The Sonoran pronghorn is the fastest mammal in North America and can travel up to speeds of 60 miles per hour.
At least 21 types of snakes call the refuge home, including 6 rattlesnake species. They are an important part of the desert community.
Exciting Night Life
When the sun sets and the desert cools, a host of refuge animals stir, including ringtail cats, pocket mice and 11 species of bats.
Light-colored fur helps mammals reflect heat rather than soak it in. The scales of lizards serve the same purpose.
Many desert animals burrow, including tortoise. They burrow down (sometimes up to many feet) to avoid the summer heat and winter cold.
Due to the success of recovery efforts, pronghorn numbers have recently increased to historic average numbers. To protect the young Sonoran pronghorn, much of the refuge has been closed since 2003 during fawning season -- from mid-March to mid-July -- but the closure may be suspended beginning in 2014. The purpose of the temporary closure has been to minimize disturbance to herds containing fawns. If spooked, the adults will often run several miles and use up valuable energy they need to maintain themselves and their fawns. If their nutritional requirements are not met, this can result in the loss of fawns. During Fawning Season
Draft Compatibility Report
U.S. Customs and Border Protection (CBP) proposes to replace an existing radio repeater co-located with Fish and Wildlife Service communications equipment on Buck Peak with updated land mobile radio (LMR) tactical communications (TacCom) equipment and to install up to two new repeaters at Granite Mountain and Christmas Pass. All three sites are located in designated wilderness within the Cabeza Prieta National Wildlife Refuge (CPNWR). The CBP, at CPNWR’s request, has designed sufficient capacity in their systems proposed at Buck Peak and Christmas Pass to allow for the installation and operation of CPNWR equipment.

Close to being lost forever, Sonoran pronghorn are making a comeback thanks to an active management program and captive-breeding program. Learn how the U.S. Fish and Wildlife Service and its partners are applying the best available science to ensure North America’s fastest land animal remains forever at home on the range.Sonoran Pronghorn Recovery Brochure

Feeding on the saguaro’s nectar and fruit, the endangered lesser long-nosed bat helps pollinate and spread the saguaro seed. The bats are able to reach deep into the cactus’ blossoms using their elongated, narrow snouts. Their hairy heads get covered with the pollen and as the bats fly from cactus to cactus, they transfer pollen to other saguaro blossoms – pollination occurs! For this and other reasons, lesser long-nosed bats play an extremely important role in maintaining healthy deserts.
