Rare
Under 5% of wildlife watchers report a European Beak sighting in Madrid on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 457 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.
April
In that month about 10% of wildlife watchers report a European Beak in Madrid on a given day, against under 5% in May to March, 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.
7th of 7
Of the 7 cities where we can rate European Beak sightings, Madrid ranks 7th at under 5%. The best odds are in Budapest (Hungary, about 10%), Turin (Italy, about 10%) and Barcelona (Spain, about 10%).
Same family: Nymphalidae
The closest relatives of the European Beak that you can see in Madrid (family Nymphalidae, Brush-footed Butterflies) are Speckled Wood (about 20%), Painted Lady (about 20%) and Red Admiral (about 20%), 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 Madrid (6 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.
