  • The male's vibrant rosy bill features a prominent fleshy knob at the base that intensifies in color during breeding.
  • It is the most abundant diving duck in South America, often congregating in flocks of several thousand individuals.
  • Unlike many northern pochards, it lacks a distinct eclipse plumage, maintaining its bright colors throughout the year.
  • The species exhibits strong flight capabilities, marked by a conspicuous broad white stripe across the primary and secondary feathers.
Habitat
Shallow freshwater marshes, lagoons, and lakes with abundant floating and emergent vegetation.

Southern South America, including Argentina, Chile, Uruguay, Paraguay, and southern Brazil.
