| 説明 | Adult hybrid of Herring Gull and Great Black-backed Gull. Larger than nearby Herrings. Quite like northern Western Gull (Larus occidentalis occidentalis) but reviewers beginning with Ethan Gyllenhaal noted streaked head, shorter bill, more white in wing tips than normal for that species. Observed with Dan Scheiman who considered Herring x LBBG possibility. Pink legs, bigger than Herrings, thick yellow bill.
