White-browed Shrike-babbler
Pteruthius aeralatus
红翅鵙鹛
Introduction
A bird species in the family Vireonidae found in the eastern Himalayas and Southeast Asia, ranging from northern Burma to southern Cambodia. Inhabits montane forests throughout its range. Exhibits strong sexual dimorphism with males and females having distinctly different plumages. Multiple populations show significant geographic variation, with several distinct subspecies described across its range. Part of a cryptic species complex that underwent taxonomic revision, having been previously lumped as subspecies of the white-browed shrike-babbler complex.
Description
A small passerine bird with marked sexual dimorphism. Males and females differ significantly in plumage coloration. Shows considerable geographic variation across populations, with some subspecies being more distinctive than others. The species is characterized by tertial feathers that are partly rufous and partly fulvous in color, though this varies by subspecies. The nominate subspecies P. a. aeralatus occurs in Burma and western Thailand.
Identification
Very similar in general appearance to the Himalayan shrike-babbler (Pteruthius ricketti). Field identification can be challenging due to plumage variations between subspecies and overlap with similar species. Male specimens of most subspecies (except validirostris) can be distinguished by their rufous and fulvous tertial coloration. The complex taxonomy and geographic variation make confident identification difficult in the field.
Distribution & Habitat
Occurs across the eastern Himalayas through Southeast Asia. Range extends from northern Burma and western Thailand east to southern Cambodia and southern Vietnam. Found in montane forest habitats throughout its distribution. Subspecies show distinct geographic patterns: ricketti in northeastern Burma to southeast China and Indochina; schauenseei in southern Thailand; cameranoi in the Malay Peninsula and Sumatra; robinsoni in Borneo; ripleyi from western Himalayas to central Nepal; and annamensis in southern Vietnam.

Culture
The common name commemorates Edward Blyth (1810–1873), who published the original description and notes based on specimens collected by Samuel Tickell. The species was earlier known as Tickell's shrike-Tit. Blyth described the species Pteruthius aeralatus in 1855, crediting the name to Captain Samuel Tickell.
