It was a Larus gull for sure, and not a Common Gull. The call that drew my attention was a very distinctive nasal 'EH'. BirdNET suggested Lesser Black-backed Gull with rather low confidence, but when I listened to its calls, they sounded spot on. The gull was flying away already when I managed to press the record button, so the calls are trailing away a bit. Thanks in advance!
BTW, is gulling by ear even a thing (and what about the calls of hybrids, particularly Herring x Caspian Gull)?
