Peron's tree frog (Pengilleyia peronii), also known as the emerald-spotted tree frog, emerald-speckled tree frog, laughing tree frog, and maniacal cackle frog, is species of tree frog in the family Pelodryadidae. It is a common frog found in Australia.
Peron's tree frog is one of the most variably coloured frogs in Australia, with the ability to change colour in less than one hour. They don't like to be handled for long periods of time. They also vary in shades of grey and brown, where their lightest is almost white. The frog has mottled yellow and black thighs, armpits, and groin. Occasionally, emerald spots are found on the back, which increase in number with age. A characteristic uncommon in the family Pelodryadidae is pupils which appear cross-shaped. This characteristic is only shared with Tyler's tree frog within the genus Pengilleyia. The male Peron's tree frog is about 44–53 mm, while females are 46–65 mm.
These frogs prefer living in places full of climbing material, (stones and sticks), and may remain in water for long periods of time. The call of Peron's tree frog is a high-pitched cackle, giving it the common names... Wikipedia →

Possible
About 30% of wildlife watchers report a Peron's Tree Frog sighting in Blue Mountains National Park on a given day, based on 112 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 12 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.
October to May
In those months about 30% of wildlife watchers report a Peron's Tree Frog in Blue Mountains National Park on a given day, against about 10% in June to September, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Peron's Tree Frog sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 7
Of the 7 parks where we can rate Peron's Tree Frog sightings, Blue Mountains National Park ranks 4th at about 30%. The best odds are in Booderee National Park (Australia, about 40%), Hattah-Kulkyne National Park (Australia, about 30%) and Royal National Park (Australia, about 30%).

GBIF citizen-science records
It is estimated from how often the Peron's Tree Frog is recorded against all the amphibians logged in Blue Mountains National Park (112 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.
