- Harlequin Ducks Bathing and Feeding shows them bathing by a method termed "Splash-Bathing" (splashing water on to body by lowering wings and flapping quickly)
- It also shows them feeding underwater by turning over stones and grabbing what lives under them.
- Diet is entirely animal. On breeding grounds, takes young and adult aquatic insects and fish roe (Bengtson 1972a, Dzinbal and Jarvis 1984, Cassirer and Groves 1994). On wintering grounds, takes intertidal and subtidal marine invertebrates, especially crabs, amphipods, and gastropods, to depth of 10-20 m; occasionally small fish and fish roe (Palmer 1949, Vermeer 1983a, Goudie and Ankney 1986, Gaines and Fitzner 1987, Fischer 1998a).
