The Harlequin Duck — Cosmonetta Histrionica (Linnæus)
Iceland is the nearest breeding resort of this species, which nests also in Eastern Siberia, and only three or four examples have occurred on our coasts.
It is a very peculiarly marked Duck; the general colour above is bluish black, with a white spot at the base of the bill and behind each ear; a white line runs backwards over the crown, and another down the sides of the neck. A white ring, bordered with black, encircles the lower neck, and there is another similar one across the breast; the under parts are dark greyish brown. Length 17 in.; wing 8 in.
