In late 2023, experts from the Bulgarian Society for the Protection of Birds and Elektrorazpredelenie Yug EAD made history by installing reflective markers for birds, known as diverters, along a 20 kV overhead power line. This groundbreaking initiative, the first of its kind in Bulgaria, utilized drone technology for the installation.
23 Great white pelicans and 15 Dalmatian pelicans were found dead during the field survey of the power lines, made by the Bulgarian Society for Birds Protection (BSPB) in Bulgaria. The experts recommend taking immediate mitigation measures to prevent the further deaths of these rare birds.
On the 10th of December 2021 “Maria”, the first Dalmatian pelican with a satellite transmitter in Bulgaria, has died. The cause of death was a collision with the overhead powerline.
During June, waterbirds belonging to protected species were discovered dead on three occasions, due to collision with power lines inside the protected area of the Mesolonghi Lagoon National Park, western Greece.
