Mammals are a diverse group of animals, ranging from the delicate white-footed mouse to the elegant mule deer. Mammals have fur or hair, produce milk for their offspring, and are warm-blooded.

In the often extreme climate of the plateau country, animals use such survival strategies as hiding in their burrows or migration as well as physiological adaptations like hollow hairs for insulation or radiation of heat from body parts. Many animals in arid regions are nocturnal or crepuscular, using the cooler night to survive the heat of summer or the darkness of the late hours to escape notice of predators.
