In Wolves , many of the world's leading wolf experts provide state-of-the-art coverage of just about everything you could want to know about these fascinating creatures. Individual chapters cover wolf social ecology, behavior, communication, feeding habits and hunting techniques, population dynamics, physiology and pathology, molecular genetics, evolution and taxonomy, interactions with nonhuman animals such as bears and coyotes, reintroduction, interactions with humans, and conservation and recovery efforts.
The book discusses both gray and red wolves in detail and includes information about wolves around the world, from the United States and Canada to Italy, Romania, Saudi Arabia, Israel, India, and Mongolia.
How Wolves Hunt
Wolves is also extensively illustrated with black and white photos, line drawings, maps, and fifty color plates. Unrivalled in scope and comprehensiveness, Wolves will become the definitive resource on these extraordinary animals for scientists and amateurs alike. It is designed for a wide readership, and certainly the language and style will appeal to both scientists and lucophiles alike. This is an excellent summary of current knowledge and will remain the standard reference work for a long time to come.

Wolves need an average of three to ten pounds of meat each day. Hunting is not always successful, so their bodies are designed to feast eat a lot or famine eat nothing.
Wolves can eat as much as 22 pounds of meat at a time and then may not eat again for many days. Wolves require from one to three quarts of water per day, depending on the size of the animal, the climate, and the moisture content of the prey. When hunting in winter the wolf will conserve energy when ever possible, by following the same trail as the prey animal, staying upwind, and staying out of sight of the prey as long as possible. When it is time to strike the wolf will start wagging their tails with excitement.
Some times when young pups are with the hunt they may dash after the prey in the excitement and spoil the hunt. Wolves are primarily nocturnal animals that avoid the heat of day. They generally commence hunting at dusk. Wolves detect prey by three primary means, sent most common , tracking, and chance encounters. After prey is detected, wolves may split up to search through brush, travel on ridge tops searching for the prey below, or test herds looking for signs of weakness.
Hunting & Feeding Behavior | International Wolf Center
It has long been recognized that wolves often take advantage of wear members of the herd. In , Captain Clark of the famed Lewis and Clark expedition wrote that prairie wolves followed buffalo and fed "on those that are killed by accident or those that are too pore or fat to keep up with the ganges.
Later researchers reinforced the image of the wolf as a predator of the very young, the very old, the weak, of the diseased.
Aldolph Murie, in the Wolves of Mount McKinley, wrote: "Many bands seem to be chased, given a trial, and if no advantage is gained or weak animals discovered, the wolves travel on to chase other bands until an advantage can be seized. Lois Crisler notes in Arctic wild, "In all our time in the arctic, the only healthy caribou we saw or found killed were fawns with big herds. Fuller and L. Kieth found that "wolves killed disproportionately more young, old and probably debilitated moose Ales alces , as well as more female calves. Although it does not prey only on the weak and the ill, the wolf is opportunistic, and it is inevitably the disadvantaged that are the easiest to catch.

Weakened animals may show thier condition to predators through body stance, uncoordinated movements, the smell of wounds or infection, or some other tangible signal. The reading and evaluation of these signals comprises what Barry Lopez has poetically termed "the conversation of death.
Once a weak individual is selected by a pack, wolves will usually travel upwind.

By traveling upwind, the sent of any prey will be carried to them. They will follow the air currents directly to the game. Or, they may follow the sent trail left by a game animal's foot tracks and body odors. Just before the chase wolves prefer to make there final approach downwind so there body sent is not carried to the prey species, alerting it to their presence.
On the Hunt
Prey that runs is usually chased. Prey that stands its ground may be able to bluff off its pursuers. Moose and Elk often take to deep water or swift rivers and await departure of the pursuing wolves, But more often than not the wolves wait.
While the majority of the pack rests, one or two members test the prey for signs of fatigue. Usually the chases are short, but L. David Mech has stated that "One wolf I know of chased a deer for 13 miles. David Gray described one such encounter in Canada's high Arctic in the musk-oxen of Polar Bear Pass :"the wolves approached to within a hundred meters of the herd Contrary to popular belief, most prey chased by wolves actually gets away. In one study, only three percent of the moose that were tested ended up being killed.
The percentage of prey that is killed is called the "predation efficiency," and in spite the wolf's prowess as a hunter, the majority of his prey escapes.
