Corneal opacity in Northern Bald Ibises (Geronticus eremita) equipped with radio transmitters

Abstract

Overview

This note discusses findings related to corneal opacity in Northern Bald Ibises (Geronticus eremita) suspected to be caused by radio transmitters equipped for biologging.

Findings

• Researchers observed unilateral corneal opacity in populations of Northern Bald Ibises.
• The birds were part of a reintroduction program in Europe and were equipped with solar radio transmitters.
• Electromagnetic radiation from the GSM module of the transmitter is proposed as a causal factor.
• Potential effects include both thermal and non-thermal impacts on corneal tissue.

Conclusion

The study highlights the link between electromagnetic radiation exposure and adverse biological effects, suggesting persistent low-level exposure could have subtle and insidious impacts.
