Etymology: The scaup is named for a shellfish bed. Its etymology points to "scalp," a word for a bed of oysters or mussels, and the link lies in the bird's habit of feeding on the mollusks and other small creatures that gather in such beds. Early English speakers who watched these ducks working over shellfish grounds applied the name of the seabed to the birds that fed there. The word is therefore a case of a place-based or food-based name transferring from the shellfish to the bird that hunts them. Its meaning moved from the bed itself to the duck, so the bird is named for the bottom it feeds on rather than for anything about its own appearance or voice.
