Oyster-catchers—or sea-pies, to give them their old name, which is a very much better one—seem somewhat sleepy birds, unless it be that in the Shetlands birds sleep more in the daytime and less at night than farther south. Sleep, I think, it may be called, taking the attitude and the complete quiescence into consideration. Yet the red eye is always open, seeming—for you see but one—to wake singly, keeping guard over the rest of the slumbering commonwealth to which it belongs. But there is another eye, and that, no doubt, is open too. A pair of these quaint birds will often rest thus, side by side, upon the rocks, and another, seeing them as he comes flying along the dividing-line of shore and sea, will wheel inwards, and, settling beside them, be a lotus-eater too.
