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 (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not 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
The global population is suspected to number 27,700-105,500 individuals (Wetlands International 2022), which roughly equates to 18,000-70,000 mature individuals.
Trend justification
The trend is difficult to determine. The species appears to be locally expanding its range (e.g. in Brazil; Martínez-Vilalta et al. 2020), while other populations are stable or have unknown trends (Wetlands International 2022). Precautionarily the overall population is assessed as being stable.
