Yosemite Series - Mule Deer In A Field Stock Image

Mule deer at Yosemite National Park in California. HTBphotos by John and Katharina Notarianni. In Yosemite Valley, mule deer are especially common, seen browsing on leaves and tender twigs from trees, grass, and herbs. Male mule deer grow antlers each year and are a factor in the dominance hierarchy among males, both visually, and in jousting among males for mating access to females.
