When this species was uplisted from Least Concern to Vulnerable in the 2009 Red List update, there was some evidence to suggest that declines may have exceeded a rate of 50% during the past three generations or 45 years (Beilfuss et al. 2007), but data were regarded as patchy and an overall decline of 30-49% was considered a more reasonable estimate. Overall estimates suggest that the species’s global population has declined from over 100,000 individuals in 1985 to 50,000-64,000 individuals in 2004 (Beilfuss et al. 2007). This implies that the species may have declined by over 50% in 19 years, and when these data are extrapolated to a period of 45 years in the past (1967-2012) or past and future (1985-2030), assuming an exponential trend, the calculated rate of decline is c.65-80%.
