The common crane (Grus grus), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes. It is a medium-sized species, and classified as of least concern. It is the only crane commonly found in Europe apart from the demoiselle crane.
Habitat[change | change source]
In Europe, the common crane breeds in boreal and taiga forest and mixed forests, from sea-level to 2,200 m (7,200 ft). It also lives on treeless moors, on bogs, or on dwarf heather habitats, usually where small lakes or pools are also found.
In Sweden, breeders are usually found in small, swampy openings amongst pine forests while, in Germany, marshy wetlands are used. Breeding habitats in Russia are similar, though they can even be found nesting in the steppe and in semi-desert, so long as water is near. Mostly, common cranes are found breeding in wooded swamps, bogs and wetlands. They seem to need quiet, peaceful enivrons with little human interference. They live in low density, from 1 to 5 pairs per 100 km2 (39 sq mi).
During winter, the birds move to flooded areas, shallow sheltered bays, and swampy meadows. During the flightless moulting period there is a need for shallow waters or high reed cover for concealment. Later, after the migration period, the birds winter regularly in open country, often on cultivated lands and sometimes also in savanna-like areas, for example on the Iberian Peninsula.
