Liolaemus darwinii, commonly known as Darwin's tree iguana, is a species of lizard in the family Liolaemidae. It is endemic to Argentina. The specific name, darwinii, is in honor of English naturalist Charles Darwin, the author of On the Origin of Species.
The preferred natural habitat of L. darwinii is shrubland, at altitudes from sea level to 3,000 m (9,800 ft). The males of L. darwinii are brown with two yellow dorsal stripes that run along the spine, one on each side of the back. The females are solely brown.
L. darwinii eats various insects 5 cm (2.0 in) or less in length, including beetles and locusts. L. darwinii is diurnal. During nights and cold days, it burrows underground. It is a solitary and territorial. Males and females compete for territory.
L. darwinii is oviparous. The mating season is in mid-February, and the nesting time is eight months later. The hatchlings are 5 cm (2.0 in) long, and clutch size is typically between 10 and 12.

Likely
About 40% of wildlife watchers report a Bahia Blanca Smooth-throated Lizard sighting in Península Valdés on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 6 reptiles 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.
October and December–January
In those months about 50% of wildlife watchers report a Bahia Blanca Smooth-throated Lizard in Península Valdés on a given day, against under 5% in February and August–September, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Bahia Blanca Smooth-throated Lizard sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Península Valdés, in our data
Península Valdés is the only park on Wallace's Line with enough records to rate Bahia Blanca Smooth-throated Lizard sightings: about 40% of wildlife watchers there report one on a given day.
Same genus: Liolaemus
The closest relatives of the Bahia Blanca Smooth-throated Lizard that you can see in Península Valdés (genus Liolaemus, Smooth-throated Swifts) are Black-faced Smooth-throated Lizard (about 70%) and Graceful Tree Iguana (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bahia Blanca Smooth-throated Lizard is recorded against all the reptiles logged in Península Valdés (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.
