# mallard vs mute swan

**mallard vs mute swan: mute swan leads on 3 of 3 measures**

Measured comparison — not a prediction

The most common wild duck in the Northern Hemisphere and the ancestor of nearly all domestic ducks. One of the heaviest flying birds, and the swan of European parks and rivers. On the measurements below, mute swan leads on more of them — but they do not all point the same way, and the ones that disagree are the interesting part.

## The measurements

|  | mallard | mute swan |
| --- | --- | --- |
| Mass | 0.7–1.6 kg | 7–15.5 kg |
| Length | 0.5–0.65 m | 1.25–1.7 m |
| Top speed | 88 km/h | — |
| Lifespan | 3–29 yr | 10–30 yr |

## Where each one leads

- Mass: mute swan is 10× heavier.
- Length: mute swan is 2.6× longer.
- Lifespan: mute swan is 2.4× a longer life.

## What this does and does not tell you

These are measured averages with real ranges behind them, and every figure links to its own page. What they cannot do is settle an encounter. Outcomes between animals turn on circumstance — who initiates, whether either is hungry, defending young, injured or cornered, and what the terrain favours. Size and bite force are not decisive on their own, and most of these pairs never meet in the wild in any case, because their ranges do not overlap.

> Every figure here is an average with a substantial spread. Individual animals vary enormously — a large individual of the smaller species routinely exceeds a small individual of the larger one.

## Common questions

### Is a mallard bigger than a mute swan?

mute swan is heavier — 7–15.5 kg against 0.7–1.6 kg.

### Who would win, a mallard or a mute swan?

That is not something measurements can settle. The comparison above shows which animal leads on each measure, but an actual encounter depends on circumstance, motivation, health and terrain — and most pairs like this never meet in the wild.
