Population justification: The population is placed in the band 50-249 mature individuals, equating to 75-374 individuals in total, rounded here to 70-400 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 ten years, 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.
