Taxonomy
The mute swan was first formally described by the German naturalist
Johann Friedrich Gmelin as ''Anas olor'' in 1789, and was transferred by
Johann Matthäus Bechstein to the new genus ''Cygnus'' in 1803. Both ''cygnus'' and ''olor'' mean "swan" in

Young birds, called cygnets, are not the bright white of mature adults, and their bill is dull greyish-black, not orange, for the first year. The down may range from pure white to grey to buff, with grey/buff the most common. The white cygnets have a leucistic

gene. Cygnets grow quickly, reaching a size close to their adult size in approximately three months after hatching. Cygnets typically retain their grey feathers until they are at least one year old, with the down on their wings having been replaced by flight feathers earlier that year.
All mute swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water.

Behaviour
Mute swans nest on large mounds that they build with waterside vegetation in shallow water on islands in the middle or at the very edge of a lake. They are monogamous and often reuse the same nest each year, restoring or rebuilding it as needed. Male and female swans share the care of the nest, and once the cygnets are fledged it is not uncommon to see whole families looking for food. They feed on a wide range of vegetation, both submerged aquatic plants which they reach with their long necks, and by grazing on land. The food commonly includes agricultural crop plants such as oilseed rape and wheat

The mute swan is less vocal than the noisy whooper and Bewick's swans; they do, however, make a variety of sounds, often described as "grunting, hoarse whistling, and snorting noises." During a courtship display, mute swans utter a rhythmic song. The song help synchronize the movements of their heads and necks. It could technically be employed to distinguish a bonded couple from two dating swans, as the rhythm of the song typically fails to match the pace of the head movements in two dating swans. Mute swans usually hiss at competitors or intruders trying to enter their territory. The most familiar sound associated with mute swans is the vibrant throbbing of the wings in flight which is unique to the species, and can be heard from a range of , indicating its value as a contact sound between birds in flight.[ Cygnets are especially vocal, and communicate through a variety of whistling and chirping sounds when content, as well as a harsh squawking noise when distressed or lost.
]
Mute swans can be very aggressive in defence of their nests and are highly protective of their mate and offspring. Most defensive acts from a mute swan begin with a loud hiss and, if this is not sufficient to drive off the predator or intruder, are followed by a physical attack. Swans attack by striking at the threat with bony spurs in their wings, accompanied by biting with their large bill, while smaller waterbirds such as ducks are normally grabbed with the swan's bill and dragged or thrown clear of the swan and its offspring. The wings of the swan are very powerful, though not strong enough to break an adult man's leg, as is commonly misquoted. Large waterfowl, such as Canada geese

, (more likely out of competition than in response to potential predation) may be aggressively driven off, and mute swans regularly attack people who enter their territory.[
The cob is responsible for defending the cygnets while on the water, and will sometimes attack small watercraft, such as canoes, that it feels are a threat to its young. The cob will additionally try to chase the predator out of his family territory, and will keep animals such as foxes and raptors at bay. In New York (outside its native range), the most common predators of cygnets are common snapping turtles.] Healthy adults are rarely preyed upon, though canid

s. In England, there has been an increased rate of attacks on swans by out-of-control dogs, especially in parks where the birds are less territorial. This is considered criminal in British law, and the birds are placed under the highest protection due to their association with the monarch. Mute swans will readily attack dogs to protect themselves and their cygnets from an attack, and an adult swan is capable of overwhelming and drowning even large dog breeds.
The familiar pose with neck curved back and wings half raised, known as busking, is a threat display. Both feet are paddled in unison during this display, resulting in more jerky movement. The swans may also use the busking posture for wind-assisted transportation over several hundred meters, so-called windsurfing.
Like other swans, mute swans are known for their ability to grieve for a lost or dead mate or cygnet. Swans will go through a mourning process, and in the case of the loss of their mate, may either stay where its counterpart lived, or fly off to join a flock. Should one of the pair die while there are cygnets present, the remaining parent will take up their partner's duties in raising the clutch.
Breeding
Mute swans lay from 4 to 10 eggs. The female broods for around 36 days, with cygnets normally hatching between the months of May and July. The young swans do not achieve the ability to fly before about 120 to 150 days old. This limits the distribution of the species at the northern edge of its range as the cygnets need to learn to fly before the ponds and lakes freeze over.

For many centuries, mute swans in Great Britain were domesticated for food, with individuals being marked by nicks on their webs (feet) or beaks to indicate ownership. These marks were registered with the Crown and a Royal Swanherd was appointed. Any birds not so marked became Crown property, hence the swan becoming known as the "Royal Bird".
