Physical description Click here for a physical description Common Cranes are tall, stately birds with extremely long legs and also a very long neck. Their breeding plumage is is almost all-grey. Only the upper part of the long neck and the head are black (frons, chin, front of the neck, nape of the neck) and white (sides of the head to the back of the neck), with a bare red skin patch of variable size at the back of the head. Their extremely long tertial flight feathers look bushy when the wings are folded, giving the impression of a massive tail. The vent and undertail are darker grey than the rest of the body. In eclipse the back turns brownish. The irises are yellow. The bill is grey to turquoise-green-grey; the legs and feet are grey. Juvenile birds have a brownish head and upper neck, with no black and white markings or red skin patch yet.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to the ebird.org website. The global distribution of the Common Crane is available HERE . Common Cranes are a strongly migratory bird species that flies long distances between winter quarters and breeding grounds. Some spend the winters in southern Spain and parts of the north-western African coastal fringe, others in East Africa and southern Arabia (near the Red Sea), in Iraq/Iran, the fringes of the Himalayas and parts of China. The Common Crane's breeding grounds range from eastern and northern Europe all across the Asian tundra to almost the Barent Sea. Common Cranes wintering in Spain/northern Africa migrate via a well-defined, narrow corridor over central Spain, the western edge of the Pyrenees, along the Bay of Biscaye, via central France and western to northern Germany to their breeding grounds in eastern Europe. Apart from some locations in Turkey, the Common Cranes' breeding grounds are located in Poland and Scandinavia (but not the western, near coastal fringe and mountain ranges), and further eastward.

Sightings Click here for sighting information Race "grus" D. Wilczynska reports spotting Common Cranes, race "grus", near Malkinia, Masovia, Poland, in March 2016 and at Jelonki near Ostrow Mazowiecka, Masovia, Poland, in August 2015 and in April 2016. They are also regularly seen in wetlands around the river Bug, near Brok, Masovia, Poland, where they can be found breeding in significant numbers. H. Dahlem-Senger reports spotting Common Cranes, race "grus", on their migration via the western European pathway from Poland to northern Africa via Iberia in November 2016, when they flew over Eltville, Hessen, Germany. In the 2018 breeding season the first flocks were heard crossing western Germany in late January to early February. A large flock was found flying over towards their winter quarters in early November 2020. Common Cranes, race "grus", were found by J. Pires at both Embalse de Los Canchales, near Montijo, Spain, and Monte do Espargueiro, Mourao, Evora, Portugal, in December 2019. These birds were overwintering in Iberia. In the past we have seen Common Cranes, nominate race "grus", migrating above Germany, in particular the Eifel, Rheinland-Pfalz, on their way from Spain to their breeding grounds over decades since the 1960ies.

Breeding information

Breeding season: Apr(?) - June(?)

Eggs: 2

Incubation period: ca. 30 days

Fledging age: ca. 63 days

Eggs are usually laid in May. Usually a clutch consists of 2 eggs, rarely 1 or 3 (or even 4) eggs are laid. The nest is usually close to, or surrounded by, water. Chicks are precocial, i.e. they leave their nest at a very young age, but they only start to fly short distances at ca. 9 weeks old. Until then they wander around with their parents, who at the time are also going through a moult and are flightless for 5-6 weeks.

Nest building: ?

Incubation: Female (& male)

Dependent care: Female & male

Nest

Type: Basket

Material: Reed stems, twigs, leaves
