It appears that this Great Blue is wet and drying its wings. I've seen these birds wading into water above their knees before, but not in high enough to get soaked. The Great Blue is a wading \bird, not a diving bird.
The one above is in the mangrove tops at Quick Point.
I've seen a Great Blue with his wings in this position here once before.
