Population justification: In 2006, population size was estimated at 800 individuals based on two consecutive years of auditive censuses. A census at the end of 2010, which visited 93% of the known water springs, represents the most comprehensive survey of the species ever, and resulted in an estimate of 779 individuals (Aquasis in litt. 2011). It is placed in the band 250-999 individuals to account for uncertainty; this equates to 167-666 mature individuals, rounded here to 150-700 mature individuals. Following detailed survey work, Aquasis (2014) estimates that there are as many as 279 adult males in the population.

Trend justification: The species is assumed to be declining as forested habitat within its range is lost and the moist forest at springs that the species favours is being cleared to grow crops. Habitat quality is deteriorating due to deforestation, degradation of water resources and forest fires. In 2015, a fire destroyed 30ha of moist forest habitat, where suitable nesting habitat was found (W.A.G. Silva in litt. 2016).
