Abstract

Overview

The concept of avian magnetic orientation is well-documented across various studies, yet the role of magnetic clues in guiding homing pigeons is still debated. This study delves into the magnetic orientation of homing pigeons by investigating their performance in races correlated with geomagnetic disturbances.

Findings

  • Evaluation focused on the homing speed of pigeons during races alongside specific geomagnetic indices.
  • Data from approximately 289 pigeon races spanning over 15 years revealed minor negative correlations between geomagnetic fluctuations and homing time.
  • This suggests that natural magnetic variations may influence the navigational capabilities of pigeons.

Conclusion

The results underscore the potential impacts of geomagnetic disturbances on pigeon navigation. Further research could explore this phenomenon as pigeon races offer a regular and widespread platform for study, presenting an opportunity to test various environmental influences on avian navigation.
