New study: How to stop birds from getting electrocuted by and colliding with power lines across the EU
A new study commissioned by our German Partner NABU, and compiled by Raptor Protection of Slovakia, provides an overview of the many solutions available to protect birds from getting electrocuted by, and colliding with, powerlines across Europe.
NABU estimates that in Germany at least 1.5 million birds annually die after colliding with medium and high-tension grid lines.
Large species, especially soaring birds like the Eastern Imperial Eagle (Aquila heliaca), Saker Falcon (Falco cherrug), White Stork (Ciconia ciconia), and Eurasian Buzzard (Buteo buteo) and many other species can be killed by electric shocks on specific unsecured types of masts. The bird might be electrocuted by completing an electrical circuit, simultaneously touching two energized parts, or an energized part and a grounded part. This could happen when the bird for example stretches its wings and touches two wires.
Birds collide with overhead lines when they fail to see the cables in time. Collisions are more likely to occur with the overhead static wire, which is less visible than energized lines due to its smaller diameter. Swans, other waterfowl, and large fast-flying birds are the most common victims.
But all this can be avoided. In this new study, all the technical solutions available are shown and evaluated. By following these guidelines, power lines can be an enemy of the past for birds. In a significant number of countries, NGOs and electric companies have joined forces to implement safe practices with great success. They are a testimony to how people and nature can thrive together.
Creating bird safe powerlines is not only important to protect birds, but it is also safer for companies and humans. Bird collisions and electrocuted birds can cause power cuts, power outages, and start fires during periods of drought.
The consistent use of the best existing technical solutions, accompanied by legal obligations and control in all EU countries, enables the compatibility of bird protection and the necessary expansion of the power infrastructure.
BirdLife calls on the European Commission to develop technical standards on how to avoid the electrocution and collision of protected birds. These EU standards would raise the political recognition of the problem and increase the implementation by the network operators. Most helpful would be a uniform European standard. Many of the measures collected can also easily be implemented on migratory routes in the Mediterranean or in African wintering areas.

Twice a year, billions of migratory birds embark on incredible journeys across the globe. These birds follow specific routes called flyways, which act as super-highways in the sky. Their journey takes them south for the winter and back north in the spring to breed.
Today, BirdLife International released the European Red List of Birds 2021. The Red List reviews the regional extinction risk of 544 bird species in over 50 countries and territories in Europe and follows the IUCN Red List Categories and Criteria applied at regional level. Each species extinction risk is evaluated from ‘Least Concern’ to ‘Extinct’.
