(noun) A type of diving duck with a slender, narrow build and a long, thin, serrated bill that is slightly hooked at the tip. These ducks eat fish, frogs, mollusks and aquatic insects, and the serrated bill helps them strain water as they feed. Most merganser species are also crested, though the crests may be indistinct and can be raised and lowered, making them difficult to see in the field.
Species of merganser include common, hooded, red-breasted, Chinese and Brazilian mergansers.
