HOODED MERGANSER

The smallest of our mergansers, Hoodeds are 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. The Hooded Merganser is one of the fastest-flying of our ducks. They mainly feed on small fish, which they pursue in long, rapid, underwater dives, but also take small frogs, newts, tadpoles, and aquatic insects.
