Pleurodema cinereum is a species of frog in the family Leptodactylidae. It is found in the Andes in northwestern Argentina, Bolivia, and southeastern Peru. Its common name is Juliaca four-eyed frog, after its type locality, Juliaca. Pleurodema borellii is possibly a junior synonym of this species.
Its natural habitats are open montane puna grasslands and semi-deciduous forests. Scientists have observed the frog between 600 and 4,200 m (2,000 and 13,800 ft) above sea level. Scientists have reported the frog in protected parks, many in Bolivia and two in Argentina: Los Andes Provincial Reserve and Laguna Pozuelos National Park.
Reproduction takes place in small permanent and temporary pools where pairs build floating foam nests. It is a common species facing no major threats. Wikipedia →

Likely
About 50% of wildlife watchers report a Juliaca four-eyed frog sighting in La Paz on a given day, based on 164 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 90% of wildlife watchers report a Juliaca four-eyed frog in La Paz on a given day, against under 5% in June, the lowest month. That is one of La Paz's wettest months, with about 140 mm of rain against 10 mm in June.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Juliaca four-eyed frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

GBIF citizen-science records
It is estimated from how often the Juliaca four-eyed frog is recorded against all the amphibians logged in La Paz (164 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.
