Justification of Red List categoryVarious efforts to monitor the populations of this large long-distance migrant shorebird indicate that a significant decline is taking place, most severely noted in numbers recorded at migratory sites in North America but evident in count data assembled for key wintering areas. Rates of reduction could well exceed 30% over three generations and accordingly the species is assessed as Vulnerable. At present the drivers of such declines are uncertain, although the loss of and disturbance to key non-breeding and stopover sites is suspected to impact populations and climate change driven habitat shifts may be causing prey mismatches that affect reproductive output, as well as altering fine-scale habitat suitability.
