Population justification: It is not considered to be particularly rare (Carboneras and Kirwan 2020). It is common in small numbers across much of its range, with 800–1,000 counted during a census in Bañados de Figueroa, Argentina (Kear 2005). The population size is suspected to fall within the range 25,000 - 100,000 individuals (Wetlands International 2021).

Trend justification: Remote sensing data on tree cover loss indicate that approximately 14% of tree cover with at least 30% canopy cover was lost from within the species's range over three generations (16 years) from 2003 to 2019 (Global Forest Watch 2021). Extrapolating forwards and assuming the rate of forest loss remains stable, 17% of tree cover is projected to be lost from the species's range over the next three generations. Although the species does not occur solely in forests, it requires flooded forests with tree holes for breeding (Kear 2005). The species's population size is therefore suspected to be declining at a rate of 10-19% over three generations (16 years).
