  
Common goldeneyes are most abundant among lakes of the Canadian boreal forests, especially where lakes or deep marshes have substantial invertebrate populations. They are cavity nesters and have a strong homing tendency, often using the same cavity in successive years. Nests are usually located near a pond, lake, or river, but may be found in woodlands up to a mile from water. Female common goldeneyes nest in natural tree cavities, abandoned woodpecker holes, or nest-boxes and lay an average of 9 eggs.
