觀察細節
**Late**. Large diving duck with rounded head (peaked at rear crown in LESC) with well defined white around the base of the bill in hens. Hen appears uniformly brown. In summer hens often show a white cheek patch (more so than LESC) as seen in the attached photographs I took. This hen was spending time in the south eastern most part of the harbor.
