The Maya Indians of the Peninsula of Yucatan have a legend that the black-headed vulture (_Catharista atrata_) in old age changes into an armadillo. The tale runs, that when a vulture becomes very, very old it notifies its companions that the time has come and alights before a hole in the ground that resembles the den of an armadillo. The other vultures bring food and the old one remains there for a long time. Its wings disappear, the feathers are lost, and when the change is complete the newly created armadillo enters the hole and begins its new life. If skepticism is expressed as to this metamorphosis, the Indians point out as proof of the legend the similarity between the appearance of the bald pate of the vulture and that of the armadillo. [Illustration: AMERICAN MINK TRACKS, SHOWING VARIOUS ARRANGEMENTS AND TAIL MARKS The typical track of a mink is as in the bottom set at the left, which also illustrates the tail mark. Twelve to twenty-four inches are usually cleared at each bound. This illustration is greatly reduced from natural size (see opposite page and pages 555 and 575).] =THE RING-TAILED CAT= (=Bassariscus astutus= and its relatives) (_For illustration, see page 562_) The mild climate and the proximity of the Southwestern States to Mexico and the tropics brings within our borders numerous strange types of wild life. Of these the ring-tailed cat is one of the most strikingly marked and interesting. In the United States it is known by several other names, including “civet cat,” “coon cat,” and “band-tailed cat.” In Mexico it still bears the old Aztec name cacomixtle, except in Lower California, where it is the “babisuri.” It is about the size of a large cat but with proportionately longer and slenderer body, shorter legs, and longer tail. The alternating bands of black and white on the tail proclaim its relationship, not to the cat, to which it has no kinship, but to the raccoon, which has a tail similarly marked. Few mammals possess such a beautifully formed head and face, and its large, mild eyes give it a vivid expression of intelligence. The ring-tailed cat occupies areas under such differing climates as to produce geographic races, but none of them vary strikingly from the typical animal here illustrated. They range from Oregon, Nevada, southern Utah, Colorado, and Texas south to Costa Rica. In Mexico they occur from near sealevel up to an altitude of about 10,000 feet. While chiefly rock-inhabiting species, they sometimes live in the forests and as a rule make their dens in caves and deep crevices, but sometimes in hollow trees or about houses. Their young, from three to four in number, are born in May or June.
