Red-crowned crane

The red-crowned crane (Grus japonensis) is a large gruid standing 150–158 cm tall, with a body length of 101–150 cm, a 220–250 cm wingspan and a weight of 4.8–10.5 kg. Its white plumage contrasts with black secondaries and tertials and a bare red crown. It breeds in the Russian Far East, north-eastern China and eastern Mongolia and winters on the Korean peninsula and in Chinese coastal wetlands, with a resident Hokkaido population. Reed marshes supply small fish, frogs, crabs and plant matter. The IUCN lists it Vulnerable, about 3,800 birds counted in winter 2020.
