With luck
About 10% of wildlife watchers report a European Beak sighting in Barcelona on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 146th most-seen of the 381 insects 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.
February–June and August
In those months about 10% of wildlife watchers report a European Beak in Barcelona on a given day, against under 5% in July and September–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most European Beak 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 7 cities where we can rate European Beak sightings, Barcelona ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Budapest (Hungary, about 10%) and Turin (Italy, about 10%).
Same family: Nymphalidae
The closest relatives of the European Beak that you can see in Barcelona (family Nymphalidae, Brush-footed Butterflies) are Painted Lady (about 30%), Red Admiral (about 30%) and Speckled Wood (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Beak is recorded against all the insects logged in Barcelona (21 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.
