Rare
Under 5% of wildlife watchers report a Mediterranean Gull sighting in Wadden Sea National Park on a given day, based on 276 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 155th most-seen of the 285 birds 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–May and July
In those months about 10% of wildlife watchers report a Mediterranean Gull in Wadden Sea National Park on a given day, against under 5% in June and August–March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mediterranean Gull sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 9
Of the 9 parks where we can rate Mediterranean Gull sightings, Wadden Sea National Park ranks 5th at under 5%. The best odds are in Kiskunság National Park (Hungary, about 20%), Camargue (France, about 20%) and Fertő-Hanság National Park (Hungary, about 10%).
Same family: Laridae
The closest relatives of the Mediterranean Gull that you can see in Wadden Sea National Park (family Laridae, Gulls, Terns, and Skimmers) are Black-headed Gull (about 70%), European Herring Gull (about 70%) and Common Gull (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mediterranean Gull is recorded against all the birds logged in Wadden Sea National Park (276 verified sightings from 2019 to 2026), 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.
