This is a monotypic species[1].

Formerly often included in the genus Tringa, but genetic evidence shows it to be more closely related to Phalaropes Phalaropus[2].

[edit] Habitat

Breeds beside muddy or gravelly riversides and lakeshores; typically nesting among greyed driftwood on riverbanks. On migration on freshwater marshes. In winter, coastal mudflats, estuaries and mangroves.

[edit] Behaviour

[edit] Diet

Food is small aquatic invertebrates; it chases insects and other mobile prey, and sometimes runs to the water's edge to wash its catch.
