Crane
The common crane stands up to 120 centimetres tall and is one of the most recognisable migratory birds in the world. Its body is mostly grey, with a striking black and white head and a small patch of bare red skin on the crown. It breeds in wetlands, bogs and forest clearings across northern Europe and central Asia, building large nests close to water. Every autumn, millions of cranes take to the sky in one of the great wildlife spectacles of the season, following ancient flyways south to wintering grounds around the Mediterranean, the Middle East and East Africa. Pairs form bonds that last for life and perform elaborate dancing displays during courtship. The species is omnivorous, eating roots, seeds, berries, insects and small vertebrates depending on the season.
Habitat and distribution
Common cranes breed across a vast sweep of land stretching from Scandinavia and the British Isles east through Russia and into central Asia. They favour wetlands, shallow lakes, bogs and forest clearings where water is close at hand, using the surrounding vegetation as cover for their nests. After the breeding season, birds leave these northern grounds and travel south along established flyways to spend the winter around the Mediterranean basin, the Middle East and parts of East Africa. Spain is one of the most important wintering destinations in Europe, with the Extremadura region regularly hosting hundreds of thousands of birds. The species shows a clear preference for open farmland and river valleys during the winter months, where food is easier to find and flocks can keep watch for predators.
Diet
Few birds are as adaptable in their eating habits as the common crane. Across the year its diet shifts considerably depending on what is available. During the breeding season in northern wetlands, cranes take insects, worms, amphibians, small rodents and the occasional lizard or frog. Plant material is just as important: roots, tubers, berries and the seeds of grasses and sedges all feature regularly. On migration and during winter, the birds move onto farmland and feed heavily on leftover grain in harvested fields, particularly maize, wheat and acorns where oaks are nearby. This ability to switch between animal and plant foods means cranes can maintain their energy reserves through long journeys and harsh winters without relying on any single food source.
Behavior
Outside the breeding season, common cranes are among the most sociable of all large birds. Flocks of tens of thousands gather at key staging sites, and the noise of their bugling calls carries over great distances. Pairs bond for life and reinforce that bond each year through one of nature's most striking displays: the two birds face each other, bow, leap into the air, spread their wings and call loudly in what appears to be a kind of shared joy. This dancing behaviour also helps younger birds that have not yet found a mate to practise and signal their fitness. Within flocks, cranes maintain a clear social structure, with experienced adults often leading the group during flight and younger birds following in their wake.
Migration
Every autumn, common cranes leave their breeding grounds and set off on journeys that can cover several thousand kilometres. Two main flyways carry European birds southward: a western route through France and Spain toward wintering grounds in Iberia and Morocco, and an eastern route through the Balkans and Turkey toward the Middle East and East Africa. Cranes travel in large, noisy flocks, often flying in a V formation that helps birds conserve energy by riding the air currents created by those ahead of them. Stopover sites along these routes are critical, giving birds the chance to rest and refuel before pressing on. In spring the journey reverses, with birds returning north to breed, often arriving on or near the same wetlands they have used in previous years.
Conservation
The common crane is listed as Least Concern on the IUCN Red List, and its global population has recovered strongly after serious declines during the twentieth century, when hunting and the drainage of wetlands pushed numbers down sharply across Europe. Legal protection and the restoration of key wetland habitats have allowed populations to rebound, and the species has recolonised several countries where it had disappeared. Despite this good news, threats remain. The loss of wetlands to agriculture and urban development continues in parts of the range, and disturbance at stopover sites can force birds to burn precious energy reserves. Maintaining the network of protected areas along both the western and eastern flyways is essential to keeping the species secure well into the future.

Frequently Asked Questions
What do common cranes eat?
Common cranes eat a wide range of foods depending on the season. In summer they hunt insects, worms, frogs and small rodents, while also feeding on roots, berries and seeds. During winter on farmland they rely heavily on leftover grain, especially maize and wheat. This flexibility means they can fuel themselves through long migrations and cold winters without depending on any single food source.
How long do common cranes live?
Common cranes are long-lived birds. In the wild, individuals regularly reach 20 to 25 years of age, and birds in captivity have been recorded living beyond 40 years. Their survival over the long term is helped by the fact that they mate for life, meaning established pairs can raise chicks together year after year with growing experience and coordination.
Why do cranes dance?
The dancing of common cranes is one of nature's most memorable sights. Pairs bow, leap and spread their wings to strengthen the bond between them, repeating this display each breeding season. Younger birds that have not yet found a mate also dance as a way to practise and show off their fitness to potential partners. It is a behaviour rooted in communication rather than simple excitement.
Where do common cranes spend the winter?
After the breeding season, common cranes travel south to warmer regions. European populations mainly winter around the Mediterranean basin, with Spain receiving some of the largest concentrations on the continent. Extremadura, in western Spain, regularly hosts hundreds of thousands of birds. Other cranes head to the Middle East, Ethiopia and parts of East Africa, following flyways that their ancestors have used for thousands of years.
Are common cranes endangered?
Common cranes are currently listed as Least Concern by the IUCN, meaning the species is not considered at risk of extinction. In fact, populations have recovered well after steep declines in the twentieth century caused by hunting and the loss of wetlands. Legal protection and habitat restoration have made a real difference. That said, wetland loss and disturbance at key stopover sites remain ongoing concerns worth watching.
How far do common cranes migrate?
Common cranes are impressive travellers. Birds breeding in Scandinavia or northern Russia can cover several thousand kilometres on their way to wintering grounds in Spain, East Africa or the Middle East. They fly in large flocks, often forming a V shape that lets each bird benefit from the air currents created by the one ahead. Key stopover sites along the route give them a chance to rest and feed before continuing.
Do common cranes mate for life?
Yes, common cranes form pairs that typically last for their entire lives. Once a bond is established, the two birds return to breed together each year and reinforce their relationship through elaborate dancing displays. If one partner dies, the surviving bird will usually seek a new mate, but established pairs show a strong attachment to each other that biologists consider one of the most stable bonds found among birds.
