Bucephala islandica (Barrow's Goldeneye) is a species of birds in the family Anatidae. They are listed as of special concern by COSEWIC. They are associated with freshwater habitat. They are native to the Palearctic and The Nearctic. They are diurnal herbivores. They have parental care (female provides care). They rely on swimming, drag powered swimming, and flight to move around.

Definition: Self-propelled movement of an organism from one location to another through water, often by means of active fin movement.

URI: https://eol.org/schema/terms/drag_based_swimming
Definition: Drag swimmers use a cyclic motion where they push water back in a power stroke, and return their limb forward in the return or recovery stroke. When they push water directly backwards, this moves their body forward, but as they return their limbs to the starting position, they push water forward, which will thus pull them back to some degree, and so opposes the direction that the body is heading. This opposing force is called drag. The return-stroke drag causes drag swimmers to employ different strategies than lift swimmers. Reducing drag on the return stroke is essential for optimizing efficiency.
