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.
