The Grey Wolf: Keeping the Balance of Predator and Prey.

Grey Wolf imageLittle Red Riding Hood and The Three Little Pigs would be the first to say that wolves are bloodthirsty and evil, yet on the other hand, the now deceased Canadian author and environmentalist Farley Mowat would have said the complete opposite. Who do we believe, a cute little girl in a red hood, three pigs in overalls, or Farley Mowat famed author of the book, Never Cry Wolf

Without question, the howl of North America’s Grey Wolf is hair-raising. It leaves many people trembling and wondering if there really are werewolves. Howling is a very important part of the wolves’ communication.  Howling asserts their territory to other wolf packs, or to make themselves known to their own pack from afar. Their howls can be heard from 10km away. 

Grey wolves vary in colour from white, grey or black; however, as their name suggests, they are typically grey in colour.  Grey Wolves are about the size of a German Shepard with longer legs and a bushier tail. Their average weight ranges from about 20 to 75 kilograms. 

Wolves are pack animals. Wolf packs can be as few as two, but typically the pack consists of six to eight members. There is a strict hierarchy, which is led by the alpha male.  The lower ranked wolves know their place; therefore, there is very little fighting within the pack. Typically, the alpha male and female are the only ones that breed. The alpha male and the rest of the pack protect the nursing mother and her pups. They feed them by regurgitation.

Wolves go after large prey such as deer and moose. They can eat approximately 9 kilograms of meat in one sitting and can go without eating for about a week. Unfortunately, they can prey on domestic livestock, causing conflict with ranchers and farmers. This conflict has caused countless wolves to be shot, trapped or poisoned. Wolves’ tendency to prey on livestock is part of the reason why they have been vilified. Wolves almost never attack humans, contrary to many stories and fairy tales. 

Did you know, wolves have been called defenders of the wild? Despite the horror fairy tales wolves are an important part of our eco system. If their numbers dramatically drop (such as from over hunting), the natural order can become greatly disturbed. Large animals like the elk become over populated (Yellowstone’s northern valleys depict a great example). The elk begin to destroy their own habitat, which causes a negative chain reaction. The stream edges become trampled, trees and shrubs get stripped, causing erosion and lack of valuable shade. There is a loss of habitat for fish, reptiles, birds, water insects and etc. With no wolves, animals such as badgers, foxes, and weasels, lose the opportunity to supplement their diets by feeding on left over carcasses (after the wolves have eaten their fill). Struggling raptors benefit by being able to feed on the leftovers, too. Wolves help to keep the balance of predator and prey, and like all wild animals they have a place in nature. Interesting note: Once the wolf population was built back up in Yellowstone, the ecosystem became vibrant again.

You might be wondering now if we have wolves in the Wilden neighbourhood. To date no wolf sightings in Wilden are known of or have been reported. There have been been sightings of wolves in the Okanagan by hunters, more so on the Westside and in Peachland.

All in all wolves are an important part of the natural order. There are many fascinating studies about them. Farley Mowat’s book, Never Cry Wolf is a great place to start. Sorry Little Red Riding Hood and the Three Little Pigs!
