Population justification: The population is estimated to number 2,500-9,999 mature individuals based on an assessment of recent records and surveys by BirdLife International (2001). This is equivalent to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: A moderate and on-going population decline is suspected to be occurring as a result of habitat loss and degradation in the wintering grounds, although up-to-date information on population trend is lacking.
