Frogs getting jumpy over drought
An extended drought in California is taking its toll, not only on the local people but the local wildlife as well.
Mountain yellow-legged frogs are showing signs of stress related to the conditions.
Conservationists released 300 tadpoles into protected sites in the San Hacinto mountains 12 months ago and have been checking their progress.
The species has been brought back from the brink of extinction in recent years, despite the challenges imposed by wildfires, habitat destruction and disease.
And even though their stress levels are up, they seem to be in good shape.
Researchers believe a quarter of the tadpoles survived their first 12 months, boosting the local population, which they believe is around 200 frogs.
