There are primarily three important questions regarding offshore wind turbines that this study was required to answer: Which flight altitudes do waterfowl use during their migration over open seas and at night as well as in conditions of poor visibility? How high do songbirds (passerines) fly over the sea at night and in conditions of poor visibility? How do both waterfowl and songbirds react under conditions of poor visibility when they come close to off-shore wind turbines? An understanding of these matters is very important in order to calculate the risk of birds colliding with off-shore wind turbines. The knowledge can be used as a basis for planning, licensing and environmental impact assessments concerning offshore windparks. _ _ _ A report from the Vindval research programme.
