Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion. Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
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).
It occurs in Argentina, Uruguay, Paraguay, Brazil, and Bolivia. It disperses after breeding, appearing further south in Argentina during the non-breeding season (Kear 2005, Carboneras and Kirwan 2020).
It occurs in swampy tropical forests and marshy clearings in well-wooded lowlands, secluded pools, small streams and rice paddies (Kear 2005, Carboneras and Kirwan 2020). It requires flooded forests with tree holes for breeding (Kear 2005).
