Population & trend

  Estimate Data quality Derivation Year of estimate
No. of mature individuals 2500-9999 medium Estimated 2000
Population trend Decreasing poor -
Number of subpopulations 2-100 - - -
Largest subpopulation 251-999 - - -
Generation length (yrs) 9 - - -
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, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: There are no quantitative data available to calculate population trends; however, the species is suspected to be declining slowly, owing to pressure from hunting for its plumes.
