Sites reaching the 1% threshold (Ramsar Convention Criterion No. 6) are: Banhado do Capivari in Brazil and La Segua in Ecuador (34,494 birds).

 

Migration and seasonality

Migrates from central Argentina (Pampas and Chaco) to the wintering areas in Uruguay and southern Brazil, where they arrive in the autumn and leave in southward migration by the spring. Migration occurs along the central and eastern Argentina routes (link to Seasonality map).

 

Habitat

Lagoons and ponds, fresh-water marshes, lakes with rich vegetation and surrounded by woods, flooded savannas, swamps, flooded grasslands and rice fields.

 

Habits and interactions with human activities

Gregarious, sometimes in flocks of thousands and mixed with other duck species.
