Key Field Marks
- Medium-sized diving duck (about 42–50 cm) with a distinctively large, angular head shape and a short bill
- Male: glossy dark green head (can look black in poor light) with a round white spot between the eye and the bill base, bright golden-yellow eye, clean white body, black back
- Female: chocolate-brown head, gray body, often with a white collar-like band around the neck, dark bill usually tipped with yellow-orange, and a yellow eye
- Bold black-and-white wing pattern visible in flight in both sexes
How to Tell It Apart from Similar Species
- Barrow's Goldeneye: male shows a crescent-shaped (not round) white facial patch and a purple (not green) gloss on the head, along with more extensive black spotting along the flanks and scapulars; female Barrow's Goldeneye has a more orange or all-yellow bill and a steeper forehead with a stubbier bill profile
- Bufflehead: much smaller overall, and the male shows a large white patch covering most of the back of the head rather than a small round spot near the bill
Habitat, Range & Season
- Breeds across the boreal forest zones of North America, Europe, and Asia, nesting in tree cavities near lakes and rivers
- Winters on larger lakes, rivers, and coastal bays farther south, often in mixed flocks with other diving ducks
Voice
- Generally a quiet species; males give a soft, nasal call during courtship displays
- The wings produce a distinctive loud whistling sound in flight, which has earned the bird the nickname "whistler" among waterfowl hunters and birders alike
Behavior Notes
- Dives underwater to feed on aquatic invertebrates, small fish, and plant material
- Flies with rapid, direct wingbeats, and the whistling wing sound often reveals its presence before it is seen
Frequently asked questions
How do I tell Common Goldeneye from Barrow's Goldeneye?

Why is Common Goldeneye nicknamed the 'whistler'?
Its wings produce a loud, distinctive whistling sound in flight, often audible before the bird is seen, which has given rise to this common nickname.
Where does Common Goldeneye nest?
It nests in tree cavities, including old woodpecker holes, near lakes and rivers within the boreal forest zones of North America, Europe, and Asia.
What does a female Common Goldeneye look like?
A female has a chocolate-brown head, gray body, often a whitish neck collar, a dark bill typically tipped in yellow-orange, and a yellow eye — lacking the male's glossy green head and white cheek spot.
