Common Goldeneye

Common Goldeneyes are cavity nesters, meaning they build their nests in hollow trees, typically located in the mature northern forests of North America and Eurasia. They often use old woodpecker holes, particularly those made by Pileated Woodpeckers. Because they rely on tree cavities, they will also readily use artificial nest boxes if provided.

The Common Goldeneye is known for the distinct, whistling sound its wings make during flight, which is why it is sometimes called the 'Whistler.' Male ducks also produce a variety of mechanical, clicking sounds during courtship displays, throwing their heads back dramatically. Females generally make a harsh, grating 'scaup' call when communicating with their young.

Adult male Common Goldeneyes are distinguished by their iridescent dark green heads, bright yellow eyes, and contrasting black-and-white bodies. Females, on the other hand, have a brown head, a gray body, and a distinct white wing patch. Females also typically have a yellow tip on their dark bill, whereas the male's bill is solid black.

Shortly after hatching, Common Goldeneye ducklings leap from their tree cavity nests to the ground or water below. They are highly precocial and immediately begin feeding on small aquatic invertebrates, insects, and crustaceans. As they mature and become accomplished divers, they shift their diet to include larger prey like small fish and crabs found in northern lakes and coastal waters.
