Adults are mostly snow-white with a black neck, cheeks, and throat. They have a striking patch of bare red skin on the crown, which becomes brighter during the breeding season. Secondary and tertiary wing plumes are elongated and black, drooping over the tail like a bustle when at rest. Juveniles have brownish plumage with mottled buff and white, lacking the red crown patch.

Conservation status
Endangered, with a decreasing trend primarily due to wetland destruction, agriculture expansion, and human encroachment.
Observation tips
Best observed in wetlands, marshes, and agricultural fields in eastern Hokkaido (Japan) or specific nature reserves in China and Korea during winter. Use spotting scopes to avoid disturbing them.
Interesting facts
