Population justification: The total population has not been quantified. Even at known sites numbers are low and the species appears to be scarce (R. Clay in litt. 2024). The population is suspected to number less than 10,000 mature individuals, perhaps not substantially more than 1,000 (Galluppi-Selich et al. 2018). Preliminarily, the population is here placed in the band 2,500-9,999 mature individuals, though an accurate quantification is urgently required.

Trend justification: The global population trend has not been directly quantified. The species is locally abundant in Iberá National Park and this population may be increasing: an analysis of eBird data show an increase in reporting rate probability in the period 2014-2019 (Turbek et al. 2021). However, this species remains poorly understood overall and its breeding and non-breeding grounds, migratory routes and the threats throughout the full annual cycle have not been conclusively identified. Precautionarily, declines are suspected on the basis of habitat loss and degradation within the range through conversion of grasslands to agricultural areas, afforestation, overgrazing, burning/wildfires, replacement of native pastures by exotic grasses and water abstraction from wetlands, as well as potentially capture for trade (A. Di Giacomo in litt. 2016, Galluppi-Selich et al. 2018, Browne et al. 2021, Di Bitetti et al. 2022, R. Clay in litt. 2024, A.P. Nunes in litt. 2024).
