Shrike Babbler
The shrike-babblers are a group of small birds in the genus ''Pteruthius''. They are native to the Indomalayan realm, and were traditionally placed in the family Timaliidae before molecular phylogenetics, molecular phylogenetic studies in 2007 found that they were best considered as belonging to the family Vireonidae which was then thought to be restricted to the New World. They were traditionally classified into five species with several subspecies but changes in the status of these species on the basis of the phylogenetic species concept suggest more forms in a cryptic species complex. Most species are found in montane forests, with some species bird migration, descending down to lower altitudes during the winter. The shrike-babblers range in size from 11.5–20 cm in length and weigh 10-48 g. They are divergent in plumage and size but all possess a stout black hooked bill, short rictal bristles and a distinctive juvenile plumage. They all exhibit sexual dimorphism in pluma ...

Blyth's Shrike-babbler
Blyth's 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 (other), white-browed shrike-babbler. Clements lumps this bird into the white-browed shrike-babbler. Description Blyth's 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 n ...
