Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects.

The animal on the cover of LDAP System Administration is a mink (Mustela vison). Mink are found throughout the United States and Canada except in Arizona, the Arctic, and some offshore islands. A mink's fur is mostly brown with some white spots around the throat, chin, and chest. Its coat is thick, soft, and waterproof (thanks to guard hairs covered with an oily protective substance). Its body is streamlined and skinny with short legs and an elongated face. As part of its water-loving nature, a mink's toes are partially webbed. Body length varies but is usually around two feet. The tail comprises almost half of a mink's total length.

Females become fertile during the winter and give birth in April or May. A typical litter ranges between one and eight offspring. M. vison is a solitary species; males are particularly intolerant of each other. They mark their territories with a pungent, musky secretion from their oversized anal glands. They are especially active at night and are skilled swimmers and climbers. Mink dig burrows in banks of lakes and rivers, or they may occupy abandoned dens of other mammals, such as muskrats. Their tastes in food changes from season to season, but they tend to dine on small mammals such as mice, rabbits, and shrews, along with fish and duck.

The main threat to the mink's existence continues to be the fur industry. Most U.S. states and all of Canada have limited trapping seasons with strict quotas on catch size. These provisions help keep mink population densities constant. Mink have few natural enemies other than humans. Occasionally, they will be hunted by coyotes, bobcats, and other meat-eaters.
