Rare
Under 5% of wildlife watchers report a Forked Tabby sighting in Vienna on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 895th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Forked Tabby in Vienna on a given day, against under 5% in September to July, the lowest months. That is one of Vienna's wettest months, with about 85 mm of rain against 40 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Forked Tabby sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 4 cities where we can rate Forked Tabby sightings, Vienna ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Hamburg (Germany, under 5%), Munich (Germany, under 5%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Forked Tabby is recorded against all the insects logged in Vienna (10 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.
