Justification of Red List category
This poorly known warbler has been uplisted from Vulnerable on the basis of the declining frequency of already very scarce records, suggesting that its population is smaller than previously thought.  It qualifies as Endangered because it is thought to have a very small population, which is in decline owing to habitat loss and degradation in its wintering grounds, and possibly in its breeding range.  Its breeding grounds are in urgent need of discovery.

Population size: 250-999

Population trend: Decreasing

Country endemic: No
