Population justification: The global population size has not been quantified, but the species was previously described as generally common and one of the most frequently encountered birds on Gunung Kerinci (Eaton et al. 2015). None have been reported from this site since 2008, and there are very few records of the southern and central Sumatran subspecies laurinae since then throughout the range. The subspecies rookmakeri is still present in reasonable numbers in monatane forest in Aceh, but is infrequently seen and present in areas with significant trapping activity.

Trend justification: The population is suspected to be in decline due to extremely high levels of trapping to supply the domestic cage bird trade in Indonesia.
