Population justification: In 2007 the population was estimated at 250-300 individuals including 70 birds discovered at a dry season roost site (Waugh 2007). Given the uncertainty over the number of mature individuals this is placed in the band 50-249 until better data are available.
Trend justification: The population is currently thought to be stable (I. Berkunsky in litt. 2012) following successful conservation measures and near elimination of trade, which caused extremely rapid declines during the 1970s and 1980s. However, given its longevity the trend over the past three generations has still been negative and declines of over 80% during the period are suspected. Growth rate estimates generated by a Population Viability Analysis did not reach the rate of replacement needed for the population to remain viable in the long-term (Strem and Bouzat 2012).
