Bald eagles were once so abundant that they were viewed as pests. Early Americans tried their best to get rid of them.
In the post-WWII era a chemical called DDT wreaked havoc on them. It didn't hurt the adults, rather it made their egg shells too thin. They were almost rendered extinct.
They were just recently taken off the endangered species list and most Americans have not seen one. Good news is that populations is growing. So, yeah, Americans tend to get excited when they finally see one.
In Alaska they are so abundant that, unsurprisingly, they are viewed as pests. They're known for bothering people.
Other birds of prey that are noteworthy are Peregrines. Everyone was worried about their numbers but they found a niche that no one expected. Turns out, they love skyscrapers and can survive well in major cities. NYC has a bunch.
