The Columbia spotted frog (Rana luteiventris) is a North American species of frog. It is green to brown in color with spots on the dorsal surface. The belly and upper lip are white in color. Individuals can be distinguished from other Rana species by their shorter back legs, narrow snout, and upturned eyes. Since they spend most of their time in the water, they also have more webbing in their hind feet than similar species. Although not threatened, this animal has been studied as a model species for the effects of habitat fragmentation.
The Columbia spotted frog is a medium-sized frog reaching lengths of up to 3.5 in (89 mm). Its color ranges from a dark, olive green to light brown with irregularly shaped black spots on its back and legs (rendering its name). Its skin texture, like the rest of the genus, varies from a rough to a smooth texture, with small folds of skin along the back. This frog exhibits a unique feature regarding its color. A light-colored strip runs along the upper lip, and the ventral sides of the frog are usually colored either pink or yellow, but only in the adult form.

With luck
About 10% of wildlife watchers report a Columbia Spotted Frog sighting in Jasper National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Columbia Spotted Frog in Jasper National Park on a given day, against under 5% in October to May, the lowest months. That is one of Jasper National Park's wettest months, with about 130 mm of rain against 55 mm in April.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Columbia Spotted Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Columbia Spotted Frog sightings, Jasper National Park ranks 4th at about 10%. The best odds are in Glacier National Park (United States, about 30%), Grand Teton National Park (United States, about 20%) and Yellowstone National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Columbia Spotted Frog is recorded against all the amphibians logged in Jasper National Park (10 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.
