Résumé :	Though the Eagle Owl (Bubo bubo) was a widespread bird in Hesse formerly, it experienced a steep decline due to human persecution until 1910, when the last broods were observed. Only in the late 1970s the Eagle Owl be-an to return in its former breeding areas in Hesse - probably due to migration from adjacent Lower Saxonia, where Eagle Owls had been released in a reintroduction project since 1973. Since 1985 the population recovered rapidly and has currently reached more than 100 pairs. However man-made mortality is still high: Between 1972 and 2003 193 dead Eagle Owls were recorded. Among the mortality factors electrocution is ranking first with 40.8 % of all losses followed by road and railway casualties 30.4 %.
