The Japanese Sika Deer, (_Cervus sika typicus_), is a small representative of a large group of deer species inhabiting far-eastern Asia, and known as the Sika Deer group. A ridiculous number of forms have been described as species and subspecies, of which possibly one-third are entitled to stand. Some of those on the Asian mainland, as the Pekin Sika Deer, are much larger than the Japanese Sika, and also more strikingly colored. The latter species, shown in our northernmost corral, is about 33 inches in height, and of a dull and uninteresting smoky-brown color. Its antlers are quite large for a deer so small, and in the mating season males are sometimes dangerous. This species is very hardy, breeds persistently, requires no heat in winter, and very rarely sends a case to the hospital. [Illustration: AXIS DEER.] The Fallow Deer, (_Dama vulgaris_), is the type of a distinct group of deer which are distinguished by the possession of antlers widely palmated throughout the upper half of the beam. In some old Fallow bucks the antlers are quite moose-like, and give this small deer an imposing appearance far out of proportion to its actual size. The weight of a large buck in prime condition generally is between 180 and 200 pounds, and its shoulder height is between 36 and 40 inches. The largest antlers recorded by Mr. J. G. Millais, in his beautiful work on “The British Deer,” measured 29½ inches in length, 28½ inches spread, width of palmation 8 inches, and the number of points 14. The extinct Irish elk, with the most colossal antlers ever carried by a cervine animal, was a near relative of the two living species of Fallow Deer. Although a native of northern Africa and the north shore of the Mediterranean, the Fallow Deer was acclimatized in England and northern Europe so long ago that the exact date records of the event have disappeared, and the species is now at home in very many European forests and game preserves. The deer parks in England possess many fine herds, but they sometimes exhibit one unfortunate result of long breeding in a semi-domesticated state—departure from the original type. The typical Fallow Deer is in winter very dark brown, with light brown legs and under parts, and in summer light red with white spots—quite like the axis. From this standard, the variations run from pure white through the color of the wild type to jet black. The fine herd in the Zoological Park is the gift of Mr. William Rockefeller. Six of its original members came from the donor’s herd at Greenwich, Connecticut, and six were purchased from one of the imperial parks of Russia, by consent of the Czar, and represent the most hardy stock obtainable.
