Population justification: This species is described as rare throughout its restricted range, with very few recent observations (Dutson 2011, Callaghan et al. 2019). It must have been locally common when the Whitney expedition collected a total of 37 specimens from each of the three mountains visited in 1930 (Mayr 1931). Subsequently, few ornithologists have visited these mountains, but the species appears to be very localised and rare. In 1990, one individual was seen at 750 m on the slopes of Mt Ire (P. Scofield in litt. 1992, 1994), in 1994, a single bird was seen at 1,100 m above Arullange village (Gibbs 1996), and in 1997, a pair was seen at 1,160 m above Arullange (G. Dutson pers. obs. 1997). None were seen in 1997 on the 940 m summit of Mt Alsa'an (G. Dutson pers. obs. 1997). Two individuals were observed during surveys of East Kwaio in 2018 (Callaghan et al. 2019). Overall there have been very few recent observations, although the species is described as being well-known to the local community and is thought to occur at at least three geographic localities (Callaghan et al. 2019). The total population is suspected to number fewer than 1,000 mature individuals, placed in the band 250-999 (G. Dutson in litt. 2000), equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: There are no data on population trends, although the species appears to be recorded less frequently than in the past (Dutson 2011, Callaghan et al. 2019). It remains uncertain whether this species has declined or whether it remains locally common on mountains unvisited in recent years.
