SAN DIEGO (Nov. 14, 2023) – San Diego Zoo Wildlife Alliance, in collaboration with Omaha’s Henry Doorly Zoo and Aquarium, reintroduced more than 70 endangered mountain yellow-legged frogs into a lake located in the San Bernardino Mountains. This release marks the first time the Southern California distinct population segment of the mountain yellow-legged frog has been reintroduced into a lake instead of a mountain stream. The frogs were bred at San Diego Zoo Wildlife Alliance’s Beckman Center for Conservation Research between 2020 and 2022, and then reared at Omaha’s Henry Doorly Zoo and Aquarium. The cross-country effort to save this California frog is part of a robust conservation breeding and reintroduction research program aimed at restoring populations of this declining species throughout its historic range.
SAN DIEGO (Sept. 7, 2023) – The world’s second successfully cloned Przewalski’s horse is thriving at his home at the San Diego Zoo Safari Park. The foal, born Feb. 17, 2023, and his surrogate mother, a domestic quarter horse, were recently moved from his birthplace at ViaGen Pets & Equine cloning facility in Texas so he can learn the language of being a wild horse from his own species.
SAN DIEGO (June 6, 2023) – Researchers are currently tracking over 40 wild ‘io, also known as Hawaiian hawks, on Hawai‘i Island with lightweight, solar-powered GPS transmitters. This work is part of a collaborative effort to conserve this beloved species and one of its natural prey—the ‘alalā. Researchers with San Diego Zoo Wildlife Alliance and the State of Hawai‘i Department of Land and Natural Resources – Division of Forestry and Wildlife are collaborating on this effort as part of a large-scale GPS tracking program to better understand the extent to which ‘io move across the island and how they utilize different habitats. With the new insights that are gathered, scientists will be better equipped to conserve this iconic raptor, and simultaneously glean critical insights to aid in the future reintroduction of the ‘alalā, also called the Hawaiian crow, to their native habitats. The aim is to ensure that both ‘alalā and ‘io can coexist in their native habitats, as they previously did for many years.

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.
