Taxonomic note
Subspecies rosselianus, previously included in this species (del Hoyo and Collar 2014), has been transferred to A. fasciatus following Schodde (2015), hence this is a new species concept. Emendation of original species name to cirrhocephalus not justified. Traditionally thought to be closely related to A. erythrauchen, and these two generally considered to form a species-group with A. brachyurus and possibly A. rhodogaster. Recent phylogenetic analyses, however, suggested possible close relationship of present species with A. gularis and A. virgatus (Breman et al. 2013). Birds of N Australia sometimes recognized as subspecies quaesitandus, but regarded as doubtfully valid. Two subspecies recognized.

Population justification: The population size of this species has not been estimated but its range spans a vast area wherein it is quite common (eBird 2022).

Trend justification: Forest loss in this species' range is minimal, equivalent to less than 1% in the three generations to 2021 (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Given this species' tolerance of, and perhaps predilection for, degraded habitats, forest cover loss is not currently thought to be causing an ongoing reduction in population size. In the absence of other threats thought capable of causing ongoing declines, the population trend is suspected to be stable.
