Justification of Red List category
There are very few recent confirmed records of this species and sightings have become more and more infrequent, presumably as a result of declines caused by habitat loss and exploitation. No regular breeding, passage or wintering population is known, and the number of remaining individuals must be tiny. For these reasons the species qualifies as Critically Endangered.
