As the Audubon Society notes, the number is dwarfed by the number of birds killed by house cats and building collisions. But there are even greater threats to birds, like increased use of pesticide and above all - climate change. Stopping wind power expansion because of the birds that die in collisions is like not extinguishing a building on fire because of fears of the damage the water will do to the building. That said, many laws include provisions to minimise the harm to birds and bats. Including the German one under discussion.
