The banded stream frog (Strongylopus bonaespei), also known as the banded sand frog, Cape grass frog, Cape stream frog, long-toed frog, mountain frog or Jonkersberg frog, is a species of frogs in the family Pyxicephalidae. It is endemic to South Africa.
The banded stream frog is a slender streamlined frog with a long pointed snout and long hind legs where the distance from the ankle to the knee is greater than half the length of the body. When the frog is sitting the fourth toe on the hind foot extends past the front foot. The dorsal skinis pale but is marked with brown, gold, grey, and sometimes red to orange stripes running along the body while the legs have bands which run across them. The anterior skin is smooth and white.
The banded stream frog is endemic to South Africa, and is almost endemic to the Western Cape but its distribution just extends into the western Eastern Cape. It range extends from extending the Cape Peninsula north into the Cederberg Mountains, and east as far as Witelsbos Forest Reserve in the Tsitsikamma Mountains.
The banded stream frog typically inhabits montane fynbos but it occasionally occurs on the margins... Wikipedia →

With luck
About 10% of wildlife watchers report a Banded Stream Frog sighting in Table Mountain National Park on a given day, based on 73 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February, April–September and November–December
In those months about 10% of wildlife watchers report a Banded Stream Frog in Table Mountain National Park on a given day, against under 5% in January, March and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Banded Stream 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.
Only Table Mountain National Park, in our data
Table Mountain National Park is the only park on Wallace's Line with enough records to rate Banded Stream 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 Banded Stream Frog is recorded against all the amphibians logged in Table Mountain National Park (73 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.
