Population justification: There are estimated to be c.150,000 mature individuals (Rich et al. 2004).

Trend justification: The Partners In Flight Technical Committee has estimated this species's global trend as a more than 50% decline over c.40 years, a rate that would equate to a decline of c.20% or more per decade.
