It could be illegal actually. Even if you install some obstacle near eagle's nest I heard you can be criminally charged. But if you install power lines and eagles kill themselves or you poison some animals and eagles die from eating them you are in the clear

Only if you do it with the intent (or prior knowledge) that will happen.

If they just like suiciding against a specific window of yours for no apparent reason, then you’re fine.

Not really. If you build this window or whatever close enough to eagle base and eagle dies on it incidentally or it is found to be simply disturbed by it you are still criminally liable

https://www.fws.gov/program/eagle-management/eagle-incidenta... I hope you didn't disturb any eagles lately;)

(Unless you have a permit. If you are powerline company you are allowed unlimited incidental kills for example. Or if you are wind power company you can apply for a permit for thousand incidental kills or something)

Having read through that, there is zero chance you could actually violate that doing any sort of reasonable or normal construction.

Or do you have an example where someone built a house in a reasonable fashion, an eagle ran into it, and the owner or construction company was charged?

You’d have to build right next to an active nest, or intentionally design the building to be a hazard in an area they were nesting/living. Which goes to my comment.

If you unintentionally violate a law it does not mean you're not guilty. Which goes to my comment. "if a bird kills itself, that isn’t illegal" is simply false per this law.

Even if the bird doesn't kill itself but simply judged to "can't reproduce" due to your intentional or unintentional action you are guilty.

If you think this is illogical and unenforceable welcome to the club;)

You literally did not address any of my points. The law does not say what you seem to think it says either.

I addressed all of them. Ignorance of the law is not an alibi. Even removal of potential eagle habitat which building a house in the wrong place could be is a violation. Even without causing any incidental kills or disturbance. Read it! It's fun.

And do you have any examples of that ever actually happening? Like I asked, and you completely ignored?

You can make your own conclusions how often it happens. Add poisoning eagle through poisoning their prey which also falls under this law and guess how often that happens. Then guess how often it is prosecuted.

So ‘trust me bro, it happens’?

Does the pope shit in the woods? I don't monitor 24/7 to check but my logic probably says yes. What's your logic about this law? But don't mistake absence of evidence for evidence of absence.

(Also you can find interesting stuff like https://www.smithsonianmag.com/smart-news/study-finds-rat-po.... Is this illegal? By law totally yes in at least 4% cases of those dead eagles are illegal incidental kills without permit and others are at least disturbance. How many people prosecuted? I count grand total of zero.)
