Lithobates clamitans or Rana clamitans, commonly known as the green frog, is a species of frog native to eastern North America. The two subspecies are the bronze frog and the northern green frog. These frogs, as described by their name, typically have varying degrees of green heads. These frogs display significant acts of territoriality, with males being the primary actors. Male green frogs use this technique against other male frogs in addition to other intruders that might have interest in nearing their territory. Territoriality also plays a role in mating, as females favor males who are strong in this field and exhibit strong mating calls. Male green frogs use four different types of breeding calls to attract potential female mates. Predators of the eggs of green frogs include beetles, water bugs, and water scorpions. Adult frogs are typically threatened by several types of birds.
Lithobates clamitans is a member of the true frog family Ranidae and genus Lithobates. Litho- meaning stone, a rock climber. Originally classified in the genus Rana until systematic revision, features of the genus are true frogs with slim waist and wrinkled skin, found across much of Eurasia... Wikipedia →

It is the 2nd most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Green Frog is recorded against all the amphibians logged in Voyageurs National Park (20 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.
