I took this picture last summer sometime in July at a cool wildlife Refuge called Pinckney Island just outside Hilton Head Island. Since then, I haven't been able to put my finger on it. It looks similar to a Great Blue Heron, but there are some key differences like the multi-colored bill/beak and weird legs. There's just something different about this bird. Oh, and if it helps at all, I do recall that day that this bird was chaperoning some youngster birds who weren't too old so maybe it has to be with the breeding season.
Let me know your thoughts! Thanks!
