When feeding, a red-necked phalarope will often swim in a small, rapid circle, forming a small whirlpool. This behaviour is thought to aid feeding by raising food from the bottom of shallow water. The bird will reach into the center of the vortex with its bill, plucking small insects or crustaceans caught up therein. On the open ocean, they are often found where converging currents produce upwellings. During migration, some flocks stop over on the open waters at the mouth of the Bay of Fundy to take advantage of food stirred up by tidal action.
