Common Buzzards keep continuing to be the most numerous victims of medium voltage pylons, along other strictly protected species, like those two satellite-tagged Imperial Eagles that were electrocuted in the past few weeks.
Electrocution is the single biggest threat to several protected and strictly protected bird species worldwide, therefore, conservation experts deal with the issue and its possible solutions as a highly important one. Endangerment through short-circuits caused by birds is not restricted only to birds, but also to electric companies and indirectly to lots of consumers.
MME/Birdlife had launched its Medium Voltage Pylon Survey helped by bird conservationists and volunteers in 2004 in order to obtain data collected with an uniform method. After analysing the data, we can get an idea of the scale of the electrocution. Since, there are about 700.000 medium voltage pylons in Hungary, it requires several years of hard work. We have detailed data about 56.667 pylons altogether with results from previous surveys. The coordination of the survey of 2012 is done within the framework of the „Bird protection without borders” (HUSK/1101/2.2.1/0336) project, while the field surveys mainly sponsored by the Saker Falcon Life+ (LIFE09NAT/HU/000384) and the Környezet és Energia Operatív Program (KEOP). This year, volunteers and colleagues of the National Park Directorates and MME/Birdlife surveyed 6911 pylons and found 377 dead birds of 19 species. Nature conservation organizations and electric companies had collaborated to change existing pole head configurations to bird-friendly, however, these modifications take a long time and sometimes birds still die by electrocution under retrofitted pylons due to the use of unsuitable technologies.
Electrocution pose the biggest threat to species readily perch on pylons and whose populations in Hungary make up an important part of the whole European populations. These species are the Imperial Eagle, Saker Falcon, and the Red-footed Falcon, moreover, based on data obtained in the 90s, the human induced mortality of the White Stork can be attributed to electrocution. Surveyors found lots of carcasses of birds under checked pylons this year, as well. Estimates suggest that several tens of thousands of birds die by electrocution every year. Common Buzzards are on the top of the list just like in the previous years, but other species were found too.
Deaths of those satellite-tagged young Imperial Eagles, which were marked by MME/Birdlife within its Life+ project, are particularly hurting. Two of the tagged ones, named after London Olympic medallists, were found dead in the past few weeks. Krisztián (named after Krisztián Pars and Krisztiána Berki) was found by colleagues (after alerted by MME) of the Turkish Birdlife partner organization Doga Dernegi near the Syrian-Turkish border. Éva (named after Éva Risztov) was recovered by associates of the Körös-Maros National Park on December 16th. Satellite transmitters were big help in finding the carcasses, otherwise we may have never found out about it. Electrocution, as the most possible cause of death, was confirmed by the signs at the scene and Krisztián’s case proved the importance of an international cooperation.
