(Grus japonensis)


The red crowned crane, also called the Japanese and Manchurian crane, belongs to the order Gruiformes. Other representatives of this order that can be seen at Woodland Park Zoo are the sunbittern and the gray-winged trumpeter. Cranes belong to the family Gruidae. Of the 15 species of cranes, red crowned cranes are most closely related to the whooping crane of North America.

Range and Habitat

There are two distinct populations of red crowned cranes. A resident population lives year-round on the island of Hokkaido, Japan.

The other population lives on the mainland where they breed in reed swamps and wet meadows in northern Manchuria and southeast Siberia. This population winters in paddy fields and grassy tidal flats in South Korea and eastern China.

Length and Weight

Adult length: 53 inches (136 cm)

Adult weight: 15-20 pounds (7-9 kg).

Life Span

Life span in the wild is unknown. There is one record of a red crowned crane living 25.5 years in captivity.


In the wild: In general, this species feeds on a variety of invertebrates and small vertebrates. During the non-breeding season in the fall in South Korea, this species feeds on earthworms, small crabs and aquatic invertebrates and some plant seeds. In the winter, they move to paddy fields where they feed on rice. During the winter, the Hokkaido population feeds on corn at artificial feeding stations.

At the zoo: Crane pellets, crickets, mealworms, earth worms, small fish and krill.


Male and female red-crowned cranes mature sexually at 3 to 4 years of age, but frequently will take longer to form pair bonds and successfully reproduce. As with all cranes, red-crowned cranes form lifelong monogamous pair bonds.

Egg-laying occurs in the early morning hours and two eggs are laid two to four days apart. The clutch is incubated for 29-31 days by both birds. The female does most of the incubating, with the male on the nest during the middle part of the day.

Life Cycle

Mainland red crowned cranes breed and nest in northern Manchuria and southeast Siberia. Breeding takes place in late March and April, with the first eggs arriving in late April. As winter approaches, the mainland population migrates to South Korea and China. Those migrating to South Korea arrive in mid-November to early December. They leave South Korea in March. Those birds that winter in China arrive in late October to mid-November, and leave China in March.

Beautiful Dancers

Red crowned cranes are renowned for their spectacular and elaborate courtship dances. During these graceful displays (usually performed in pairs), birds circle each other while leaping and calling, head-bobbing toward one another and bowing with spread wings. Grasses, sticks or feathers are frequently tossed in the air. These dances can be observed throughout the year as the birds continually reinforce their pair bonds.

Singing a Different Song

Unison calling between males and females serves three distinct functions: formation and maintenance of pair bonds; territorial advertisement; and competitive or combative signaling. Unison calling also helps distinguish males from females. The unison call is usually initiated by the female. For each male call that follows, females from the mainland population of red-crowned cranes respond with two notes. Hokkaido red crowned crane females answer with three to four call notes.

Location at the Zoo

The zoo's red crowned cranes can be seen adjacent to the Temperate Wetlands exhibit in the Temperate Forest. Other Asian cranes in the vicinity are the white-naped cranes and hooded cranes.

Conservation Connection

Seven of the 15 species of cranes are listed as threatened or endangered. The red crowned crane is listed at endangered. The destruction of natural habitat on breeding grounds, in wintering areas and along migration routes is having a devastating effect on crane and other migratory bird populations. Specific threats for the red crowned crane are drainage of wetlands and reclamation of wintering grounds for agriculture. In 1996, the wild population estimates for the red crowned crane in North and South Korea and Japan was 1,700-2,000 birds.

With several other zoos, Woodland Park Zoo is participating in the Association of Zoos & Aquariums' (AZA) Species Survival Plan (SSP) for red crowned cranes. SSPs include conservation-oriented research, breeding of selected animals to maintain genetic diversity and cooperative educational efforts. As an example, fertile red crowned crane eggs have been sent by other zoos to the Khinganski Nature Reserve in Russia. Reserve staff have been trained by SSP staff to raise these cranes in captivity and eventually release them back into the wild.

The pair of birds on exhibit at Woodland Park Zoo were received in 1992 from Kobe Zoo, Japan. These birds are on our high priority list to breed. This pair have successfully reproduced the last two years and have added to the genetic diversity of the captive population.

How You Can Help!

The effort to save endangered species requires cooperation and support at the international, national, regional and individual levels. You can help in this cause. Join and become active in Woodland Park Zoo and other conservation organizations of your choice. Recycle forest products. Eliminate or reduce pesticide use.

Contact Woodland Park Zoo at to find ways you can support conservation programs at the zoo.

Red Crowned Crane Fascinating Facts

  • The red-crowned crane is an important symbol to the people of Japan and other Asian countries. It typically represents long life, peace, happiness and fidelity!
  • The Demilitarized Zone between North and South Korea has become a winter sanctuary for red-crowned and white-naped cranes. This restricted area allows little human activity!
  • In 1929, there were fewer than 20 birds in Hokkaido, Japan. In the 1950s, artificial feeding in winter began. Today, there are about 450 birds in this population.
