This guide initially displays all common mammals. Use the selectors below to view mammals of a particular shape, include rare mammals, or search for them by name.
Mammals are defined as warm-blooded vertebrates with hair or fur and sweat glands — in the females mammary glands, modified sweat glands, produce milk to nourish the young. Most mammals develop a placenta which enables the feeding of the fetus during gestation and give birth to live young. In addition, although most mammals walk on land, many have specific adaptations that allow them to swim, fly, leap between tree branches or even dig extensive tunnels. Many wild mammals are used for both food and fur. while other have been domesticated for their agricultural and scientific importance.
New Mexico ranks high for mammalian diversity in the states in the US and the Pajarito Plateau is home to many of these species. This guide describes all of the larger wildlife found in the area as well as the more common smaller animals with the most abundant being rodents. Local species range from carnivores like the mountain lion and bobcat to ruminants like elk and deer to to several varieties of bats.

The Gunnison's Prairie Dog is one of five prairie dog species in the US and the one that is found locally. They live in colonies of up to several hundred individuals made up of numerous smaller family groups. Each family group has its own set of burrows with separate areas for a nursery and sleeping quarters. They hibernate in their burrows during winter. During the warmer months they are most active in the early morning and late afternoon where their main activity involves finding food. They feed on grasses, herbs, and leaves, seeds, stems, roots and even insects depending on the season. Prairie Dogs have a very complex system of communication consisting of forms of physical contact and vocalization such as warning barks. The Gunnison’s Prairie Dog was considered for listing as a threatened species but the proposal was rejected in 2013.
