This is the nominate race from the Western Himalayan foothills characterized by more rufous color including contrasting tawny cheek patch and rufous shaft streaks seen here. Four or five subspecies usually recognized. Formerly included in the genus Garrulax, Clements, IOC and H&M place it in Trochalopteron, a clade of babblers that are phylogenetically separate from Garrulax (Gelang et al. 2009). However HBW includes this species in the genus Strophocincla (Wolters 1980) usually listed as a genus of doubtful validity (See GBIF). Laughingthrushes were formerly included in the Timaliidae (Babblers) but Fregin et. al (2012) split the Babblers into five families in which the Laughingthrushes are in their own family, the Leiothrichidae. This is the taxonomy followed by Clements, IOC and H&M. However, a recent paper by Moyle et al. (2012) splits the Babblers into only three families. Under this scheme the Laughingthrushes become a subfamily (Leiothrichinae) of the Timaliidae rather than a separate family. Canon PowerShot SX50 HS.
