Taxonomic note
Until recently considered conspecific with P. insularis, but differs in its smaller size (mean male tail, n=5, 55 mm vs 60.55, n=18, in insularis (Kirwan 2008); at least 1); (in male) paler, shorter throat patch (2); whitish vs smudgily grey-black upper breast below throat patch (2); bold white wingstripe (white tips of median coverts) (2); narrower black eyeline (ns1); paler grey crown and upperparts with weaker black streaking (ns1); almost pure white vs pale grey underparts (ns1); and (in female) no trace of grey throat patch of female insularis (ns1). Monotypic.

Population justification: The population has been estimated at fewer than 1,000 individuals (Ryan et al. 2009). The number of pairs is estimated to be c. 400, equivalent to c. 800 mature individuals (R. Porter in litt. 2016). To account for uncertainty, the population is placed here in the band of 250-999 mature individuals.

Trend justification: The population was previously suspected to be stable in the absence of any identified threats (R. Porter in litt. 2010). However, new information suggests that it may be experiencing declines after cyclones, and it is also subject to hunting for food which appears to be increasing (A. Saeed Suleiman in litt. 2020). Thus a decline is tentatively suspected (A. Saeed Suleiman in litt. 2016). Robustly establishing the current population size and current trend is a priority: evidence for a continuing decline would result in reassessment at a higher Red List category.
