Population justification: The global population size has not been quantified, but the species is described as moderately common in the interior of forests (del Hoyo et al. 2006).

Trend justification: The population is suspected to be in decline due to loss and degradation of its habitat, but the trend has not been directly estimated. Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 40 km2. This roughly equates to a rate of forest loss of 2.7% over three generations (14.7 years) for this species. The only threat known to the species is forest clearance. Long-tailed Fantail occurs in primary and secondary forest; thus, it may not be severely affected by deforestation and the rate of decline may be slower than the rate of forest loss.
