Not globally threatened (Least Concern). Restricted-range species: confined to the Palawan EBA, an area of considerable biological importance subject to significant threat levels, mainly due to habitat destruction and degradation. Population believed to be stable and is generally common, but trade for cagebirds is a potentially a much greater threat than habitat modification and loss.
