Wilson’s Phalarope

Phalaropes reverse the usual sex roles in birds: Females are larger and more colorful than males; females take the lead in courtship, and males are left to incubate the eggs and care for the young. Wilson's Phalarope is an odd shorebird that swims and spins on prairie marshes. The other two species of phalaropes nest in the Arctic and winter at sea, but Wilson's is a bird of inland waters, nesting mostly on the northern Great Plains. Huge numbers may gather in fall on some salty lakes in the west, such as Mono Lake and Great Salt Lake, before migrating to South America.
