The Sonoran pronghorn, also known as the "desert ghost," is a rare animal native to the deserts of the southwestern United States and northern Mexico. Another subspecies, the Peninsular pronghorn, was once found in California. The Sonoran pronghorn earned its nickname due to its ability to blend into the desert landscape with its light tan color and remarkable speed.
This species can reach speeds of up to 60 miles per hour, a trait believed to have developed as a defense against cheetahs that once lived in North America. Despite their speed, Sonoran pronghorns are endangered, with fewer than 30 individuals left in the wild at one time. Conservation efforts have helped their numbers gradually recover, but ongoing protection is necessary for their survival. The Living Desert Zoo collaborates with governments and NGOs to potentially reintroduce them to California soon.
One notable adaptation of the Sonoran pronghorn is its ability to survive on minimal water intake—an essential trait for desert living. The animal derives most of its moisture from plants such as cacti and shrubs and has kidneys capable of concentrating urine to minimize water loss. Conservation initiatives include breeding programs and habitat restoration in both the U.S. and Mexico, which have contributed to population growth. Nonetheless, significant threats like climate change and drought persist.
"The Sonoran pronghorn is a symbol of desert resilience," states Dr. Luis Ramirez Yanez, Curator of Conservation at The Living Desert Zoo. Protecting this species is part of a broader effort to preserve fragile desert ecosystems.
