General Description


Mule deer, with lengths ranging from 1.2 to 2.1 meters, are easily recognized by their large ears, which measure approximately 75% of their head length. They have a black forehead, a white patch on their lower back, and a small black tail. Males can weigh up to 136 kg and engage in antler-based competitions during the mating season, while females, lacking antlers, have an average weight of about 45 kg.

Diet and Habitat


The mule deer are selective eaters that depend on herbaceous plants for nutrition and sustenance. Due to their small stomachs, they regurgitate and re-chew their food to aid digestion and support good stomach bacteria.

Life Expectancy


In the wild, mule deer typically inhabit rugged landscapes and live for 9 to 11 years. However, in captivity, they often exceed this lifespan, with an average lifespan of 20 years or more.
