The California red-legged frog (Rana draytonii) is a species of frog in the family Ranidae. The species is native to California (USA) and northern Baja California (Mexico). It was formerly considered a subspecies of the northern red-legged frog (Rana aurora). R. draytonii has an IUCN "Near Threatened" conservation status as of 2021, has a NatureServe conservation status of "Imperiled" as of 2015, and is a federally listed threatened species of the United States that is protected by law.
The California red-legged frog is found in California and extreme northern Baja California, northwestern Mexico. This species now occurs most commonly along the northern and southern Coast Ranges, and in isolated areas in the foothills of the Sierra Nevada mountains. The current southernmost California populations are on the Santa Rosa Plateau in Riverside County, and within the Upper Las Virgenes Canyon Open Space Preserve in the Simi Hills in eastern Ventura County, near the community of West Hills. In 2015, egg masses from the nearby Simi Hills were introduced to two streams in the Santa Monica Mountains. Juvenile frogs were found living at the locations a year later. Wikipedia →

With luck
About 10% of wildlife watchers report a California Red-legged Frog sighting in Yosemite National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a California Red-legged Frog in Yosemite National Park on a given day, against under 5% in May, July, September–October and December–March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most California Red-legged Frog sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Yosemite National Park, in our data
Yosemite National Park is the only park on Wallace's Line with enough records to rate California Red-legged Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the California Red-legged Frog is recorded against all the amphibians logged in Yosemite National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
