Taxonomic note
Glaucidium brodiei (del Hoyo & Collar 2014) previously included as subspecies sylvaticum and borneense, now split as Sunda Owlet (which see). Sometimes considered part of a species-group centred on G. passerinum (which see). Pale island form pardalotum distinctive. Proposed subspecies garoense (from W Meghalaya, in NE India) included in nominate. Name peritum is a synonym of sylvaticum. Two subspecies recognized.

Population justification: Described as common throughout its range (König and Weick 2008). No density estimates are available for this species (or any of its Asian congeners) and so a population size has not been estimated. Given the size of its vast range however, it is not considered likely to approach the thresholds (<10,000 mature individuals) for listing as threatened.
Trend justification: Forest loss in this species's range has been equal to c.8% over the last 10 years (Global Forest Watch 2021), and this rate is expected to continue. However, this species is very tolerant of degradation and occurs even in cultivated areas (albeit perhaps at lower densities [König and Weick 2008]) and so while the species is suspected to be declining, it is probably doing so at a slow rate.
