The technique of the artful crash: To float along, eyeing the blue depth just below the surface until the goal is within sight. And then, to roll over, head braced - wings folded back, body streamlined and smash into the blue resistance. Perchance the aim was true and the impact undeviating and a meal is gained, if only a couple of morsels for the work.
There has got to be a better way to get a meal!
