SAN DIEGO (April 19, 2023) – Scientists are elated with the recent birth of the world’s second successfully cloned Przewalski’s horse, supporting the concept that cloning can be used as a viable tool for genetic rescue and contribute to new options for fostering resilience and genetic sustainability of endangered species.

However, when those twins are Amur leopards—and fewer than 300 of those big cats are estimated to exist on Earth—the births are especially significant.

SAN DIEGO (March 14, 2023) – The San Diego Zoo continues to celebrate the arrival of twin Andean bear cubs—now 3 months old and venturing out of their private den into the guest-facing habitat. The cubs were born in December 2022 to second-time mother Alba, and sire Turbo. Since the twins’ birth, wildlife care specialists have been closely observing the bears via a closed-circuit video camera and an audio “baby monitor,” allowing Alba to care for her youngsters without interruption until they were ready to leave the den.

Frozen conservation is helping to secure the future for endangered species.

SAN DIEGO (March 3, 2023) – San Diego Zoo Wildlife Alliance hosted a “Toss the Tusk” event at the San Diego Zoo Safari Park earlier today, to help raise awareness about the devastating effects of elephant poaching. The event, organized by the Association of Zoos and Aquariums’ Wildlife Trafficking Alliance (AZA WTA) and the U.S. Fish and Wildlife Service (USFWS), encouraged the public to surrender unwanted ivory products to help ensure that their availability will not drive demand for the product
