Discussion Among
goldeneyes pair formation begins in midwinter, and until then the two sexes
often form separate flocks. Indeed, male Common Goldeneyes winter farther north
than do the females. During its courtship display, the male stretches his head
forward along the water and then snaps it rapidly upward over his back, bill
pointed skyward, while uttering a shrill, two-noted call. Then he swings his
orange feet forward, sending up a small shower in front of him. The wings of
this species produce a loud whistling sound in flight, easily identified even
when the birds cannot be seen; hunters call this species the
"Whistler." Goldeneyes can dive to depths of 20 feet (6 meters) or
more, but generally limit themselves to about 10 feet (3 meters). In winter,
goldeneyes feed mainly on mollusks; in summer, their diet shifts to aquatic
plants and insects.
