I can't identify the tree other than to say it's an oak and most likely live, laurel or water. But the clumps you are seeing are spanish moss and not affiliated with the tree.

I don't know what kind of tree your camera might be pointing at, but doesn't appear to be Quercus virginiana (Live Oak). I agree with musical that you are assuming that the Spanish 'Moss' is part of the tree, when in fact, it is simply using the trees as a support system. SM can grow on a chain link fence.

It's a coastal bromiliad.

Thanks musicalperson and rhizo. We've been going to MB for several years now. I probably see this spanish moss every year we go down, but by the time I get home, I've forgotten about it. I think I've seen it on some trees resembling crepe myrtles also. I actually did think it was part of the trees.

Flowering plant in the pineapple family. If you look at the right time you can see the tiny flowers.
