影音備註
First-cycle Iceland (THGU) Gull. Note the dark brown primaries with pale edges -- typical of first-cycle THGU, and the bill with some pink coloration in the proximal half. An American Herring Gull (AHGU) would typically have more pink in the bill at this date, as well as the primaries would be more black with little or know pale edges. Also note the bill is slightly less deep that the bill of the GWGU in this list. All four of the photos are of the same individual.
