The Common Merganser prefers to breed in ponds associated with upper portions of rivers in forested regions, and clear, freshwater lakes with forested shorelines. It winters as far north as open inland waters are available. The Common Merganser generally nests in cavities in hollow trees near water, but also in dark recesses, on the ground or in nest boxes. The height of the tree cavity and species of tree are unimportant, but the number of suitable cavities available is definitely limited.
