Taxonomic note
A comprehensive phylogenetic analysis of bulbuls (Shakya and Sheldon 2017) has indicated that Striated Bulbul is sister to a large clade of several robust genera and is moved to its own genus, Alcurus Blyth, 1842. Therefore it becomes Alcurus striatus (Handbook of the Birds of the World and BirdLife International 2019).

Population justification: The global population size has not been quantified, but the species is described as generally fairly common throughout its range (del Hoyo et al. 2005). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
