Eggs are from 61.2 to 66.6 grams. Females lay 1 egg every other day. (Eadie, et al., 1995) Common goldeneyes nest in tree cavities, but will accept nest boxes and occasionally are found in rock cavities. Females find nest cavities and line them with a nest bowl constructed of other materials and downy feathers.
Common goldeneyes are aggressive and territorial ducks and have elaborate courtship displays. They usually breed between December and May. The birds nest in cavities in large trees, where they return year after year, though they will readily use nest boxes as well. The female lays 4-9 eggs and the incubation period ranges from 28 to 32 days.
