Population justification: The global population size has not been quantified, but the species is described as abundant in the central provinces of Sri Lanka, particularly above elevations of 850 m (del Hoyo et al. 2005; E. Goodale in litt. 2020).

Trend justification: Forest loss has been low within the species's range in recent years, equating to population declines of <2% (Global Forest Watch 2020) over three generations (10.9 years). The species is also able to persist and indeed may be abundant within degraded agricultural areas (Goodale et al. 2014; E. Goodale in litt. 2020). In the absence of substantial evidence of a decline and low immediate risk (Fishpool and Tobias 2020) the species's population trend is suspected to be stable. Given the small range of the species continued monitoring of abundance and rates of habitat loss remains important in order to detect population changes.
