The Antilles coquí (Eleutherodactylus johnstonei), also known by the common names Johnstone's whistling frog, Montserrat whistling frog, Barbados whistling frog and Lesser Antillean whistling frog, is a species of frog in the family Eleutherodactylidae. It is native to the Lesser Antilles, but has spread across the world and is considered an invasive species.
Thomas Barbour first described the species in 1914, and gave it the specific name johnstonei after Robert S. Johnstone, Chief Justice of Grenada and the Grenadines, for his support of naturalists. The species similarity to Eleutherodactylus martinicensis, and the taxonomic history of Eleutherodactylus as a whole, has according to Hinrich Kaiser and Jerry D. Hardy Jr. been a source of confusion in determining which old publications are describing Eleutherodactylus johnstonei and which are describing a different species.
The snout-to-vent length of the species is around 35 mm (1.4 in) for females 25 mm (0.98 in) for males, but variation is high, especially so between different populations of the frog. Individuals have colourations ranging from brown to a greyish-tan, usually with colourful patterns... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Johnstone's Whistling Frog is recorded against all the amphibians logged in Medellín (14 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.
