Abstract

Overview

The light-dependent magnetic compass sense of night-migratory songbirds can be disrupted by weak radiofrequency fields, suggesting concerns over environmental electromagnetic noise and its effects on wildlife.

Findings

  • Exposure to 75–85 MHz radiofrequency fields affects the magnetoreception in birds through a flavin-based radical pair mechanism.
  • Quantum-chemical calculations imply that identifying the sensitivity of these radicals dnes information about potential environmental safety thresholds.
  • Impact on Avian Navigation: Extensive behavioral experiments demonstrate that even minimally invasive electromagnetic fields can significantly disturb natural behaviors like magnetoreception.

Conclusion

These scientific findings indicate a direct link between electromagnetic field exposure and disruption in natural wildlife behaviors, suggesting potential risks to biological mechanisms sensitive to low-level electromagnetic noise.
