Population justification: Surveys in 2014 estimated 144 individuals (SOP Manu 2015), roughly equivalent to 96 mature individuals, rounded here to 100 mature individuals.
Trend justification: Approximately the same number of birds were detected annually in surveys from 2006-2008 (Gouni et al. 2006, Gouni and Zysman 2007, D. Kesler in litt. 2008, 2009, 2010), with slight increases in 2009 and 2014 (Gouni et al. 2009, SOP Manu 2015), 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.
