Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size (such estimates span 10-90 individuals per km2) and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: A moderately rapid population decline is suspected to be occurring, owing to habitat loss and degradation in both its breeding and non-breeding ranges. The requirement for mature primary forest within the South-East Asian wintering grounds suggests that this species may have been particularly vulnerable to recent habitat loss.
