The IUCN Red List classifies this bird as an endangered species with population estimates of 250 to 999 mature individuals. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of legal and illegal logging, mining and conversion into farmlands through Slash-and-burn and urbanization.
