Meaning
A fish-eating diving duck with a slender, serrated beak.
Any of several species of diving ducks belonging to the genus *Mergus* or *Lophodytes*, characterized by a thin, hook-tipped bill with saw-like edges for gripping fish. They are often associated with clear, fast-flowing rivers and coastal waters.
Linguistics
Semantic Notes
The term is primarily a zoological/birdwatching term. In everyday language, it is often replaced by the more general 'duck' or the more specific common name of a species (e.g., 'goosander'). The serrated beak is its defining feature.
Dialectal Variation
British vs American Usage
Differences
The species *Mergus merganser* is called 'Goosander' in British English and 'Common Merganser' in American English. *Mergus serrator* is the 'Red-breasted Merganser' in both.
Connotations
Neutral scientific/ornithological term in both. More likely to be known and used by birdwatchers and naturalists.
Frequency
Equally rare in general use in both varieties. Slightly higher recognition in North America due to the presence of 'Hooded Merganser' (*Lophodytes cucullatus*), a popular bird among wildlife enthusiasts.
