Atelopus glyphus, the Pirri harlequin frog or Pirri Range stubfoot toad, is a species of toad in the family Bufonidae found in Colombia and Panama within the Northwestern Andean montane forests. Its natural habitats are subtropical or tropical moist montane forests and rivers.
This species is terrestrial, and breeds in forest streams. The reproductive biology is not well-known, but other Atelopus species are known to attach their eggs to the undersides of rocks in swift-moving streams during dry seasons when the water level is low. The eggs are laid in strings, and the larvae develop as the wet season begins. All Atelopus tadpoles have large ventral suckers, allowing them to hang on to rocks even in torrents.
The biggest threat to this and other, similar species is chytridiomycosis. The disease has affected many other species of Atelopus, particularly those associated with montane streams. This toad lives in two protected areas in Panama and Colombia. This guarantees some suitable habitat, but does not protect it from the chytrid fungus.
It is also threatened by habitat loss, urbanization, climate change, pesticides, and intensified... Wikipedia →

With luck
About 10% of wildlife watchers report a Pirri Harlequin Frog sighting in Darién National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March and April
In those months about 20% of wildlife watchers report a Pirri Harlequin Frog in Darién National Park on a given day, against under 5% in May to February, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Pirri Harlequin Frog sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Darién National Park, in our data
Darién National Park is the only park on Wallace's Line with enough records to rate Pirri Harlequin Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Bufonidae
The closest relatives of the Pirri Harlequin Frog that you can see in Darién National Park (family Bufonidae, True Toads) are Forest Toad (about 30%), Giant Marine Toad (about 30%) and Leaf Litter Toad (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pirri Harlequin Frog is recorded against all the amphibians logged in Darién National Park (5 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.
