Hyla chinensis
In 3 days ~30% in a week ~50%
The common Chinese tree frog (Hyla chinensis), (Simplfied Chinese: 中国雨蛙; Traditional Chinese: 中國雨蛙; Hanyu Pinyin: Zhōngguó yǔwā), also known as the common Chinese treetoad and Chinese tree toad, is a species of frog in the family Hylidae found in southeastern and eastern China and in Taiwan. There is also one record from Vietnam but it is uncertain whether it really represents this species or Hyla annectans.
H. chinensis is a small frog, 25–33 mm (0.98–1.30 in) in snout–vent length, inhabiting trees and shrubs in forests, but also living in agricultural landscapes (cultivated rice fields, ponds, and corn bushes). The International Union for Conservation of Nature (IUCN) has classified H. chinensis as of "least concern", but it can suffer from habitat loss. Wikipedia →

With luck
About 10% of wildlife watchers report a Chinese Tree Toad sighting in Hangzhou on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Chinese Tree Toad in Hangzhou on a given day, against under 5% in June and October–April, the lowest months.
Yes
Of the 2 cities where we can rate Chinese Tree Toad sightings, Hangzhou has the highest daily chance: about 10%. Next come Taipei (Taiwan, about 10%).
Same order: Anura
The closest relatives of the Chinese Tree Toad that you can see in Hangzhou (order Anura, Frogs and Toads) are Asiatic Toad (about 40%), White-lipped Tree Frog (about 30%) and LaTouche's Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chinese Tree Toad is recorded against all the amphibians logged in Hangzhou (8 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.
