Physical description Click here for a physical description Mute Swans are large birds with an all-white plumage. Although heavy, once airborne they are good fliers. They have long necks and short, sturdy legs. From the base of the bill to the eyes they have a black triangular patch. Ontop of the bill there is a "knob". Male Mute Swans have a bigger knob than females. The irises are dark; the bill is pink, with a black tip. The legs and the fully webbed feet are dark-grey to black. Cygnets and juveniles have homogeneously grey feathers until they moult into adult plumage.

Taxonomy, classification See Mute Swan at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Mute Swan is available HERE . Mute Swans occur naturally only in temperate Europe and western Asia. Depending on seasonal conditions, they are partly migratory, especially in the northern parts of their range. Significant populations have been introduced into other parts of the world, in particular large parts of North America (mostly the north-eastern United States and the West coast), New Zealand and Japan. In Europe, Mute Swans are found in the central and eastern to south-eastern parts of the continent, on the British Isles, in southern Scandinavia and along parts of the Mediterranean and Black Sea coastlines. Mute Swans have a strong preference for fresh water aquatic habitats, such as rivers and lakes.

Sightings Click here for sighting information We have seen Mute Swans in parts of the southern Eifel and Rheinhessen in 2006, 2010 and 2014. C. Pears reports finding Mute Swans in various locations in England in January 2011 and in February 2013. D. Wilczynska reports spotting Mute Swans at Lake Ros, Masurias, Poland, in August 2014, and in Biebrza NP, Poland, in May 2017. Several contributors report spotting Mute Swans in various parts of Germany, e.g. on the river Rhine and the river Moselle, and on Fehmarn island. In parklands along the river Rhine several pairs were found nesting in April 2017. The species was also found at Lake Constance, Germany. J. Pires reports that there are wild Mute Swans on the rivers around Mora, Evora, Portugal. M. Eaton reports spotting wild Mute Swans at Mequinenza, Zaragoza, Aragon, Spain, in September 2019. M. Eaton also found Mute Swans in St. James's Park, London, England, in September 2019. In the past we used to see Mute Swans regularly in various parts of Germany, on lakes and rivers, but also in urban parks.

Behaviour

Mute Swans can become surprisingly tame. C. Pears related the story of a wild pair of Mute Swans deciding to nest in someone's back garden in Devon, England, and one of their offspring then staying on with its partner, raising a brood every year over a period of more than 20 years.
