觀察細節
Adult molting into winter plumage. Thinner bill than expected for most Forster's Terns. Incomplete black crown with white forehead - no black earpatch forming like on winter Forster's. Black outer primaries with darker black wedge going in from the trailing edge around p5-6. Dark carpal bar just starting to become evident along leading edge of wings in flight. Backlit views also showed a translucent patch on inner primaries (see pic with sunlight coming through).
