Buergeria choui is a species of frog in the family Rhacophoridae. Prior to its description in 2020, it was confused with Buergeria japonica. It is found in northwestern Taiwan and in the southern part of the Ryukyu Archipelago, Japan, specifically on the Yaeyama Islands. Common name Yaeyama Kajika frog has been proposed for it. The specific name choui honors Wen-Hao Chou from the National Museum of Natural Science (Taiwan), the first person to pay attention to the variation within the former Buergeria japonica.
Buergeria choui is known from Iriomote and Ishigaki Islands in the Southern Ryukyus and from the northwestern parts of Taiwan. The true Buergeria japonica is now considered a Central and Northern Ryukyus endemic, while the former B. japonica elsewhere in Taiwan are now classified as Buergeria otai.
Adult males measure 25–29 mm (1.0–1.1 in) and adult females 30–36 mm (1.2–1.4 in) in snout–vent length. The snout is truncate. The tympanum is conspicuous; the supratympanic fold is evident. The forelimbs are moderate. The fingers have no webbing but have tips expanded into small discs. The hindlimbs are slender and very long. The toes have fleshy... Wikipedia →

With luck
About 10% of wildlife watchers report a Yaeyama Kajika Frog sighting in Taipei on a given day, based on 135 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June to August
In those months about 20% of wildlife watchers report a Yaeyama Kajika Frog in Taipei on a given day, against under 5% in February and November–December, the lowest months. Those are among Taipei's wettest months, with about 230 mm of rain a month against 90 mm in February.
Among the best
Of the 2 cities where we can rate Yaeyama Kajika Frog sightings, Taipei ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Taichung (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Yaeyama Kajika Frog is recorded against all the amphibians logged in Taipei (135 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.
