In the current scenario where biodiversity conservation is becoming increasingly urgent, initiatives such as the LIFE PowerLines4Birds project are emerging as fundamental pillars in the protection of birdlife. The project aims to reduce the impact of power lines, focusing on seven threatened species:
Combining science and conservation, the project seeks to identify and implement effective mitigation measures to reduce the risk of mortality from collision and electrocution on power lines.
Over the last few months, the project’s technical team has been engaged in intensive field work in critical areas for the target species, particularly in the Special Protection Areas (SPA) of Castro Verde, Vale do Guadiana, Moura/Mourão/Barrancos and Campo Maior. By collecting and analysing evidence of mortality (such as bones, carcasses and feathers), the team investigates the behaviour and interaction of birds with high and medium voltage power lines.
By doing so, it identifies critical lines for correction and monitors the effectiveness of the mitigation measures implemented. During data collection, the project’s technicians observe not only the characteristics of the power lines, but also the surrounding habitat. Factors such as the type of vegetation, the presence of predators and migratory routes are assessed, as they play a role in the dynamics of interactions between birds and these human infrastructures.
Birds play a crucial ecological role, but many, like the species targeted by this project, are threatened. Habitat loss and mortality caused by human infrastructure are the main threats. Power lines in particular pose a risk to birds, both through collision (when they hit the line during flight) and electrocution (when they land on the pylon or the line, they touch two electrified points when taking off). Therefore, initiatives that mitigate these impacts are essential to guarantee the preservation of birdlife.
Using data obtained from power line monitoring, the LIFE PowerLines4Birds project team will assess the effectiveness of different mitigation measures, both for collision and electrocution. The measures include devices such as bird flight diverters and insulated structures. New innovative methods will also be tested, such as the eco-cross bar and underground power lines in a rural context.
The success of this work depends on the cooperation of several environmental NGOs with energy companies. Biologists, engineers and the community working together can accelerate the implementation of essential solutions to ensure that birds can safely coexist with electrical infrastructure.
Another crucial aspect of the project is training and raising awareness among the different stakeholders, but also among the local communities. The LIFE PowerLines4Birds project encourages community participation in monitoring efforts and is launching an appeal for volunteers interested in collaborating with the project. Following previous training sessions, more will take place until the end of the year, targeting different entities, such as consulting professionals, GNR and environmental NGOs. Keep an eye on the calendar!
The LIFE PowerLines4Birds team reaffirms LPN’s commitment to bird protection. This work is not only of scientific interest, but a true call to action in defense of nature. With continued efforts and a collaborative approach, we are on the right track to mitigate the negative impacts of power lines on birdlife. With every piece of data collected and data analyzed, the team is one step closer to implementing changes that can ensure a safe future for birds.

In addition to presenting the objectives, actions and expected results of the project, this session allowed the exchange of ideas and the clarification of questions between the participants and the fundamental entities in the conservation of the project's target species.
