The upland chorus frog (Pseudacris feriarum) is a species of chorus frog found in the United States. It was recently separated from the Western chorus frog (Pseudacris triseriata), being identified as an individual species rather than a subspecies. They are a rarely seen species, but their calls are frequently heard soon after rains in the spring time.
Within their range, this species is found in a variety of habitats that include: swampy areas of broad valleys, grassy swales, moist areas of woodlands and borders of heavily vegetated ponds. Upland chorus frogs are usually brown, grey-brown, or reddish-brown in color, with darker blotching. They grow from 0.75–1.5 inches (1.9–3.8 cm) in size. A white line is present on the head, above the upper lip. Dorsally, there are 3 longitudinal lines which may be complete or broken into spots and a triangular spot on the head usually connects with the middle stripe. Tend to be smaller with a slender waist and long limbs. Males possess a single, round vocal patch, which is yellow, grey or brown over a lighter background colour.

With luck
About 10% of wildlife watchers report an Upland Chorus Frog sighting in Great Smoky Mountains National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 36 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
February and March
In those months about 30% of wildlife watchers report an Upland Chorus Frog in Great Smoky Mountains National Park on a given day, against under 5% in April–August and November–January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Upland Chorus Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Great Smoky Mountains National Park, in our data
Great Smoky Mountains National Park is the only park on Wallace's Line with enough records to rate Upland Chorus Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Upland Chorus Frog is recorded against all the amphibians logged in Great Smoky Mountains National Park (17 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.
