Population justification: The global population size has not been quantified, but the species is now local and uncommon in many areas where it was formerly common and widespread (Kennedy et al. 2000).

Trend justification: It appears to have undergone a rapid decline on Luzon, where it was common throughout the island including areas around Metro Manila in the early 1990s, but has since has disappeared from most of these areas and has virtually disappeared from Candaba Marsh where it was easily seen until just a few years ago (R. Hutchinson and I. Sarenas in litt. 2013). It persists in some areas and on some smaller islands but overall a rapid population decline is suspected to be taking place over three generations (16 years).
