# golden eagle vs mallard

**golden eagle vs mallard: golden eagle leads on 4 of 4 measures**

Measured comparison — not a prediction

One of the most widely distributed eagles, and a bird flown in falconry for two thousand years. The most common wild duck in the Northern Hemisphere and the ancestor of nearly all domestic ducks. On the measurements below, golden eagle 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

|  | golden eagle | mallard |
| --- | --- | --- |
| Mass | 2.8–6.7 kg | 0.7–1.6 kg |
| Length | 0.66–1.02 m | 0.5–0.65 m |
| Top speed | 45–320 km/h | 88 km/h |
| Lifespan | 15–38 yr | 3–29 yr |

## Where each one leads

- Mass: golden eagle is 4.1× heavier.
- Length: golden eagle is 1.5× longer.
- Top speed: golden eagle is 2.7× faster.
- Lifespan: golden eagle is 4.0× 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 golden eagle bigger than a mallard?

golden eagle is heavier — 2.8–6.7 kg against 0.7–1.6 kg.

### Who would win, a golden eagle or a mallard?

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.
