Justification of Red List category
This species was formerly recorded frequently on its non-breeding grounds but there has been a rapid attrition of sightings, with only a single probable record (in 2019) since 2015. It is therefore suspected to have declined extremely rapidly over the past ten years and is assessed as Critically Endangered. The loss and degradation of habitat in its wintering grounds (and possibly too its unknown breeding grounds) is thought to be the principal cause of its decline. Its breeding grounds are in urgent need of discovery as is the protection of any remaining marshlands that may contain suitable habitat for the species in the Philippines.
