Population justification: Surveys in 2009 estimated 135 individuals, roughly equivalent to 90 mature individuals.

Trend justification: Approximately the same number of birds were detected annually in surveys from 2006-2008 (with a slight increase in 2009), and data from radio-marked and colour-banded birds do not indicate a major population crash or major population increase (D. Kesler in litt. 2009, 2010). However, studies of demography (Kesler et al. 2012a) indicate that the population may be declining substantially, and that juvenile survival and adult female survival may be the life history stages most compromised in the population.
