Wilson's Phalarope (Phalaropus tricolor) lives in prairie wetlands across North America. It feeds on insects and crustaceans. Its conservation status is Least Concern.
Fascinating facts about the Wilson's Phalarope
- At about 23 cm in length, Wilson's phalarope is the biggest member of its family, out-sizing the red phalarope. It breeds on the prairie wetlands of western Canada and the western United States, preferring the open grass-land habitats of the North American prairies. The species is a small wader, yet its size makes it the largest of the phalaropes, a distinction noted by its slightly longer body compared with its relatives.
- Wilson's phalaropes are unusually halophilic, thriving on salty water where they gather in huge flocks during migration. They feed in great numbers on inland saline lakes such as Mono Lake in California, Lake Abert in Oregon and the Great Salt Lake of Utah, often alongside red-necked phalaropes. These salt-rich sites provide abundant insects and crustaceans, supporting the species' preference for halophilic habitats throughout its migratory journey.
- When hunting, a Wilson's phalarope swims in a small, rapid circle that creates a miniature whirlpool, a technique that lifts prey from the bottom of shallow water. This behaviour is thought to aid feeding by raising insects and crustaceans into the vortex. The bird then reaches into the outer edge of the whirlpool with its fine black bill, snapping up the small organisms that have been drawn up, allowing efficient foraging in the water column.
- Wilson's phalanrope occasionally turns up in western Europe, but such sightings are exceptional because the bird normally breeds on the North American prairies and spends the non-breeding season far to the south. It migrates across the continent, passing through Central America in spring and autumn, before wintering on inland salt lakes near the Andes in Argentina.
