Kalocsa, B., Tamás, E. A. (2021). The hazards of overhead electric lines to Black Storks Ciconia nigra. SIS Conservation, 2021, 3, 40‐43. ISSN 2710‐1142 (online)
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.
