Black-headed Gull

Hi Jonah, I'm no expert but I'll try to explain and I am open to correction. Neither name is incorrect but the latest scientific name for the Black-headed Gull is Chroicocephalus ridibundus. This is the name given by the RSPB but you will see Larus ridibundus as the iSpot default and in some books and guides.

As a rule I would always go for Chroicocephalus ridibundus on iSpot otherwise you will be corrected and lose the credit for your identification. There has been much debate about this recently and it is a current bone of contention. I hope that assists.
