Population justification: The global population size has not been quantified, but the species is described as generally uncommon to fairly common, although common in Borneo and extinct in Singapore (del Hoyo et al. 2007, Wells 2007, Eaton et al. 2021).

Trend justification: Despite the ability of this species to persist in degraded forest habitats, it is intolerant of oil palm plantations and there are indications that populations in fragmented secondary forest may be unable to persist long term. Remote-sensing data indicate rates of forest loss approximating 15% over three generations. Because of additional, unquantified fragmentation impacts, it is here tentatively suspected to be undergoing a decline of 15-25% in three generations (13.2 years).
