Population justification: Given the scarcity of recent sightings, the population is thought to number fewer than 250 mature individuals (A. Kirkconnell in litt. 2009, A. Mitchell in litt. 2009), and so is placed in the band 50-249 mature individuals, a range similarly estimated between 2000-2008 by Wetlands International (2020). This equates to 75-374 individuals in total, rounded to 70-400 individuals here.

Trend justification: The paucity of recent records and anecdotal evidence suggest that there has been a significant decline since the year 2000, though the rate of decline is unknown (A. Kirkconnell in litt. 2009; A. Mitchell in litt. 2009). Surveys are required to confirm this decline, though declines have been noted in resident Spotted Rail Porzana maculatus and King Rail Rallus elegans as well as migrant Sora P. carolina (A. Mitchell in litt. 2012).
