Common cranes (aka Eurasian cranes) often gravitate to wet open fields, bogs, and marshes. This flock is congregating in the Drömling wetland in Germany. The most widely distributed of all the 15 species of cranes, its native range covers a wide swath of Europe and Asia, with the largest breeding populations in Russia and Scandinavia. As winter approaches, common cranes make the long journey south, often in large flocks of about 400 birds, to North Africa or parts of southern Europe and Asia in search of more civilized temperatures.
