The conservation of birds is one of Viesgo’s major environmental objectives. One of the main actions that we carry out in our power lines in areas such as the Marismas Negras y Blancas de Astillero, in Cantabria, is the installation of bird-guards : beacons with which we help prevent collisions birds thanks to the visibility they provide over overhead power lines.

With SEO BirdLife , the main Spanish ornithological NGO, we collaborate in various projects, such as the MIGRA program , which started in 2011 and aims to study migration of birds in Spain. Our participation in the framework of this program is mainly focused on the marking of the common tern, which is carried out with a new nano-GPS system, and on the conservation of the common kestrel. Both species are present in Cantabria, especially in the Bay of Santander.
