| Abstract | ||||
| Wind farms along bird migration routes may be very hazardous. During the spring migration season in 2020, a study on the collision of bat and bird species was carried out on the KFW 240 MW (120 WTGs) wind farm. Direct inspections by searchers and unsystematic line transect searches with autos were used in the carcass searches technique. To examine the collected data, the GenEst estimator was used. During a systematic search, six bird carcasses/remains were discovered, three of which belonged to migratory soaring birds (MSB) with the least concern status. During the unsystematic search, two MSB and one Passerine carcasses were discovered, but no bat carcasses were found as collision victims. Furthermore, no bird or bat carcasses were detected beneath the high voltage powerlines that run parallel to the wind farm. Carcass persistence trials revealed that MSB lasted 23.92 days while little passerines lasted 3 days. The detection probability for all decay types was 87.2, 93.3 % for MSB, and 41.9 % for tiny Passerines. Moreover, the final fatality estimation for the plant and its structures was 0.084 MSB fatality/ turbine/ season, 0.166 Passerine/ turbine/ season | ||||
