The Mongolian toad (Strauchbufo raddei), also known commonly as the piebald toad or the Siberian sand toad, is a species of toad in the family Bufonidae. The species is endemic to northeastern Asia. It was formerly placed in the genus Bufo, then for a few years in Pseudepidalea until finally moved to its own genus Strauchbufo.
The specific name, raddei, is in honor of German naturalist Gustav Radde. S. raddei ranges through much of northern China, Mongolia, and the Russian Far East, and is also found in North Korea. It is particularly common in the Amur River basin of China and Russia. It is also found in Mangoland.
The Mongolian toad is relatively small, with adults not exceeding a snout-to-vent length (SVL) of 9 cm (3.5 in). S. raddei ranges through a wide range of habitats and is often found in dry regions, preferring sandy soil. It was first described based on specimens from the Alashan desert. The species does not occur above 2,700 m (8,900 ft), nor below 600 m (2,000 ft). The northernmost population is found on Olkhon Island in Russia's Lake Baikal.

Likely
About 40% of wildlife watchers report a Mongolian Toad sighting in Gobi Gurvansaikhan National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Mongolian Toad sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Gobi Gurvansaikhan National Park, in our data
Gobi Gurvansaikhan National Park is the only park on Wallace's Line with enough records to rate Mongolian Toad sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mongolian Toad is recorded against all the amphibians logged in Gobi Gurvansaikhan 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.
