Taxonomy

Taxonomic note
Nothura chacoensis has been lumped into Nothura maculosa after Hayes et al. (2018) determined that there is no support for the former as an independent species.

Population justification: The global population size has not been quantified, but this species is described as common (Stotz et al. 1996).

Trend justification: This species is one of the most common tinamous. Its range is currently expanding owing to deforestation and agricultural conversion. Despite being a popular sporting bird, effective hunting controls exist in much of its range and high reproductive potential means it is able to tolerate present hunting levels (del Hoyo et al. 1992). However, the shift towards more intensive arable production and the expansion and intensification of grazing and row crop practices is leading to a decline in suitable habitat for this species and it has become increasingly scarce throughout a significant proportion of its range as a result (Thompson and Carroll 2009). A slow population decline is therefore suspected.
