Not all propaganda is untrue. Sometimes it is more tactical. In this case, implying one true thing is more important than it is.

All construction projects of all types have been having impacts on the animals that are displaced or effected for a while, and we do need to have concern for it and change many things, from infrastructure designs to materials used and how they are manufactured.

But inflating this concern over these birds related to windmills is intended to bring hesitation to people who are concerned about the environment that would otherwise support these necessary changes to our power grid.

There will always always always be less damage to environments from windmills than there is from equivalent power fossil fuel use. Implying otherwise is dishonest. Look at any image of a strip mine and tell me that causes less damage than windmills
