|Taxonomic Notes:||Rallus longirostris, R. crepitans and R. obsoletus (del Hoyo and Collar 2014) were previously lumped as R. longirostris following AOU (2000). 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.

This species has a very 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to 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:||The population is estimated to number over 20,000 individuals (Wetlands International 2014).|
Trend Justification: The overall population trend is decreasing owing to conversion of its mangrove and wetland habitats (G. Kohler in litt. 2014).
|Current Population Trend:||Decreasing|
