Diasporus diastema is a species of frog in the family Eleutherodactylidae. Common names include common tink frog or dink frog, supposedly because of the loud metallic "tink" sound that the male frog makes during the night. It is found in Central America, from Honduras through Nicaragua and Costa Rica to Panama. Its natural habitats are tropical humid lowland forests and montane forests, but it can use very disturbed habitats. It is found from sea level to 1,620 m (5,310 ft) elevation.
Its color during daylight hours, when it hides, is grayish brown with spots or bars; when it emerges at night and becomes active, the frog takes on a pale pink or tan color. The adult female reaches up to 1 inch (24 mm) long, and the male about 3/4 inch (21 mm). The tink frog has no free-swimming tadpole stage, and instead emerges as a miniature frog directly from the egg. Eggs are laid in bromeliads and tended by the male.
The diet of the tink frog consists mainly of ants and other arthropods. Kinsey, T. B. Dink Frogs. The Firefly Forest. Retrieved May 2013. Strieter, A. Common Tink Frog. Anywhere Costa Rica. Retrieved May 2013. Media related to Diasporus diastema... Wikipedia →

Possible
About 20% of wildlife watchers report a Tink Frog sighting in Piedras Blancas National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 33 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Tink Frog is recorded against all the amphibians logged in Piedras Blancas National Park (20 verified sightings from 2019 to 2026), 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.
