Why Do Ducklings Paraphrase in a Line? The Fluid Dynamics of Broods
1. Wave Interference & Drafting
When Mother Duck swims, she produces bow and stern wake waves. Trailing ducklings ride the destructive interference wave crests, reducing hydrodynamic resistance up to 63%.
2. Reynolds Steering & Separation
Each duckling balances three autonomous vector rules: cohesion (pull towards the clutch center), separation (avoid trampling siblings), and alignment (matching the leader's velocity).
3. The Quack Rally (Acoustic Cohesion)
When separation exceeds safety margins, maternal acoustic calls override wandering curiosity, creating high-priority steering vectors that snap ducklings back into single-file order.
