# cougar vs golden eagle

**cougar vs golden eagle: Evenly matched on the numbers**

Measured comparison — not a prediction

The widest-ranging land mammal in the Americas; despite the size it is more closely related to the domestic cat than to lions. One of the most widely distributed eagles, and a bird flown in falconry for two thousand years. The measurements below split evenly, which is rarer than it sounds.

## The measurements

|  | cougar | golden eagle |
| --- | --- | --- |
| Mass | 29–100 kg | 2.8–6.7 kg |
| Length | 1–1.8 m | 0.66–1.02 m |
| Height | 0.6–0.8 m | — |
| Top speed | 80 km/h | 45–320 km/h |
| Lifespan | 8–20 yr | 15–38 yr |

## Where each one leads

- Mass: cougar is 15× heavier.
- Length: cougar is 1.8× longer.
- Top speed: golden eagle is 3.0× faster.
- Lifespan: golden eagle is 2.0× 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 cougar bigger than a golden eagle?

cougar is heavier — 29–100 kg against 2.8–6.7 kg.

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

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.
