The aim of the project is to study the potential effects of offshore wind turbines on migratory birds and passage migrants.
In recent years, knowledge about this has already been significantly increased through several research projects. In relation to individual species, however, knowledge about the circumstances of collisions, possible small-scale evasive movements to avoid collisions or species-specific attraction effects is still insufficient. TRACKBIRD aims to further close this data gap. For this purpose, state-of-the-art techniques are used that enable small-scale tracking of single individuals of various potentially endangered bird species. Based on this data, flight paths and conditions under which bird migration over the sea occurs at an increased rate will be examined more closely, thus enabling a better assessment of the spatial and temporal endangerment situation of these species in relation to offshore wind power.
The aim of the project is to develop the missing knowledge of the spatio-temporal distribution of migratory events over the North Sea and the Baltic Sea, which is necessary for a technically sound assessment of the effects of offshore wind turbines on migratory landbirds and waterbirds (e.g. collision risk). The investigations are to build on the experience, findings and preliminary work of the BIRDMOVE R&D project.
On the one hand, the flight paths of songbirds of other selected species individually equipped with micro-transmitters to the sea and back to the mainland are to be determined using the network of receiving stations (antenna systems) established in the North Sea within the framework of BIRDMOVE. Secondly, the flight paths of selected, larger land and water bird species migrating over the sea are to be analysed at the Baltic Sea with high temporal-spatial resolution using modern GPS technologies (GPS data loggers with GSM function).
In addition, the evaluation of already collected data on the flight paths of individual birds will be continued.
