The chick can dive as easily as the grown bird, but one may watch these family excursions for a long time without once seeing either of them do so. Instead, they now merely duck to get the seaweed, which almost reaches the surface. The chicks, however, are often raised by the swell of the sea beyond the height at which they can nibble it comfortably, and it is then funny to see the hinder portion of their little bodies sticking up in the air, with their legs violently kicking, as they hold on with might and main to prevent being floated off on the wave. Sometimes a brisk one bids fair to tilt them right over, but they always ride it in the most buoyant manner. The motion with which they do so—or rather with which it is done for them—is sometimes very curious, for they look as though they were swung out at the end of a piece of elastic, and then drawn smoothly back again, just as they are on the point of turning a somersault; but more often it is a plain bob-bobbing.
