Population justification: It is thought to be locally common in ideal habitat, but very patchy and absent from most forest, so the total population is likely to be very small.
During surveys in 2002-2005 and in February 2012, the following numbers have been reported: At Wabu Forest Reserve, 12 territories were recorded in 2003 (Dutson and Masibalavu 2004), and 16 in 2012); At Sovi Basin, three pairs were reported at Wainasa Creek in 2005, and 20 territories in 2012; At Monasavu, two sites each comprising c.2 pairs were recorded in 2002-2005, and 25 territories in 2012; At Namosi, two territories were recorded in 2012; At Mt Korobaba, it was heard on three occasions in 2003, and one territory was recorded in 2012; and at Tomaniivi, there were no records in 2002-2005, and two territories were recorded in 2012 (Dutson and Masibalavu 2004; Masibalavu and Dutson 2006; G. Dutson and V. Masibalavu in litt. 2006; V. Masibalavu in litt. 2007, 2012). Territories have been reported to comprise anything from several pairs with juveniles to lone pairs or a singing bird (Dutson and Masibalavu 2004, G. Dutson and V. Masibalavu in litt. 2006).
Based on extrapolations from density estimates produced by fieldwork, the population size is estimated to number 50-249 mature individuals (BirdLife International 2006), although it could potentially be greater than this.
Trend justification: Although the species is known from only very few sites, almost all are on steep terrain unsuitable for logging or cultivation, and no specific threats have been identified, so the population is suspected to be stable. Over ten years from 2009 - 2019, approximately 1.6% of forest with at least 50% canopy cover was lost within the species's range (Global Forest Watch 2020).
