Distribution
This species is found in the northern parts of Europe and Asia. The Common Crane is an uncommon breeder in southern Europe, smaller numbers breeding in Greece, Yugoslavia, Romania, Denmark and Germany. Larger breeding populations can found in Scandinavia, especially Finland and Sweden. The heart of the breeding population for the species is in Russia, however, where possibly up to 100,000 cranes of this species can be found seasonally. In Russia, it is distributed as a breeder from the Ukraine region to the Chukchi Peninsula. The breeding population extends as far south as Manchuria but almost the entire Asian breeding population is restricted to Russia.
The species is a long distance migrant predominantly wintering in northern Africa. Fall migration is from August to October and spring migration is in March through May. Important staging areas occur anywhere from Sweden and Germany to China (with a large one around the Caspian Sea) and many thousand cranes can be seen in one day in the fall. Some birds winter in southern Europe, including Portugal, Spain and France. Most eastern Common Cranes winter in the river valleys of Sudan, Ethiopia, Tunisia and Eritrea with smaller numbers in Turkey, northern Israel, Iraq and parts of Iran. The third major wintering region is in the northern half of Indian subcontinent, including Pakistan. Minimal wintering also occurs in Burma, Vietnam and Thailand. Lastly, they winter in eastern China, where they are often the most common crane (outnumbering Black-necked Cranes ten-to-one). Migrating flocks fly in a V formation.
It is a rare visitor to Japan and Korea, mostly blown over from the Chinese wintering population, and is a rare vagrant to western North America, where birds are occasionally seen with flocks of migrating Sandhill Cranes.

Famous quotes containing the word distribution:
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.”
—Cyril Connolly (1903–1974)
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
