nutritional quality winter vegetation contributes to their gaunt appearance. At the same time, they are also shedding their gray winter fur for their brown summer coat.

The old and sick mule deer are rarely preyed upon in Zion Canyon. Mountain lions, their main predator, usually avoid Zion Canyon because of the crowds. However, some deer or their fawns are eaten by coyotes and bobcat.

Fawns are born during late May or early June, usually as twins. The babies are often spotted alone in the grass or under a tree. Fawns should not be disturbed, as their mother is nearby, and they are simply waiting for her return.
