Taxonomic note
Rallus elegans and R. tenuirostris (del Hoyo and Collar 2014) were previously lumped as R. elegans following AOU (2000). Sibley and Monroe (1990, 1993) included tenuirostris within R. longirostris.

Population justification: The population size is currently estimated to total ~15,000 mature individuals (Partners in Flight 2019).

Trend justification: The population is suspected to be declining owing to the degradation of its wetland habitat.
