San Diego Zoo Global has achieved a major conservation milestone this month, releasing more than 260 endangered mountain yellow-legged frog adults and froglets and more than 680 tadpoles into the San Bernardino and San Jacinto Mountains. Working with U.S. Geological Survey (USGS) and other partners, the research team implanted radio-telemetry transmitters into a group of the adult frogs, which are expected to enter hibernation in the fall. This will be the first time transmitters have ever been used to track these frog populations during their annual hibernation cycle.

San Diego Zoo Global is excited to announce a historic, successful birth of a southern white rhino calf at the San Diego Zoo Safari Park—the conservation organization’s first rhino born following hormone-induced ovulation and artificial insemination. The mother, Victoria, gave birth to a healthy male calf Sunday, July 28, 2019, in the barn at the Nikita Kahn Rhino Rescue Center. Animal care staff on hand to witness the birth reported Victoria did extremely well and remained calm during the 30-minute labor.
