Discussion

The smallest of our mergansers, Hoodeds are most often seen along rivers and in estuaries during the fall and winter. They are usually found in pairs or in flocks of up to a dozen; when startled, they are among the fastest-flying of our ducks. Males perform a beautiful courtship display and, once mated, swim energetically around the female in further ritual displays. Hoodeds feed chiefly on small fish, which they pursue in long, rapid, underwater dives, but also take small frogs, newts, tadpoles, and aquatic insects.

Nesting

8-12 white eggs in a down-lined cup in a natural tree cavity or sometimes in a fallen hollow log.
