SAN DIEGO (May 25, 2022) – A new study from scientists at San Diego Zoo Wildlife Alliance (SDZWA), published today in the Journal of Applied Ecology, found endangered mountain yellow-legged frogs being reared for release into the wild have a greater chance of survival if introduced to artificial currents at early stages of their development. While the findings support a growing body of evidence that suggests raising bred animals in an environment similar to where they will be released can boost survival rates, the study goes even further, showing the timing of experiential exposure may be critical to successful species recovery translocations.
SAN DIEGO (May 18, 2022) – A new study has found contaminants that were banned decades ago are still imperiling critically endangered California condors. The condors may be at increased risk for reproductive impairment because they consume dead marine mammals along the California coast.
SAN DIEGO (January 27, 2022) – Western burrowing owls, a declining species in Southern California, are increasingly being forced from their homes by development. A research team led by San Diego Zoo Wildlife Alliance, in collaboration with the U.S. Fish and Wildlife Service Palm Springs office, developed novel techniques using a bit of creative advertising to protect the displaced owls, including painting rocks to look like stains from bird droppings and playing recorded vocalizations.
(KAHULUI, MAUI) – An ambitious effort to rescue four tiny birds deep in a thick Hawaiian rainforest saw its first taste of success last Sunday (Dec. 5, 2021), giving hope to a critically endangered species driven to the brink of extinction by malaria—an unfortunate consequence of climate change.
Condor parthenogenesis—or reproduction without genetic contributions from a male—takes us by surprise.
