Justification of Red List category
This species has an extremely large range in both the breeding season and in winter, and an extremely large population. The population was not thought to be declining sufficiently rapidly to approach the threshold for Vulnerable under the population size reduction criterion. However new information suggests the population has declined rapidly across the majority of the range, and it has therefore been uplisted to Vulnerable. Although the species might be expected to benefit from a reduction in eutrophication, this does not appear to have been the case.
