CROWNED CRANE.
The feathers of the Crest of this bird look not unlike stiff hairs.

AUKS, GULLS, AND PLOVERS.
THE AUK TRIBE.
The Guillemot is found all around Britain, and breeds wherever the sea is fringed by cliffs affording ledges for the reception of the eggs. It breeds in colonies often numbering many thousands, and lays but one egg, which is large and pear-shaped. Since the guillemot builds no nest, but lays its egg on the bare rock, this peculiar shape is advantageous, since it revolves on itself, when disturbed, instead of rolling off the ledge into the sea. At the same time thousands of eggs fall into the sea every year owing to the bird's leaving the egg, whilst incubating, in too great a hurry. At Lundy Island one of the sources of amusement for the gaping tourist was that of firing a shot to frighten the birds, with the result that, at each shot, showers of eggs were knocked off the ledges on to the rocks below. The colour of the egg varies infinitely, no two being quite alike. This, it has been suggested, is useful, as the mother is thereby enabled to identify her own egg, even when surrounded by hundreds of others. The young are covered with long down, and when big enough, but still unable to fly, are taken down by the mother to the sea, being carried, some say, on her back: others say the chick is seized by the wing and carried down.
