Scientists in Southern California said that the red-legged frog is returning after many years of decline. On January 30, artificial intelligence found the frog’s breeding call in ponds near the U.S.-Mexico border. This frog was once common along the California coast but disappeared from most areas. The loss happened because of human development, drought, disease, and the introduction of bullfrogs. In 2006, researchers found a small group in Baja California, Mexico. Since 2018, egg masses have been moved with permission from Mexico to the United States. Today, more than 100 adult frogs live in Southern California ponds, showing signs of recovery.The project uses both science and teamwork between the two countries. Artificial intelligence helps by identifying frog sounds in noisy environments, which saves scientists many hours of listening. This technology also helps experts check breeding, watch for threats, and study the health of the ponds. Problems such as climate change, drought, and continued construction still create risks for frogs. However, scientists believe that the return of the red-legged frog shows that cooperation and technology can help protect endangered animals.
