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.

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. 11, 2023) – San Diego Zoo Wildlife Alliance has been recognized for its expertise in wildlife biobanking, and has partnered with the Species Survival Commission (SSC) of the world’s largest conservation organization—the International Union for Conservation of Nature (IUCN)—to form the new Center for Species Survival: Biodiversity Banking. The new center is the first ever to have a strategy focus rather than a taxonomic one.

Challenges are lurking in the watery world of black caimans—and their reptilian relatives.

Technology takes wing, and is playing a key role in Hawaiian hawk conservation.

SAN DIEGO (July 13, 2023) – After more than two years of dedicated work, San Diego Zoo Wildlife Alliance conservationists are achieving success breeding a critically endangered coastal bird: the milky stork. This breeding program is part of an 11th-hour effort with the Association of Zoos and Aquariums Taxon Advisory Group (AZA TAG) to assist the last remaining individuals of the species living in North America—helping them successfully reproduce, and bolster the world’s population of milky storks. 

For the people and jaguars who share space in the Peruvian Amazon, finding ways to coexist is key.

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.

For Andean bear conservation efforts to work, scientists must study the varying landscapes as well.

If you’re on the African savanna and near a particular type of tree, you’re listening to the duet of two species—one botanical and one arthropodan—working together in perfect harmony to survive.
