Taxonomic note
Populations from Indonesia to Solomons comprising four subspecies (siebersi, harterti, celebensis and lentecaptus) previously included in A. australis (del Hoyo and Collar 2014) have been transferred to A. stentoreus based on unpublished genetic evidence (Per Alström, per WGAC), although the position of celebensis is less clear. Species has often been considered conspecific with A. australis. Hybrids between present species and A. arundinaceus described from S Kazakhstan (Hansson et al. 2012). Somewhat larger and darker birds from Levant, currently included in nominate subspecies, sometimes separated as subspecies levantinus. Eight subspecies recognized.

Population justification: The global population size has not been accurately quantified, but the species is described as common to abundant in much of its range (del Hoyo et al. 2006). Densities of 10-20 singing birds/ha in the Nile Delta, Egypt, suggest more than 100,000 breeding pairs there (Snow and Perrins 1998) and densities seem similarly high through much of its range (Kennerley and Pearson 2010).
Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
