Taxonomic note
Myrmothera campanisona and M. subcanescens were formerly lumped as M. campanisona (del Hoyo and Collar 2016), but are now split on the basis of genetic divergence and differences in voice (see under T. subcanescens). Five subspecies recognised.

Population justification: The population size has not been quantified, but the species is described as 'fairly common' (Stotz et al. 1996).
Trend justification: Despite its preference of edge and disturbed habitat it is suspected that slow declines are ongoing due to the loss and fragmentation of forests and subsequent decline of its insect prey (Greeney 2020). Tree cover loss within the range is low (3% over three generations; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely equally low; they are here tentatively placed in the band 1-9% over three generations.
