Cool! Living in the Northwest, these are a pretty common sight for me, but I still love seeing them! But even here a nest is rare. You're lucky to have deciduous trees there so you can see it!
There's a bald eagle nest somewhere near the edge of a state park near my parents' home, but as almost all the trees are evergreen Douglas firs we've never been able to do more than see the parents and fledglings coming and going. It's really something to see a couple of eagles teaching their young to fly over your house. Before the eagles settled in the area, we would have young osprey flying over our house every summer, but now they stay on the other side of the lake to give the eagles room.
The fact that you've found a nest in Florida is really amazing to me, as it really wasn't that long ago that these magnificent birds were endangered. Makes me happy.
