With luck
About 10% of wildlife watchers report a Large Tabby sighting in Vienna on a given day, based on 62 verified sightings from GBIF citizen-science data. It is the 251st most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Large Tabby in Vienna on a given day, against under 5% in July to April, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Large Tabby sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 29 cities where we can rate Large Tabby sightings, Vienna ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Helsinki (Finland, about 10%) and Seattle (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Tabby is recorded against all the insects logged in Vienna (62 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.
