Memory of the Cereopsis Goose. Keeper Atkin also showed me an instance of the wisdom of the cereopsis geese, from Van Diemens Land, South Australia. During the winter those birds are kept in the Wild-Fowl Pond; but in summer they are quartered in a secluded yard of the Crane's Paddock, nearly half a mile away. Twice a year these birds go under their own steam between those two enclosures. When turned out of the Cranes' Paddock last November they at once set out and walked very briskly southward up the Bird's Valley, past the Zebra House. On reaching the Service Road, a quarter of a mile away, they turned to the left and kept on to the Wolf Dens. There they turned to the right and kept on two hundred yards until they reached the walk coming down from the Reptile House. There they turned to the left, crossed the bridge, stopped at the gate to the Wild-Fowl Pond enclosure, and when the gate was opened they entered and declared themselves "at home." Mr. Atkin says that in spring these birds show just as much interest in going back to their summer home. Falconry. We cannot do otherwise than regard the ancient sport of falconry as a high tribute to the mental powers of the genus _Falco._ The hunting falcons were educated into the sport of hawking, just as a boy is trained by his big brother to shoot quail on the wing. The birds were furnished with hoods and jesses, and other garnitures. They were carried on the hand of the huntsman, and launched at unlucky herons and bitterns as an _intelligent_ living force. The hunting falcon entered into the sport like a true sportsman, and he played the game according to the rules. The sport was cruel, but it was politely exciting, and it certainly was a fine exhibition of bird intelligence. Part of that intelligence was instinctive, but the most of it was acquired, by educational methods. Outstanding Traits in a Few Groups of Birds. In creatures as much lacking in visible expression as most birds are, it is difficult to detect the emotions and temperaments that prevail in the various groups. Only a few can be cited with certain confidence. Vanity Displays in Birds. The males of a few species of birds have been specially equipped by nature for the display of their natural vanity. Anyone who has seen a Zoological Park peacock working overtime on a Sunday afternoon in summer when the crowds of visitors are greatest, solely to display the ocellated splendor of his tail plumage, surely must conclude that the bird is well aware of the glories of his tail, and also that he positively enjoys showing off to admiring audiences.
