Common Goldeneye

Breeds on lakes, ponds, and marshes, and winters on inland lakes and rivers or coastal bays and nearshore waters. Very similar to Barrow’s Goldeneye. Males are easiest: Common has less black on the back, lacks a dark spur on the side, and has a circular (not crescent-shaped) white patch on the face. Females can be very difficult. Common usually has a dark bill with a small yellow patch near the tip, but rarely can have an entirely dull yellowish bill like Barrow’s. Head and bill shape are important: Common has more evenly rounded head with a peak in the center of the crown, and a longer, straighter-edged bill.
