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.

Black-tailed Jackrabbit(Lepus californicus)
Family: Leporidae (Hares and Rabbits)
Size: 18.3 - 25 in (46 - 64 cm)
Status: native; rare
Habitat: barren lands and prairies, meadows, fields
Black-tailed Jackrabbits with their long ears and powerful back legs are considered hares rather than rabbits. In addition, as opposed to rabbits, their young are born fully furred with open eyes and an ability to jump almost immediately. Adults can hop at very fast speeds. They can also leap long distances horizontally. Blood flowing close to the surface of their ears acts as a cooling mechanism during the day. They are mostly active at night, resting in the shade during the heat of the day. Black-tailed Jackrabbits survive on poor quality food eating vegetation from shrubs, small trees and grasses. They get all of their water from their food. They do not hibernate and serve as an important prey for raptors and carnivorous mammals.
