Mannar – Three greater flamingos died recently after striking overhead power lines in the lagoons of northern Sri Lanka. Necropsies confirmed that the birds’ long necks were severed mid-flight rather than through electrocution. The incidents have drawn fresh attention to the risks facing the migratory flocks that support local tourism each year.
Recent Fatalities Prompt Fresh Scrutiny
The Department of Wildlife Conservation conducted examinations that ruled out electrocution as the cause. Instead, the cables acted like blades against the birds during low-light flights at dawn and dusk. Conservation groups note that similar infrastructure pressures are growing across the wetlands, including proposed wind energy developments near the Vankalai Sanctuary.
Local tourism relies heavily on the annual arrival of pink and white greater flamingos. Visitors travel to the region specifically to view the large flocks against the lagoon backdrop. Any sustained decline in bird numbers could reduce that draw and affect businesses that have built around the spectacle.
Biological Traits Increase Collision Risk
Ornithologist Sampath S. Seneviratne of the University of Colombo explained that flamingos possess limited maneuverability because of their size and wingspan. They often travel in dense groups during periods of reduced visibility, which compounds the danger near power infrastructure. These traits make the species especially prone to strikes compared with more agile birds.
The same vulnerabilities have produced documented losses elsewhere. Reports from South Africa recorded 464 flamingo deaths linked to power lines between 1997 and 2019. A separate study in India’s Gujarat state counted 76 fatalities from wire collisions over a three-year period in the early 2000s.
Energy Expansion Raises Long-Term Concerns
Planners continue to advance renewable projects in the Mannar area, where wind resources are strong. Conservationists argue that routing decisions must account for established flight paths used by the migratory birds. Without adjustments, additional lines and turbines could multiply the existing hazards.
Authorities have begun reviewing mitigation options such as line markers or underground segments in sensitive zones. Early intervention could limit further losses while preserving the habitat that draws both birds and visitors.
What Matters Now
- Three confirmed flamingo deaths from power line collisions in Mannar lagoons.
- Necropsies showed severed necks rather than electrocution.
- Flamingos’ flight patterns and body structure heighten collision risks.
- Comparable fatalities documented in South Africa and India.
- Proposed wind projects add pressure on the same wetlands.
The recent deaths serve as a clear signal that infrastructure planning and wildlife protection must be coordinated more closely. Continued monitoring and targeted adjustments offer the best path to keeping Mannar’s flamingo spectacle intact for future seasons.
