Chalcorana labialis
In 3 days ~30% in a week ~50%
Chalcorana labialis, also known as the white-lipped frog, is a species of "true frog" in the family Ranidae. As currently known, it is endemic to Peninsular Malaysia, although it might also occur in Singapore. Molecular data suggest presence of three distinct lineages in the same area, one of which is not closely related to Chalcorana labialis and which could represent an unnamed species.
Adult males measure 37–48 mm (1.5–1.9 in) and adult females 44–71 mm (1.7–2.8 in) in snout–vent length. The tympanum is distinct. The fingers have well-developed discs but no webbing. The toe discs are somewhat smaller; the toes have extensive webbing. The dorsum varies from dark green to pale yellow, with or without brown spots on the back. The upper lip is creamy yellow or white. The ventral surfaces are cream-coloured. The hind limbs may have dark cross-bars.
Chalcorana labialis occurs on vegetation by forest streams and swamps. It is common. As of April 2019, this species has not been assessed for the IUCN Red List of Threatened Species. Wikipedia →

With luck
About 10% of wildlife watchers report a White-lipped Frog sighting in Singapore on a given day, based on 156 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 20 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.
March to December
In those months about 10% of wildlife watchers report a White-lipped Frog in Singapore on a given day, against under 5% in January and February, the lowest months.
2nd of 2
Of the 2 cities where we can rate White-lipped Frog sightings, Singapore ranks 2nd at about 10%. The best odds are in Kuala Lumpur (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the White-lipped Frog is recorded against all the amphibians logged in Singapore (156 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.
