Quasipaa exilispinosa
In 3 days ~40% in a week ~70%
Quasipaa exilispinosa is a species of frog in the family Dicroglossidae. It is known under many common names, including Hong Kong spiny frog, common spiny frog, lesser spiny frog, little spiny frog, and Hong Kong paa frog. It has a patchy distribution in southern China including Hong Kong. Its natural habitats are subtropical hill streams in forests or shrublands, and sometimes also seepages, stream-fed marshes, and forests. It is threatened by over-collecting for human consumption and by habitat loss.
As hinted by common names "lesser" or "little" spiny frog, Quasipaa exilispinosa are relatively small among Quasipaa and the related frogs. Males grow to a snout–vent length of about 61 mm (2.4 in) and females to 57 mm (2.2 in). Tadpoles are up to about 39 mm (1.5 in) in length. Wikipedia →

Possible
About 20% of wildlife watchers report a Hong Kong Spiny Frog sighting in Hong Kong on a given day, based on 146 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 16 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August and September
In those months about 30% of wildlife watchers report a Hong Kong Spiny Frog in Hong Kong on a given day, against about 10% in February–May and November–December, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Hong Kong Spiny Frog sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Hong Kong Spiny Frog sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Dicroglossidae
The closest relatives of the Hong Kong Spiny Frog that you can see in Hong Kong (family Dicroglossidae, Fork-tongued Frogs) are Hong Kong Rice-paddy Frog (about 10%) and Asian Peters Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hong Kong Spiny Frog is recorded against all the amphibians logged in Hong Kong (146 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.
