Power lines and birds: An overlooked threat in South America

Abstract

Overview

Power lines pose a significant hazard to bird populations globally, leading to numerous fatalities through electrocutions and collisions each year. This issue has broad implications, especially for the survival of threatened species.

Context

In South America, despite the documented global threat, localized studies and data remain limited. This review synthesizes available scientific and anecdotal evidence, supplemented with new data from citizen science contributions, electric companies, and field monitoring.

Findings

• While data is still sparse in South America, the existing evidence indicates a widespread threat to various bird species, including those under severe threat.
• Crucial data such as species most affected, number of individuals impacted, and high-risk areas remain poorly documented and mostly anecdotal.

Conclusion

Given the biodiversity hotspot that South America represents, featuring numerous threatened and endemic species, the urgency for comprehensive conservation measures is paramount. Prioritizing the avoidance of power line installations in key areas and implementing effective mitigation strategies is essential. Further, adaptation of existing infrastructures and the incorporation of protective measures in new projects are crucial steps that could significantly reduce wildlife impacts.
