The Italian crested newt (Triturus carnifex) is a species of newt in the family Salamandridae. Triturus carnifex is found in parts of the Balkans and Italy. It is an aquatic breeder that can spend up to four months in the water. The location of the ponds where they breed affects the time when T. carnifex enters the water. T. carnifex prefers living in deep water since it is a nektonic species: it swims freely and is independent of currents. The absence of predatory fish may also explain why T. carnifex is inclined to ponds, rather than other larger bodies of water.
They typically prefer ponds in northern Europe, where temperatures are colder. Adult T. carnifex start to arrive between February and May, and leave between July and October. In warmer ponds, adult newts arrive within a month and leave during a two-week period in July. Andreone and Giacoma (1989) speculated that newt migration into the ponds increases after rainy days, since after rainfall, newt activity is not limited by humidity.
Higher altitudes, where temperatures begin to decrease, have a direct effect on the size of T. carnifex. Ficetola et al. (2010) discovered that living in colder temperatures resulted... Wikipedia →

Rare
Under 5% of wildlife watchers report an Italian Crested Newt sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March and September–October
In those months about 10% of wildlife watchers report an Italian Crested Newt in Vienna on a given day, against under 5% in April–August and November–February, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Italian Crested Newt sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Salamandridae
The closest relatives of the Italian Crested Newt that you can see in Vienna (family Salamandridae, True Salamanders and Newts) are Smooth Newt (about 20%), Fire Salamander (about 20%) and Alpine Newt (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Italian Crested Newt is recorded against all the amphibians logged in Vienna (8 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.
