Common Merganser Seasonal Range

Habitat

Lakes and rivers bordered by forests mature (conifer or mixed) enough to provide nesting cavities (Mallory and Metz 1999) and in mountainous terrain (AOU 1983, Terres 1980). Northern limit of breeding range follow limit of open boreal forest (Palmer 1976, Haapanen and Nilsson 1979, Bellrose 1980). Females move broods downstream to larger rivers, lakes, or bays (White 1957, Erskine 1972, Wood 1985, McNicol et al. 1995). In B.C., breeds on marine shores at sea level to mountainous regions up to 1,000 m in elevation (Campbell et al. 1990).
