Population justification: BirdLife Fiji surveys found this species to be fairly common in native forests, with 36 birds recorded (mostly calling males) in 23.5 hours in a mixed lowland and montane site, and 13 birds in 15 hours at a montane site. Estimating an average pace of 1 km/hour and an effective detection distance of 25 m each side of the trail, this suggests that around 31 and 17 birds were detected per km2 at these sites. There are a number of likely errors in this estimate, which must be treated as very provisional.
The area of dense and medium-dense forest on Kadavu is around 225 km2, suggesting that the total population falls in the band 2,500-9,999 birds (unpublished data from Fiji IBA project via G. Dutson in litt. 2005). This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
The species also occurs on the island of Ono, which probably constitutes a separate subpopulation as fantails rarely cross the sea, totalling about 5% of the total population.
Trend justification:
The population is suspected to be declining owing to forest loss and degradation. For the ten years to 2021, remote sensing data indicate that c.2% of forest was lost in this species' range (Global Forest Watch 2022, using data from Hansen et al. [2013] and methods disclosed therein), although this is likely to accelerate slightly (to an equivalent rate of 2-4%) in the future based on losses in 2016-2021. Agricultural encroachment is considered the main cause of forest loss (Conservation International Pacific Islands Program 2013) and Kadavu has suffered extensive fires (unpublished data from Fiji IBA project via G. Dutson in litt. 2005) which are increasing in frequency (Boles 2020).
