Rare
Under 5% of wildlife watchers report a Bird's Wing sighting in Vienna on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 426th 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 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Bird's Wing in Vienna on a given day, against under 5% in September to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Bird's Wing 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.
4th of 9
Of the 9 cities where we can rate Bird's Wing sightings, Vienna ranks 4th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Kyiv (Ukraine, about 10%) and Bucharest (Romania, under 5%).
Same family: Noctuidae
The closest relatives of the Bird's Wing that you can see in Vienna (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 20%), Large Yellow Underwing (about 10%) and Cotton Bollworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bird's Wing is recorded against all the insects logged in Vienna (31 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.
