The aim of this R&D project was to develop a specialist convention proposal for evaluating the species-specific effectiveness of bird protection markers on overhead power lines. In view of the expansion of the high-voltage and extra-high-voltage grid required in connection with the energy transition, there is a need for a comprehensible categorisation of the mitigation effect of bird protection markers in the upcoming approval procedures for bird species at risk of collision, especially those for which there is not yet any evidence backed up by studies. The methodological basis for considering the mitigation effect of bird conservation markers in planning and approval procedures in this specialist convention proposal is the assessment of the mortality risk from overhead line collisions in accordance with the methodology of the Federal Agency for Nature Conservation (BfN) by Bernotat & Dierschke (2016) and Bernotat et al. (2018). As part of this assessment procedure, the species-specific collision mitigation effect of bird protection markers is assessed in the reduction of the constellation-specific risk (CSR) when determining the so-called constellation-specific risk (conflict severity in each individual case). The content of this technical convention proposal is therefore the fundamental species-specific assessment of the effectiveness of bird prot
