Justification of Red List category
This species has a small, regionally declining population as a result of displacement following habitat conversion in its breeding grounds, mortality caused by lead poisoning in inland Japan, reduced breeding rate in the Magadan District caused by climate change, and reduced breeding success predominantly due to predation of nestlings by brown bears on Sakhalin Island. It is suspected that it will decline at a rate of 20-30% over three generations in the future as significant threats are ongoing, and some (such as climate change) are predicted to worsen. It therefore qualifies as Vulnerable.
