SAN DIEGO, PALM DESERT, Calif. (April 15, 2024) – Seventy critically endangered Mojave desert tortoises have successfully emerged from their winter burrows after being reintroduced into their native habitat on Edwards Air Force Base in Southern California. San Diego Zoo Wildlife Alliance and The Living Desert Zoo and Gardens, the global authority on desert plant and wildlife conservation, are working in partnership with Edwards Air Force Base, the U.S. Fish and Wildlife Service and the U.S. Geological Survey, using headstarting techniques designed to increase the survival rate for young tortoises. The cohort of young tortoises was the first in the program to be reintroduced into the wild after receiving a combination of an indoor- and outdoor-rearing. Within 24 hours of reentering their native habitat, the tortoises were exhibiting positive natural behaviors by constructing new burrows or modifying existing burrows for shelter. Now, six months later, they have emerged after winter brumation—a state of deep sleep specific to reptiles—and are spending more time basking at burrow entrances. Scientists are currently conducting health assessments and replacing radio transmitters on the tortoises to continue monitoring their success and better understand the juvenile age class.

SAN DIEGO (Jan. 30, 2024) – San Diego Zoo Wildlife Alliance and San Diego State University (SDSU) are joining forces to usher in a new way of studying snakes. In a collaboration between San Diego Zoo Wildlife Alliance and Rulon Clark, Ph.D., professor of biology at SDSU, biologists are tagging wild rattlesnakes with external transmitters and accelerometers. Previously, telemetry devices on snakes had to be surgically implanted—severely limiting this area of study. San Diego Zoo Wildlife Alliance and SDSU are among the first to use acceleration technology to study snakes.

African penguins and California least terns share marine habitat challenges.

SAN DIEGO (Dec. 19, 2023) – For more than a decade, the San Diego Zoo Wildlife Alliance’s entomology team has collaborated with Australia’s Melbourne Zoo to maintain populations of the critically endangered Lord Howe Island stick insect. For the first time in North America, visitors to the San Diego Zoo will have the opportunity to see these rare, nocturnal insects in a specialized habitat at the Zoo’s Wildlife Explorers Basecamp.

It takes a team and some careful observation to keep the San Diego Zoo's colony of 25 black-and-white African penguins in the pink.
