Australasian Reed-warbler Acrocephalus australis

Current view: Data table and detailed info

Taxonomy

Taxonomic note
Acrocephalus australis previously (del Hoyo and Collar 2014) included populations from Indonesia to Solomons comprising four subspecies (siebersi, harterti, celebensis and lentecaptus), but these have been transferred to A. stentoreus based on unpublished genetic evidence (Per Alström, per WGAC), although the position of celebensis is less clear. The species has been considered a subspecies of A. stentoreus, but molecular analysis supports treatment as separate species. Four subspecies recognised.

Population justification: The global population size has not been quantified, but the species is described as locally abundant (del Hoyo et al. 2006) and this is reinforced by citizen science data (eBird 2022).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
