Population justification: The species has been recorded across a large area, but the paucity of recent sightings suggests that the population size may now be very small. The population is therefore placed in the band 50-249 mature individuals. Dedicated surveys and quantified population estimates would be desirable to confirm this.
Trend justification: The population is suspected to be declining at a rate of 1-19% over three generations, in line with habitat loss within its highly fragmented range. Given the patchy nature, spatially and temporally, of bamboo stands, and the known impact that habitat fragmentation has had on other semi-colonial columbiformes historically, it may have declined or be continuing to decline at a much more rapid rate, with serious conservation implications.
