Justification of Red List category

Although the trend of western North American and Russian populations are unknown, the compilation of available data collected from 1977 to 2016 representing 75-80% of the global population, points to a decline of ≥30% over three generations. It has therefore been uplisted to Vulnerable. The cause(s) of declines are unknown, but are likely multi-faceted and further research is needed to inform conservation actions.
