Taxonomic note
The subspecies neilgherriensis has been moved from Z. aurea into Z. dauma, following song analysis that showed it to belong with the latter species (Weir 2018).
Previously, Zoothera dauma (Sibley and Monroe [1990, 1993]) and Z. imbricata (Collar [2004]) were lumped together into Z. dauma and subsequently split into Z. dauma, Z. major and Z. aurea following del Hoyo and Collar (2016).

Population justification: The global population size has not been quantified. The species is variously described as uncommon to fairly common across much of its range (Clement and Hathway 2000).
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and degradation.
