A particularly scruffy juvenile black crowned night heron halfway through his moult I think.
It's not a cormorant--they've got those very distinctive curved beaks. *Could* be some kind of heron, but I don't think so. It's just really hard to tell because its OOF, AND because we don't really know where this picture was taken. The USA is a very big place; could you nail down where this is a bit more?
You mention water--river, lake, ocean?
