Polypedates maculatus, the Indian tree frog, or Chunam tree frog, is a common species of tree frog found in South Asia. It was described by John Edward Gray in 1830. Although now considered as a separate species again, for a time, the Himalayan tree frog was considered as a subspecies of the Indian tree frog (as P. m. himalayensis). Polypedates leucomystax, a very similar species, was formerly included in P. maculatus.
These frogs measure about 7–8 cm in body length. They are mostly brownish, yellowish, greyish, or whitish above, with darker spots or markings, rarely with an hourglass-shaped figure on the back of the head and the front of the back. The loreal and temporal regions are dark; there is a light line on the upper lip. The hind side of the thighs has round, yellow spots, which are usually separated by a dark-brown or purplish network. The skin is smooth above, and granulated on the belly and under the thighs; a fold extends from the eye to the shoulder. Males have internal vocal sacs.
The vomerine teeth are arranged in two more or less oblique series between the choanae or commencing close to the inner front edge of the latter. The skin of head is free;... Wikipedia →

Possible
About 30% of wildlife watchers report a Chunam Tree Frog sighting in Minneriya National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 10 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
May and June
In those months about 50% of wildlife watchers report a Chunam Tree Frog in Minneriya National Park on a given day, against under 5% in December and January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chunam Tree Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 4
Of the 4 parks where we can rate Chunam Tree Frog sightings, Minneriya National Park ranks 3rd at about 30%. The best odds are in Wilpattu National Park (Sri Lanka, about 50%) and Yala National Park (Sri Lanka, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Chunam Tree Frog is recorded against all the amphibians logged in Minneriya National Park (31 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.
