Background The spread and profusion of electricity power lines makes them a serious threat for a wide range of bird species, including up to 7% of the Species of European Conservation Concern. Birds are at risk due to collisions with wires and electrocution. Based on the experience of other EU countries, high voltage power lines are the most significant threat, especially for heavy bodied and large soaring bird species. Preventing electrocution on power lines is possible, with the installation of electrocution-safe measures, although collisions cannot be completely eliminated. Objectives The project aims to improve the conservation status of the migratory, wintering and some breeding bird species occurring in Lithuania, through a reduction in the negative impact of high voltage overhead electricity transmission lines on their populations. Specific objectives are to: Reduce significantly bird mortality rates due to collisions with electricity lines by using special installations on the wires of high voltage electricity transmission lines; Reduce significantly white stork (Ciconia ciconia) mortality rates due to electrocution, through the installation of protective devices on the pylons of high voltage overhead electricity transmission lines; Support the breeding population of the common kestrel (Falco tinnunculus) and other falcons, through the implementation of supportive conservation measures; Evaluate the effectiveness of the conservation actions carried out through the establishment and implementation of a monitoring programme; and Increase public awareness of the problem of bird mortality due to high voltage electricity transmission lines. Expected results: At least 7 100 ‘spiral‘ type and 1 500 high-visibility wire markers erected as bird flight diverters on at least 108 km of high voltage electricity lines in 18 selected sites; At least 6 000 ‘wishbone‘ and 6 000 ‘saucer‘ type installations erected on 1 200 utility poles in different areas of Lithuania for the protection of the white stork; and At least 500 nest-boxes for falcons located on overhead electricity line pylons in different areas around the country.
