„Nordamerikanisches Katzenfrett“ – Versionsunterschied

Systematik

The Ringtail (Bassariscus astutus) is a mammal of the raccoon family (thus not actually a cat), native to arid regions of North America. It is also known as the Ringtail cat, Ring-tailed cat or Miner's cat, and is also sometimes mistakenly called a "civet cat" (after similar, though unrelated, cat-like omnivores of Asia and Africa). The Ringtail is sometimes called a cacomistle, though this term seems to be more often used to refer to Bassariscus sumichrasti.

Physical description

The Ringtail is buff to dark brown in color with white underparts and a flashy black and white striped tail that has 14-16 white and black stripes, which is longer than the rest of its body. The claws are semi-retractable . The eyes are large and purple, each surrounded by a patch of light fur. It is smaller than a housecat, measuring 30–42 cm long with a tail of 31–44 cm and weighing 0.8–1.5 kg. Ringtails have occasionally been hunted for their pelts, but the fur is not especially valuable.

Range and habitat

The Ringtail is found in California, Colorado, Oklahoma, Oregon, Arizona, New Mexico, Nevada, Texas, Utah and throughout northern and central Mexico. Its distribution overlaps that of B. sumichrasti in the Mexican states of Guerrero, Oaxaca and Veracruz. It is found in rocky, desert as its habitat, where it nests in the hollows of trees or abandoned wooden structures. The ringtail is the state mammal of Arizona. It is also found in the Great Basin Desert. The Great Basin desert covers most of Nevada and over half of Utah, as well as parts of California, Idaho, and Oregon.

Agility

The ankle joint is flexible and able to rotate over 180 degrees, a trait helping make it an agile climber. Their considerable tail provides balance for negotiating narrow ledges and limbs, even allowing them to reverse directions by performing a cartwheel. Ringtails also can ascend narrow passages by stemming (pressing all feet on one wall and their back against the other or pressing both right feet on one wall and both left feet on the other), and wider cracks or openings by ricocheting between the walls.

Habits

Ringtail in Phoenix, Arizona

It is nocturnal, solitary, timid, and rarely seen. It is omnivorous, eating fruits, berries, insects, lizards, small rodents, and birds. Owls, foxes, coyotes, raccoons and bobcats will prey upon ringtails. These small omnivores produce a variety of sounds, including clicks and chatters reminiscent of raccoons. A typical call is a very loud, plaintive bark. As adults, these mammals lead solitary lives, generally coming together only to mate.

Reproduction

Ringtails mate in the spring. The gestation period is 45–50 days, during which the male will procure food for the female. There will be 2-4 cubs in a litter. The cubs open their eyes after a month, and will hunt for themselves after four months. They reach sexual maturity at ten months. The ringtail's lifespan in the wild is about seven years.

Domestication

Ringtail in Phoenix, Arizona

The ringtail is said to be easily tamed, and can make an affectionate pet and effective mouser. Miners and settlers once kept pet ringtails to keep their cabins free of vermin; hence, the common name of "miner's cat" (though in fact the ringtail is no more cat than it is civet). Often a hole was cut in a small box and placed near a heat source (perhaps a stove) as a dark, warm place for the animal to sleep during the day, coming out after dark to rid the cabin of mice.
