I hate to point out the ultimate irony, but it seems like there is an incredibly large amount of people here who are anti bird of prey, yet many are also smitten by this mating pair. Is it because they aren't troubling your birds? Bald eagles may be primary fishers, but they are opportunists too, and would take a chicken if given the chance. So if this pair was in your backyard, would you feel the same way? I have a family member who runs a trout farm. The local pair of bald eagles and their brood eat about 5K a year of trout, and the DNR won't allow him to use netting over the ponds. Why? The bald eagles might become entangled since they couldn't see it before they dove. Compare 5K to a few pet chicken losses..
I am glad that there are federal laws protecting them though. They are a very necessary part of the eco system which we often unbalance through needless killing.
