The smooth snake (Coronella austriaca) is a species of small dimensions in the family Colubridae. The species is found in northern and central Europe, but also as far east as northern Iran. The Reptile Database recognizes two subspecies as being valid, including the nominotypical subspecies described here.
There are two subspecies: Coronella austriaca is found from the south of England through France and the Low Countries to northern Spain and Portugal, Germany, Norway and Sweden (as far north as latitude 63°), Latvia, Lithuania, Estonia, Switzerland, Austria, Italy and Sicily (but not in Corsica or Sardinia), the western Balkans and Greece, and European Russia as far north as latitude 57°.

With luck
About 10% of wildlife watchers report a Smooth Snake sighting in Vienna on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 12 reptiles 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.
April–May, July–August, October and December
In those months about 10% of wildlife watchers report a Smooth Snake in Vienna on a given day, against under 5% in January–March, June, September and November, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Smooth Snake sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Smooth Snake sightings, Vienna ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Budapest (Hungary, about 10%) and Prague (Czechia, about 10%).
Same family: Colubridae
The closest relatives of the Smooth Snake that you can see in Vienna (family Colubridae, Colubrid Snakes) are Aesculapian Snake (about 30%), grass snake (about 20%) and Tessellated Water Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Smooth Snake is recorded against all the reptiles logged in Vienna (23 verified sightings), 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.
