WILSON'S PHALAROPE


Phalaropus tricolor


Description:

Unlike most birds, the Wilson's Phalarope female is flashier and brighter plumaged than the male. The phalarope genus name, Phalaropus, means "coot-footed" and was inspired by the phalarope's feet which are adapted for swimming. Two of the phalarope species winter at sea and have semipalmate (partially webbed) feet with lobed toes, while the more terrestrial Wilson's Phalarope has flanged toes.
