Endangered Wolf Center
The Endangered Wolf Center is a non-profit wildlife facility in Eureka, Missouri, United States, near St. Louis that is dedicated to preserving and reintroducing to the wild critically endangered species of wolves. It is certified by the Association of Zoos and Aquariums (AZA). The Center was founded in 1971 by renowned naturalist Marlin Perkins and his wife Carol, who saw that wolves around the world were in danger of becoming extinct. Its mission is to preserve and protect Mexican wolves, red wolves, and other wild canid species, with purpose and passion, through carefully managed breeding, reintroduction and inspiring education programs. Animals born at the facility have been reintroduced to North Carolina (red wolves) and Arizona and New Mexico (Mexican wolves). The Center's research focuses on reproductive, behavioral and nutritional needs for the species housed there. The Endangered Wolf Center is a founding member of the AZA’s Mexican Wolf and Red Wolf Species Survival Plans. As of August 2016, the Center had six species of endangered canids: Mexican wolves, red wolves, maned wolves, African painted dogs, fennec foxes and swift foxes. It had more than 20 Mexican gray wolves, more than any other managed breeding facility. (Only 97 Mexican wolves were known to exist in the wild as of 2015.) The Center serves as the cornerstone of the U.S. Fish and Wildlife Service's program to preserve Mexican wolves and reintroduce them to the wild.
Wolf hunting
The grey wolf "(Canis lupus)" is the largest member of the canidae. Though once abundant over much of North America and Eurasia, the grey wolf inhabits a very small portion of its former range because of widespread destruction of its habitat; in some regions it is endangered or threatened. Considered as a whole, however, the grey wolf is regarded as of least concern for extinction according to the International Union for the Conservation of Nature and Natural Resources. Wolf weight and size can vary greatly worldwide, tending to increase proportionally with latitude as predicted by Bergmann's Rule. Wolves are usually hunted in heavy brush and are considered especially challenging to hunt, because of their elusive nature and sharp senses. Grey wolves are notoriously shy and difficult to kill, having been stated to be almost as hard to stalk as cougars, and being far more problematic to dispatch with poison, traps or hounds. However, wolves generally do not defend themselves as effectively as cougars or bears. Some wolves will evade capture for very long periods of time and display great cunning. One specimen nicknamed "Three Toes of Harding County" in South Dakota eluded its pursuers for 13 years before finally being caught. Another wolf nicknamed "Rags the digger" near Meeker, Colorado would deliberately ruin trap lines by digging up traps without tripping them. In sport hunting, wolves are usually taken in late autumn and early winter, when their pelts are of the highest quality and because the heavy snow makes it easier for the wolves to be tracked. Adult wolves are usually too fast to be overtaken by wolfhounds, but not for well conditioned horses, especially in thick snow. A shot wolf must be approached with caution, as some wolves will play possum. Accounts as to how wolves react to being trapped or cornered vary. John James Audubon wrote that young wolves typically show little resistance to being caught, whereas older, more experienced wolves will fight savagely.
