Population justification: The global population is estimated to number c.16,000-84,000 individuals (Morrison et al. 2006).
Trend justification: A moderate and on-going decline is suspected based on surveys at staging posts. This is thought to be driven by habitat loss and conversion, but contaminants may also have an impact.
