I have a 16 foot plastic well pipe that has 10 bird feeders hanging from it as well as a couple of ground feeders below for the doves. I feed the hawks though not intentionally. They seem to be attracted to the doves more than the other birds although a blue jay gets caught once in a while.
There are a few bald eagles in my area as well but don't see them too often. They are a grand site.
