Mute Swan Bird Facts (Cygnus olor)

Visual Identification

Appearance

The Mute Swan is a majestic waterbird with pure white plumage, a long S-shaped neck, and a distinctive orange bill with a black base and knob. Their legs are black with webbed feet.

Males (cobs) are generally larger than females (pens) and have a more prominent black knob at the base of the bill. Juveniles display greyish-brown feathers, gradually turning white over their first year.

Distribution

Mute Swans inhabit a variety of freshwater habitats, including lakes, ponds, slow-moving rivers, and coastal lagoons. They are native to much of Europe and parts of Asia, and have been introduced to North America, Australia, and New Zealand.

They prefer water of 0.2 - 0.45 meters (8 to 18 inches) deep, where they can easily reach the bottom with their bill.

In the UK, they are widespread residents, while in North America, they are found primarily in the Northeast, Great Lakes region, and Pacific Northwest. Their distribution can vary seasonally, with some populations undertaking short-distance migrations.

Distribution Map

This map gives you a rough idea of where you might spot a Mute Swan. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
Where birds live can change with seasons and available food
This map is quite simple - it doesn't show exact locations

We're working on making our maps even better! Soon, we hope to show you:

Bird Attributes Explained

Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.

Attribute Categories:

Agility: Manoeuvrability, speed, and grace in flight or movement.
Strength: Physical power, often correlating with size and hunting abilities.
Adaptability: Ability to thrive in various environments or changing conditions.
Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
Endurance: Stamina, often seen in migration patterns or foraging behaviours.

Understanding the Ratings:

0-20: Very Low
21-40: Low
41-60: Average
61-80: High
81-100: Very High

Remember, these attributes are relative to other bird species and don't necessarily indicate superiority.

Agility 75

Agility

Reflects the bird's manoeuvrability, speed, and grace in flight or movement.

Mute Swans display considerable agility in water, gracefully manoeuvring with their long necks and powerful webbed feet. Their ability to take off from water and perform precise landings demonstrates good aerial agility for their size, though they're less nimble on land.

Strength 85

Strength

Indicates the bird's physical power, often correlating with size and hunting abilities.

As one of the heaviest flying birds, weighing up to 14 kg, Mute Swans possess remarkable strength. Their powerful wings enable them to take flight and maintain sustained periods aloft, whilst their strong necks and bills are formidable in territorial disputes.

Adaptability 70

Adaptability

Represents the bird's ability to thrive in various environments or changing conditions.

Mute Swans show good adaptability, thriving in various freshwater habitats from natural lakes to urban ponds. They've successfully established populations outside their native range, adapting to new environments. However, they're somewhat specialist in their aquatic lifestyle and diet.

Aggressiveness 80

Aggressiveness

Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.

During breeding season, Mute Swans are notably aggressive, fiercely defending their nests and young. They're known to confront and chase off potential threats, including much larger animals and humans. This protective behaviour contributes to their successful breeding in various environments.

Endurance 90

Endurance

Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.

Mute Swans demonstrate exceptional endurance. Their ability to undertake long-distance flights during migration, combined with their long lifespan of up to 30 years in the wild, showcases remarkable stamina. Their large size and efficient swimming also contribute to their high endurance in aquatic environments.

Diet

Mute Swans are primarily herbivorous, feeding on aquatic vegetation, which they reach by upending in shallow water.

They also consume small aquatic animals (mainly frogs, tadpoles and insects) and occasionally graze on land, sometimes grain in farmland when the water freezes.

In urban areas, they may supplement their diet with bread offered by humans, though this is not recommended. They also eat small dead or dying fish, although they struggle to swallow larger meals.

Behaviour

Mute Swans are known for their graceful swimming, often with wings slightly raised in a display called 'busking'. They are territorial during the breeding season, aggressively defending their nests and young.

These swans form long-term pair bonds, often engaging in synchronised swimming and head-bobbing courtship rituals.

Vocalisation

Despite their name, Mute Swans are not silent. They produce a variety of soft grunts, hisses, and snorts, particularly when threatened or during courtship.

Their most notable sound is the rhythmic throbbing hum made by their wings during flight, often described as a 'singing' sound.

Nesting & Breeding

Mute Swans typically breed from age 3 to 4, forming monogamous pairs that often last for life. The breeding season begins in spring, and courtship displays include synchronised swimming and mutual head-bobbing.

Nests are large mounds of vegetation built near water edges, often on small islands. Females lay 5-8 pale blue-green eggs, which fade to white over time.

Incubation lasts about 36 days, and the female primarily performs it while the male guards the nest. Cygnets fledge at 120-150 days but may stay with their parents through the next winter.

Conservation and Status

Global Conservation Status

Least Concern ^[1]

While Mute Swans are currently listed as Least Concern, they face threats from habitat loss, lead poisoning from ingested fishing weights, and collisions with power lines.

Conservation efforts focus on protecting wetland habitats and regulating lead use in fishing equipment.

Predators

Adult Mute Swans have few natural predators, but eggs and cygnets may fall prey to foxes, large birds of prey, and pike.

Did You Know?

Mute Swans can live up to 30 years in the wild, one of the longest lifespans among wild birds. There are anecdotal reports of captive Mute Swans living for 70 years in captivity.
They are one of the heaviest flying birds, with some males weighing up to 14 kg.
In the UK, all unmarked mute swans in open water are traditionally considered property of the Crown.

FAQs

Are Mute Swans still invasive?

Mute Swans are invasive in the United States, where they are non-native. They are considered harmful to natural environments and a nuisance for people in many areas, and their population continues to grow.

Can you keep a Mute Swan as a pet?

Mute Swans can be kept as pets on private American properties with substantial ponds. However, owning such a large bird is a serious long-term commitment, and all steps should be taken to stay within the lawn and prevent these birds from escaping into wild waterways.

Keeping Mute Swans is illegal in some states, so check in with authorities before purchasing these birds. You may not keep a pet swan in the United Kingdom.

How did the Mute Swan get to America?

Mute Swans were brought to America from Europe. These undeniably beautiful waterfowl were introduced to ponds in parks and estates as an ornamental attraction, an activity still practised today on private properties.

How do Mute Swans affect the environment?

Mute Swans are large birds with a serious appetite. They are part of the natural ecosystem in the United Kingdom and Europe, but these newcomers cause damage in the United States. There, they outcompete native waterfowl and alter small wetlands by overgrazing the aquatic vegetation and kicking up sediments in the water column.
