What the Pied-billed Grebe sounds like

A pudgy, short-necked grebe that looks more like a floating brown nugget than a sleek waterbird. In breeding plumage it sports a stout, whitish bill neatly encircled by a black band— the "pied" that gives the species its name. Often seen alone, it prefers to dive rather than fly when frightened, sometimes sinking out of sight without a ripple.
