SAN DIEGO (Nov. 30, 2023) – Scientists at San Diego Zoo Wildlife Alliance have achieved a major milestone in saving wildlife species: With a blue-eyed black lemur’s cells recently added to its Wildlife Biodiversity Bank’s Frozen Zoo®, the nonprofit conservation organization’s unique collection of genetic material now contains 11,00o individual cell lines from more than 1,250 species and subspecies—some critically endangered. No other biobank in the world has a comparable number of living cell lines, with the potential to reverse losses of genetic diversity and contribute to population sustainability for  endangered and threatened wildlife species.

SAN DIEGO (Nov. 27, 2023) – For the third consecutive year, San Diego Zoo Wildlife Alliance will partner with the Tournament of Roses in Pasadena and participate in the 135th Rose Parade® presented by Honda on New Year’s Day. San Diego Zoo Wildlife Alliance’s parade float theme—“It Began with a Roar”—will feature a myriad of heartwarming stories from the San Diego Zoo that have inspired generations to care for and protect wildlife.

SAN DIEGO (Nov. 27, 2023) – When a mysterious illness called “sea star wasting syndrome” decimated 95% of the sunflower sea star population, and some 20 other sea star species along the Pacific Coast from Baja to Alaska in 2013, scientists rallied to understand the factors that caused such a massive wasting event. Now as part of the greater recovery initiative, in a scientific first, dozens of baby sunflower sea stars were hatched and are thriving thanks to a breakthrough in reproductive cell cryopreservation technology.

SAN DIEGO (Nov. 15, 2023) – There is a new, tiny face at the San Diego Zoo. A De Brazza’s monkey was born Oct. 28 to parents Lillie and Augustus, and it is the first De Brazza’s monkey born at the Zoo in 26 years. The little primate, whose gender has not yet been determined, can be seen holding tightly to its very attentive mother’s chest while they bond. In the next few weeks, the infant is expected to start walking and climbing. It will stay close to its mother until it is weaned, at around 1 year old.

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.

In the quest to save a true Southwest icon, we've teamed up with the California Mountain Lion Project.

SAN DIEGO (Nov. 9, 2023) – A binational team of scientists, using creativity and innovation, adorned dozens of endangered thick-billed parrots with tiny solar-powered satellite transmitters to track and reveal their winter migratory nesting sites in the remote treetops of the Sierra Madre Occidental ranges. Their research reveals new critical habitat, 80% of which has no formal protection.

Biodiversity banking is a critical component of conservation, and the need for it is more urgent than ever. 

LOS ANGELES, SAN DIEGO, and PORTLAND, Ore. (Oct. 16, 2023) – The U.S. Fish & Wildlife Service (Service) is sharing early results from the historic vaccine trial for highly pathogenic avian influenza (HPAI) in California condors (Gymnogyps californianus). As reported by the Service’s Incident Command leading the effort, results from the first test group showed that 60% of the condors produced measurable antibodies that are expected to provide partial protection against mortality from HPAI if the birds are exposed. 

SAN DIEGO (Oct. 12, 2023) – Two critically endangered Sumatran tiger cubs emerged from their den today at the San Diego Zoo Safari Park. The cubs, born July 12, stepped out to explore their outdoor habitat, much to the delight of wildlife care staff and volunteers.
