California Mule Deer

Odocoileus hemionus californicus

There are two main groups of mule deer, mule deer and black-tailed deer, they are classified as different species but they do hybridize often. According to genetic analysis the mule deer evolved from the black-tailed deer and the mitochondrial DNA between the mule deer and the white-tailed deer are very similar.

During most of the year there is usually one female and one fawn, lately there hasn’t been any sign of the fawn so it might have separated from the mother already. During the fall and early winter there are a few males that walk by the camera, but they become rare as hunting season continues.

  • Number of confirmed specimens : 3
