The Cuban tree frog (Osteopilus septentrionalis) is a large species of tree frog that is native to Cuba, the Bahamas, and the Cayman Islands; but has become invasive in several other places around the Americas. Its wide diet and ability to thrive in urban areas has made it a highly invasive species with established colonies in places such as Florida, the Hawaiian island of Oahu, and the Caribbean Islands. These tree frogs can vary in size from 2 to 5.5 inches (5 to 12.7 cm) in length. Due to their large size, Cuban tree frogs can eat a wide variety of things, particularly native tree frogs, and their removal has shown to result in an increase in the amount of native tree frogs in an area. The tadpoles of Cuban tree frogs also heavily compete with native frog tadpoles, which can cause negative effects in body mass, size at metamorphosis, and growth rates for the native tadpoles.
Cuban tree frogs are the largest tree frogs in North America, ranging from 2 to 5.5 inches or (5 to 12.7 cm) in length. Cuban tree frogs are mostly gray, brown, or green, with young frogs having more green coloration than adults. These frogs have rough, warty skin with blotchy or mottled patterning... Wikipedia →

Possible
About 30% of wildlife watchers report a Cuban Treefrog sighting in Miami on a given day, based on 1,632 verified sightings from GBIF citizen-science data. It is the most-seen of the 12 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–August and October
In those months about 40% of wildlife watchers report a Cuban Treefrog in Miami on a given day, against about 20% in January and February, the lowest months. Those are among Miami's wettest months, with about 160 mm of rain a month against 45 mm in January.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Cuban Treefrog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 5 cities where we can rate Cuban Treefrog sightings, Miami ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Orlando (United States, about 30%).
GBIF citizen-science records
It is estimated from how often the Cuban Treefrog is recorded against all the amphibians logged in Miami (1,632 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.
