The Eyes of Common Goldeneyes

3-31-14 lone common goldeneye on ice 380Common Goldeneyes, birds of the boreal forest, overwinter as far north as open water permits, which includes parts of northern New England most years. These birds get their common name from the color of their eyes, but their eyes don’t attain this golden color until their first winter. When they hatch, Common Goldeneye ducklings have gray-brown eyes. Their eyes turn purple-blue, then blue, then green-blue as the ducks age. By the time they are five months old, their eyes are pale green-yellow. They turn bright yellow in males and pale yellow to white in females by mid-winter.
