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, suggesting that the species' population is more or less stable (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.
Trend justification: The species is assumed to be declining as an area known to hold seven active nests was burnt in 2004-2005 and the moist forest at springs that the species favours is being cleared to grow crops.
