A rough distribution of the taxa within the species complex

The white-browed shrike-babbler (Pteruthius aeralatus) is a bird species found in the eastern Himalayas and Southeast Asia from northern Burma to southern Cambodia. Like others in the genus it is found in montane forests. Males and females have different plumages and variations occur through its range with several populations being treated as subspecies. It is part of a cryptic species complex and was earlier lumped as a subspecies of the white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler.

The white-browed shrike-babbler is sexually dimorphic. There are many variations between the populations and some are more distinctive than others but they may not be easy to diagnose in the field. In general appearance it is very similar to the Himalayan shrike-babbler but all subspecies with the exception of validirostris have the tertials of males partly coloured rufous and partly fulvous.

The common name commemorates Edward Blyth (1810–1873), who published the description and notes based on Samuel Tickell's specimen. It was earlier called Tickell's shrike-Tit.[2]

Taxonomy

The species was described by Edward Blyth who credited the name to collector Captain Samuel Tickell.[3] This and several other species were later lumped together as subspecies of Pteruthius flaviscapis.[4][5] In 2008, a molecular phylogenetic study resulted in the separation of species within the flaviscapis group with a large number split by application of the phylogenetic species concept and these were reorganized with a smaller number of species resulting in the following subspecies being included within white-browed shrike-babbler.[6][7]
