Red-crowned Crane

The red-crowned crane is a large Northeast Asian crane and among the rarest cranes in the world. Adults are named for a patch of bare red skin on the crown, which becomes brighter in the mating season. Overall they are snow white, with black on the wing secondaries that can look almost like a black tail when the bird is standing, though the real tail feathers are white. Males are black on the cheeks, throat and neck, while females are pearly grey in these places. The bill is olive green to greenish horn, the legs slate to greyish black and the iris dark brown.

Juveniles are a combination of white, partly tawny, cinnamon brown, and rusty or greyish. The species is also called the Japanese crane or the Manchurian crane. In some parts of its range it is known as a symbol of luck, longevity and fidelity. (Wikipedia, general species account)
