It is a medium-sized species, and classified as of least concern.<ref name=IUCN/> It is the only crane commonly found in Europe apart from the [[demoiselle crane]]. == Habitat == In Europe, the common crane breeds in [[Taiga|boreal and taiga]] [[forest]] and mixed forests, from [[sea-level]] to {{convert|2200|m|ft|abbr=on}}. It also lives on treeless [[moor]]s, on [[bog]]s, or on dwarf [[heather]] [[habitat]]s, usually where small [[lake]]s or [[pool]]s are also found. In [[Sweden]], breeders are usually found in small, [[swamp]]y openings amongst [[pine]] forests while, in Germany, [[marsh]]y [[wetland]]s 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 {{convert|100|km2|sqmi|abbr=on}}. During winter, the birds move to flooded areas, shallow sheltered bays, and swampy meadows. During the flightless [[moult]]ing period there is a need for shallow waters or high [[Reed (plant)|reed]] cover for
