On 7 May 2012 a second-year Ring-billed Gull Larus

delawarensis was observed in flight near the south western

limit of the Celtic Sea at 48° 27’N 09° 11’W at 14.07 GMT(about 330 km south of Ireland). This gull was encountered only once during afive-day offshore cetacean survey between 6 and 10 May 2012. Throughout the monitoring period, two observers were on watch for a combined total of 130 hours. The Ring-billed Gull approached to 5 m and followed the vessel for a period of about two minutes before heading out to sea. The gull was accompanied by Gannets Morus bassanus, which were the only other bird species seen circling and following the vessel regularly.
