# Common Loon vs Great Crested Grebe: Who Would Win?

Common Loon vs Great Crested Grebe is too close to call. Our 3-round simulation gives Common Loon a 49% chance and Great Crested Grebe 51%, which is not enough for either to claim the win.

Both are at home in rivers and wetlands, so the simulation's neutral ground is close to where they actually live.

## Verdict: Too close to call
- **Win probability**: Common Loon 49%, Great Crested Grebe 51%
- **Decisive weapon**: Evenly Matched Evolutionary Countermeasures

### Round 1: Opening Clash & Speed

Common Loon seizes the opening initiative with superior agility (44 vs 39), circling Great Crested Grebe and striking from an advantageous flank.

### Round 2: Clash of Superpowers

Great Crested Grebe detonates its biological specialty: A head-shaking courtship duet that can include a breast-to-breast 'Penguin-dance'. The sheer destructive payload overcomes Common Loon's 22 armor rating.
