At the Gulf Coast Visitor Center we saw a group of three American Eagles perched upon a tree. This one flew across to another tree limb. They are not as good hunters as Ospreys and are known to loot from the Ospreys.
The Mangroves Boat tour through the low lying mangrove trees is serene. It could get only better if you could do it on a canoe. You could see a whole variety of water birds, Dolphins and Manatee.
