The common Goldeneye is a bird of the diving duck family. The appearance of the male differs quite noticeably from the female. The male has a teal green head with a large white spot on the lore. The body is black on the back and white on the bottom with barring where the two colors meet. The bill is black and the feet are a brilliant orange. The eye is a golden yellow or orange.(Sibley, 2003)

The female is less striking in appearance. It has a plain brown head with a white stripe at the bottom of the neck. Its back is grey with black wings and white secondaries. Its eyes and feet are the same as the males, but its beak is black with yellow at the tip.(Sibley, 2003)
