Good Morning Mr. Goldeneye!
Golden Eyes (Bucephala clangula) are cousins of Buffleheads (Bucephala albeola). The genus name Bucephala is derived from the Ancient Greek boukephalos (“bullheaded”, from bous, “bull ” and kephale, “head”), a reference to the bird’s bulbous head shape. Males of both species deploy ‘look-how-handsome-I-am-with-my-head-puffed-behavior’ during the courtship dance, a feature the females appear to find irresistible. Along the Goldeneye’s coastal wintering grounds they feed mostly on crustaceans, small fish, mollusks, and sea vegetation.
A fun fact about Goldeneyes – the eyes are brownish gray at hatching, then turn purple-blue, then blue, then green-blue as they grow. By five months of age they have become clear pale green-yellow. The eyes eventually become golden yellow in adult males and pale yellow to white in females.
