Gray's stream frog (Strongylopus grayii) is a fairly small species of frog in the family Pyxicephalidae. It is a ground dweller, living mainly in vegetation such as sedges, generally brown, slenderly built and agile, with long, practically unwebbed toes.
Strongylopus grayii is a fairly small species (snout-to-vent length of breeding specimens about 25 to 50 mm). The snout is not as pointed as most of the genus, the snout profile being rather reminiscent of the Cape river frog. The ventral skin is smooth, pale to white, the dorsal skin colour is variable, generally shades of brown with darker blotches. Similar blotches form bars across the upper surfaces of the thighs. Often it has a vertebral line in a lightly contrasting colour, pale to reddish. Some colour variants have a broad russet band down the back. The dorsal skin is textured with scattered small, raised ridges, largely longitudinal. The tympanum is smaller in diameter than the eye, but more than half the diameter. Though clearly visible, it is inconspicuous, being situated in a dark facial band of pigment behind the eye. The facial band extends more or less from the nostril, across the lower part of the eye...

Likely
About 40% of wildlife watchers report a Clicking Stream Frog sighting in De Hoop Nature Reserve on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
June
In that month about 80% of wildlife watchers report a Clicking Stream Frog in De Hoop Nature Reserve on a given day, against under 5% in January and September, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Clicking Stream Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate Clicking Stream Frog sightings, De Hoop Nature Reserve has the highest daily chance: about 40%. Next come Table Mountain National Park (South Africa, about 30%) and Garden Route National Park (South Africa, about 20%).
Same family: Pyxicephalidae

GBIF citizen-science records
It is estimated from how often the Clicking Stream Frog is recorded against all the amphibians logged in De Hoop Nature Reserve (21 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.
