Possible
About 20% of wildlife watchers report a Guenther's Frog sighting in Hong Kong on a given day, based on 178 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 16 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and June–August
In those months about 30% of wildlife watchers report a Guenther's Frog in Hong Kong on a given day, against under 5% in January, the lowest month. Those are among Hong Kong's wettest months, with about 200 mm of rain a month against 25 mm in December.
4th of 12
Of the 12 cities where we can rate Guenther's Frog sightings, Hong Kong ranks 4th at about 20%. The best odds are in Taichung (Taiwan, about 30%), Taipei (Taiwan, about 20%) and Guangzhou (China, about 20%).
Same family: Ranidae
The closest relatives of the Guenther's Frog that you can see in Hong Kong (family Ranidae, Typical Frogs) are Longtoushan Large Odorous Frog (about 10%), Large Odorous Frog (about 10%) and Hong Kong Cascade Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guenther's Frog is recorded against all the amphibians logged in Hong Kong (178 verified sightings), 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.
