# bald eagle vs peregrine falcon

**bald eagle vs peregrine falcon: bald eagle leads on 3 of 4 measures**

Measured comparison — not a prediction

The national bird of the United States, recovered from about 400 nesting pairs in 1963 to over 70,000 today. The fastest animal on Earth, reaching over 320 km/h in a hunting stoop. On the measurements below, bald 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

|  | bald eagle | peregrine falcon |
| --- | --- | --- |
| Mass | 3–6.3 kg | 0.33–1.5 kg |
| Length | 0.7–1 m | 0.34–0.58 m |
| Top speed | 56–160 km/h | 90–390 km/h |
| Lifespan | 15–38 yr | 8–19 yr |

## Where each one leads

- Mass: bald eagle is 5.0× heavier.
- Length: bald eagle is 1.9× longer.
- Top speed: peregrine falcon is 2.0× faster.
- Lifespan: bald eagle is 1.5× 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 bald eagle bigger than a peregrine falcon?

bald eagle is heavier — 3–6.3 kg against 0.33–1.5 kg.

### Who would win, a bald eagle or a peregrine falcon?

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.
