The Common Guillemot (<i>Uria troile</i>) is a member of the auk family. It breeds on all rocky coasts of the North Atlantic. The bill is long, straight, and strong, the wings and tail short. In spring, the upper surface of the body is brownish black, the under white, save for the dark throat; in winter, the throat becomes white or mottled. All guillemots lay a single pear-shaped on the ledge of a sea-cliff. They make no nest whatever, and large colonies brood in company.

"The Flying fish, with wings expanded and elevated in the act of flight. This anomalous and interesting creature is adapted both for swimming and flying. The swimming-tail is consequently retained, and the pectoral fins, which act as wings, are enormously increased in size."&mdash;Pettigrew, 1874

Also known as a Solan Goose (Sula bassana), the Gannet is a large marine bird which nests in scattered localities in most parts of the world. Its specific name refers to the fact that it has long been a denizen of Bass Rock -- a famous craggy islet on the coast of England. This bird also nests on Bird Rock in the gulf of St. Lawrence, and other species exist in the tropics. It belongs to the same sub-order as the cormorant, and may be recognized by the fact that, as in the latter, all four toes are united by a web. 

Its bill is long, strong, and compressed to a point. In adult life, the plumage is white, save for the black primaries and a buff patch on the head or neck; the young are dusky, and do not acquire the white plumage until their sixth year. Their nests contain only one egg.

The Goshawk (Astur palumbarius) is a hawk abundant in the forest regions of northern Europe and Canada, but rarely seen southward, except occasionally in winter. The upper part of the body is ash-brown, with four broad dark bands on the tail; the under part white, barred with black. The bird is bold and rapacious, and remarkable for the skillful turns by means of which it follows every movement of the quarry. It was one of the favorite hawks in falconry.

In heraldry, the griffin is a fabulous animal, with the head and forefeet of an eagle, and the body, hind legs, and tail of a lion. The head is represented with pricked ears, symbolical of its vigilance. In mythology, the griffin was a creature similar in form to the griffin of heraldry, which was supposed to find its especial function in watching over hidden treasure, especially in Scythia. It was dedicated to the sun-god Apollo, whose chariot appears in early art as drawn by griffins. It was a favorite ornamental 'theme' in ancient Babylonian and Persian art, and is also found in a similar way on art objects of the Phoenicians, the Mycenæan civilization, and the ancient Greeks. The Romans and art-workers of the renaissance used it as a purely decorative device.
