Steganopus tricolor

The Wilson's phalarope (Phalaropus tricolor) is a small wader. This bird, the largest of the phalaropes, breeds in the prairies of North America in western Canada and the western United States. It is migratory, wintering in inland salt lakes near the Andes in Argentina. They are passage migrants through Central America around March/April and again during September/October. The species is a rare vagrant to western Europe.

This species is often very tame and approachable. Sometimes it is placed in a monotypic genus Steganopus.

This bird is named after Scottish-American ornithologist Alexander Wilson. The English and genus names for phalaropes come through French phalarope and scientific Latin Phalaropus from Ancient Greek phalaris, "coot", and pous, "foot". Coots and phalaropes both have lobed toes. The specific tricolor is from Latin tri-, "three-", and color, coloris "colour".

Wilson's phalarope is slightly larger than the red phalarope at about 23 cm (9.1 in) in length. It is a dainty shorebird with lobed toes and a straight fine black bill. The breeding female is predominantly gray and brown above, with white underparts, a reddish neck and reddish flank patches. The breeding male is a duller version of the female, with a brown back, and the reddish patches reduced or absent. In a study of breeding phalaropes in the province of Saskatchewan, Canada, females were found to average around 10% larger in standard measurements and to weigh around 30% more than the males. Females weighed from 68 to 79 g (2.4 to 2.8 oz), whereas males average 51.8 g (1.83 oz).
