Taxonomic note
Automolus ochrolaemus, A. exsertus and A. cervinigularis were previously lumped as A. ochrolaemus (del Hoyo and Collar 2016), but are split on the basis of genetic divergence (Smith et al. 2014, Schultz et al. 2017) and differences in vocalisations, confirmed by playback experiments (Freeman and Montgomery 2017). Some signs of introgression between auricularis and nominate in W Brazil. Four subspecies recognized.

Population justification: The population size has not been quantified given recent taxonomic splits. However, based on the frequency of observations within the extremely large range (per eBird 2023) the population is likely large.

Trend justification: The population trend has not been investigated. Tree cover within the range is lost at a rate of 3% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). The species however also occurs near treefall gaps, in secondary growth and in fragmented forest, and vast areas of pristine habitat remain within the range (Remsen Jr. and Greeney 2020, Global Forest Watch 2023); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, even though the population may decline locally (see Pollock et al. 2022), the population is currently suspected to be stable.
