Population justification: It is described as rare to locally common (Bostwick 2020). It is more or less common in Córdoba, where the major global stronghold is protected by the Bañados del Río Dulce and Laguna de Mar Chiquita Natural Park, and frequent in Santiago del Estero. The population size has not been estimated directly, but is suspected to number at least 10,000 individuals (BirdLife International 2012), which roughly equates to 6,700 mature individuals. The population size is here placed in the band 6,700 - 19,999 mature individuals. The subpopulation structure is not known, but the species is highly mobile and so it is assumed to function as a single subpopulation.

Trend justification: The population is inferred to be in decline owing to ongoing habitat destruction for agricultural conversion.
