There are colonies elsewhere in southern Europe, and this species has undergone a dramatic range expansion in recent decades. As is the case with many gulls, it has traditionally been placed in the genus Larus.

Rare
Under 5% of wildlife watchers report a Mediterranean Gull sighting in Amsterdam on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 132 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mediterranean Gull in Amsterdam on a given day, so our monthly data shows no clear season.
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.
22nd of 30
Of the 30 cities where we can rate Mediterranean Gull sightings, Amsterdam ranks 22nd at under 5%. The best odds are in Antalya (Turkey, about 20%), Algiers (Algeria, about 20%) and Casablanca (Morocco, about 20%).
Same family: Laridae
The closest relatives of the Mediterranean Gull that you can see in Amsterdam (family Laridae, Gulls, Terns, and Skimmers) are Black-headed Gull (about 60%), European Herring Gull (about 50%) and Lesser Black-backed Gull (about 40%), 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 Amsterdam (32 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.
