<u>Mistake of ignoring secondary effects</u>
Explanation:
Whenever there arises an adverse impact of a policy and it's implementation, owing to ignorance of secondary consequences, it is termed as ignoring secondary effects.

In the given case, the environmentalists have only considered the generation of alternative sources of energy via windmills which will lead to preservation of fossil fuels. The proposed policy has been implemented without taking into account it's flip side i.e the harm it causes to bat population and migratory birds.
Thus, it can be stated that the environmentalists herein only considered the favorable outcome of a policy implementation and ignored the adverse effect of the same. Hence, they are said to have committed the mistake of ignoring the secondary effects.
