Abstract Almost every year the death or serious injury of Black Storks Ciconia nigra caused byoverhead electric lines is recorded in the Hungarian ringing database. Among the Black Storks with satellite transmitters from Hungary the prevalence of electrocution and collision with overhead electric wires is very high. This is a considerable threat not only near the breeding grounds but along migration routes as well. MME BirdLife Hungary has been working for years in order to decrease the risks posed by overhead electric lines, as the threat affects other species as well (including the White Stork Ciconia ciconia and different raptors). Communication and co operation with electricity providers and the importance of international co operation is also outlined.

Discussion ... As the majority of the data are originating from the ringing database and the registration of non marked individuals has only been possible in the past few years, it is very likely that the number of Black Storks that lost their lives because of OEL fatalities is much higher than registered. An important factor is that Black Storks usually use habitats distant from human settlements, this may also influence the number of registered cases as there may be numerous carcasses which are never found.
According to the analysis of the age distribution of these birds, we found that 64% of them died on their first migration, before leaving Europe.

Modelling risks posed by wind turbines and power lines to soaring birds: the black stork (Ciconia nigra) in Italy as a case study.

Abstract
Recent growth of investments in wind energy and power industries has increased concerns about the associated adverse impacts on wildlife. In particular, flying vertebrates are especially at risk, both directly, through an extra mortality rate due to collision with turbines and electrocution, and indirectly through habitat loss or fragmentation. In this study, we propose a modelling approach that combines species distribution models and data managed in geographic information systems to predict and quantify the effects of wind turbines and power lines on the breeding habitat of a soaring migratory bird, the black stork Ciconia nigra, in Italy. The species is recolonizing the country, where it had been driven to extinction in the Middle Age by human persecution. Today, infrastructures such as those considered in our study might in fact hamper this recolonization. Our results show a high probability of presence of the species in several areas in Italy. The most important variables in influencing habitat suitability for C. nigra are the mean temperature of May followed by the distance from urban areas, inland wetlands and hydrographic network. Exposure to wind turbine collision and electrocution resulted to be potentially high. In particular, in Northern Italy the main potential risk of mortality for C. nigra is posed by power lines, whereas in southern regions the species might be mostly threatened by wind turbines. Our approach makes it possible to detect suitable areas that, although not yet colonized by the species, would imply a high mortality risk should the species colonize them in the future. The tool we provide may therefore prove useful to conservationists and landscape planners in order to mitigate the impact of human infrastructures on this species and encourage a more sustainable planning
