Ptenopus garrulus, also known commonly as the common barking gecko and the whistling gecko, is a species of lizard in the family Gekkonidae. The species is native to southern Africa. There are two recognized subspecies. The dorsal coloration of P. garrulus varies from reddish brown to grayish yellow to match the local substrate. Ventrally, it is white. The toes are strongly fringed. It has 110–190 rows of scales around the body at midbody. The subspecies P.g. garrulus has more than 160 rows, but the subspecies P. g. maculatus has fewer than 160 rows. Adults usually have a snout-to-vent length (SVL) of 4.5–6 cm (1.8–2.4 in), which is relatively small for the genus.
P. garrulus is found in Botswana, Namibia, South Africa, and Zimbabwe. The preferred natural habitats of P. garrulus are desert, shrubland, and savanna, at altitudes from sea level to 1,500 m (4,900 ft). P. garrulus is terrestrial and fossorial. Males vocalize from the entrances of their burrows at dusk and on moonlit nights.
P. garrulus preys upon ants, beetles, and termites. P. garrulus is oviparous. Two subspecies... Wikipedia →

Possible
About 20% of wildlife watchers report a Common Barking Gecko sighting in Kgalagadi Transfrontier Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 14 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Common Barking Gecko in Kgalagadi Transfrontier Park on a given day, against under 5% in May to August, the lowest months. That is one of Kgalagadi Transfrontier Park's wettest months, with about 40 mm of rain against almost none in July.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Common Barking Gecko sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 2 parks where we can rate Common Barking Gecko sightings, Kgalagadi Transfrontier Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Namib-Naukluft National Park (Namibia, about 20%).
Same family: Gekkonidae
The closest relatives of the Common Barking Gecko that you can see in Kgalagadi Transfrontier Park (family Gekkonidae, Typical Geckos) are Bibron's Thick-toed Gecko (about 30%) and Cape Thick-toed Gecko (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Barking Gecko is recorded against all the reptiles logged in Kgalagadi Transfrontier Park (15 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.
