I agree with Ruralchill's IDs. As for distinguishing Great and Double-crested, I believe all Greats have a small white patch at the top of their their throat just beneath the chin. They are also bigger (but that's not much help unless you see both species together). Greats are uncommon in Florida except for the far northeast coast in the winter, although you might rarely spot one on some other part of the Florida coastline. As for the neck color, juveniles of both species have lighter colored necks.
