The mother and other pack members participate in establishing and digging a den, where the pups will be born.
The den area is located away from any disturbances, such as people or roads. A den can be dug out of the ground, in a hollow log, rock crevice, or even an abandoned beaver lodge! The entire pack is focused on provisioning the pregnant female during this time.
Dad may bring the Mom food at this time if she does not want to hunt herself. Early Spring The breeding pair of wolves has a litter of pups that consists of four to six little ones on average. The family lives in a den at the time the pups are born. Alphas exclude non-pack members from their territory, and try to kill trespassers.
Mature, subordinate pack members are sometimes less hostile to outside wolves — they are potential mates. Being an alpha wolf requires aggression, control, and leadership. Perhaps not surprisingly, alpha wolves typically possess higher levels of stress hormones than do subordinate wolves, who may not eat as much, but have, apparently, far less stress.
Pack members are usually, but not always friendly and cooperative. Wolves from other packs are usually, but not always enemies. Accurately interpreting and judging these communications requires intelligence. Communication and intelligence are needed to know who my friends and enemies are, where they are, and what may be their intentions.
These may be the reasons that most social animals, including humans, are intelligent and communicative. Like humans, wolves communicate with voices.
Pack mates often separate temporarily. When they want to rejoin they often howl. There is so much more to wolf communication. Scientists recognize at least ten different categories of sound e. Each is believed to communicate a different, context-dependent message. Wolves also have an elaborate body language. As subtle as body language can be, even scientists recognize communication to be taking place by the positions of about fifteen different body parts e.
Each body part can hold one of several positions e. There could easily be hundreds to thousands of different messages communicated by different combinations of these body positions and vocal noises.
Scientists apprehend or misapprehend just a fraction of what wolves are able to communicate to each other. Wolves also communicate with scent. The most distinctive use of scent entails territorial scent marking. Elusiveness makes wolves mysterious. This is true and fine. However, true love cannot survive mystery due to ignorance. Mature love requires knowledge.
In some basic ways the life of a wolf is very ordinary, even mundane, and its comprehension is fully within our grasp if we just focus. The life of a wolf is largely occupied with walking. Wolves are tremendous walkers. Day after day, wolves commonly walk for eight hours a day, averaging five miles per hour. They commonly travel thirty miles a day, and may walk 4, miles a year. Wolves living in packs walk for two basic reasons - to capture food and to defend their territories.
Isle Royale wolf territories average about 75 square miles. This is small compared to some wolf populations, where territories can be as large as square miles. To patrol and defend even a small territory, involves a never-ending amount of walking. Week after week, wolves cover the same trails.
It must seem very ordinary. The average North American human walks two to three miles per day. If you want to know more about the life of a wolf, spend more time just walking, and while walking, know that you are walking. What do wolves think about much while walking?
Wolves defend territories. About once a week, wolves patrol most of their territorial boundary. About every two to three hundred yards along the territorial boundary an alpha wolf will scent mark, that is, urinate or defecate in a conspicuous location. The odor from this mark is detectable, even to a human nose, a week or two after being deposited.
The mark communicates to potential trespassing wolves that this area is defended. Territorial defense is a matter of life and death.
Intruding wolves, if detected, are chased off or killed, if possible. Wolves are like humans for having such complex family relationships. When wolf puppies are first born, they're completely blind and deaf, and have little to no sense of smell. Their mother removes them from their fetal sacs, licks them clean and eats the placenta. Unable to move at more than a slow crawl or even to regulate their own body temperature, the pups need near-constant attention from their mother.
Litters normally contain between 4 and 6 members, but female wolves can give birth to up to 13 pups. Baby wolves grow rapidly, and gain between 2. When they reach between 11 and 15 days old, their eyes will open and they'll begin to see, although their eyesight is quite poor at first. Around this age, they'll also start to become more mobile and more vocal. A necropsy, or … Continued.
