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.
Description
Image: Blyth’s_Shrike-Babbler.tif
File:Pteruthius aeralatus Keulemans.jpg
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.{{cite book|page=333|title=The Fauna of British India, including Ceylon and Burma. Birds. Volume 1|edition=2|author=Baker, E.C.

Taxonomy
The species Pteruthius aeralatus was described by Edward Blyth who credited the name to collector Captain Samuel Tickell.{{cite journal|url=https://www.biodiversitylibrary.org/page/40268561|author=Blyth, E.|journal=Journal of the Asiatic Society of Bengal|volume=24| year=1855| title=Report of the Curator, Zoological Department, for April Meeting, 1855|pages=252–281}} This and several other species were later lumped together as subspecies of Pteruthius flaviscapis.{{cite book|title=The Fauna of British India, including Ceylon and Burma.
