Worldwide Species Action Plans

Wilsons Phalarope action planWilsons Phalarope (Phalaropus tricolor) is a medium-size shorebird best known for congregating in huge, post-breeding flocks at a few sites in North America and for its reversed sexual dimorphism, with females being more colorful than the males. Unlike the two other phalarope species [Red Phalarope (P. lobatus) and Red-necked Phalarope (P. fulicarius)], Wilson?s Phalarope is a temperate breeder (as opposed to having a holarctic breeding distribution) and does not winter at sea. The species is confined to the Americas where it breeds in central Canada and the United States and winters primarily on saline lakes in the Andes of South America and the Southern Cone lowlands.
