What many people don’t understand about the birding situation in FL is that literally any place where one sees water, they will almost certainly see birds. It’s as close to a sure thing as one can get. Of course there are areas that are more photogenic than others (like all of those listed above and hundreds more), but birds are literally everywhere in the state. I should clarify my remarks a bit by mentioning that my preferred bird species for photography are water birds and raptors. There are hundreds of smaller birds that live in FL, (jays, buntings, cardinals, tits, etc), but I prefer the bigger critters.
As others have mentioned, if you desire useful info for a planned trip, you really do need to narrow down where you’ll be and what you want to see. It’s a large state area wise and unless you want to waste valuable time driving around, it’s probably best to narrow your trip to a relatively small area and then seek out those in the neighborhood who have hands on experience. I live in Sarasota on the west coast and I could keep you busy in a 100 mile radius for at least a week. Don’t try to see it all.
And, of course, if you do find yourself on the west coast of FL, don’t hesitate to pm me. I’d be delighted to set up some great itineraries.
Oh - I agree that Nov - April is generally the best time here for birding, but truth is there are birds here all the time, but hanging around outdoors between May and October is just plain unpleasant.
