My parents lived in a small village in Alaska in the 1990s. Much too small to have a McDonalds or even dumpsters. They had resident bald eagles in the same way many cities have pigeons. That entire region of North America has always been like this. They’ve culled hundreds of thousands of the birds over the last century because they can become a nuisance, particularly if over-populated. They’ll eat anything that looks like meat.
In the same way, the brown bear is almost non-existent in its native range in the contiguous US, but abundant further north. The bald eagle gets somewhat special treatment because it is a national symbol.
