What wolves eat

As carnivores, wolves will eat anything from a mouse to a moose including grasshoppers, birds and frogs. Although wild wolves will occasionally eat berries, their bodies require meat to survive.

As Jack London wrote in White Fang, a story about a wolf-dog hybrid, “The aim of life was meat. Life itself was meat.”

Most wolves obtain their meat from ungulates such as deer, elk, moose, bison and muskoxen. While it’s dangerous hunting large animals with horns and hooves, the huge food reward is worth the effort and risk of injury or even death. On the other hand, it takes a lot of mice to fill a wolf’s belly and the energy expended is often greater than the calories gained.

While most wolves depend on ungulates for their sustenance, some eat a lot of fish. This has been recorded throughout the world and often involves fish travelling upstream to spawn.

But some wolves rely heavily on fish and marine-related animals year-round. In fact, wolves on some British Columbia coastal islands primarily eat salmon, seals and shellfish, as well as mink and Canada goose eggs. They will even move rocks at low tide to eat tiny molluscs called chitons. Wolves on outer islands may seldom – if ever – see a deer.

Wolves aren’t picky about their food. They may cache some meat and dig it up for dinner later, as well as scavenge prey that has died of natural causes or been killed by other animals.

They can easily become used to the easy pickings found at unsecured human garbage dumps and will raid campsites or break into tents and kayak holds to check out human food. Although they probably won’t eat much of the food they find this way, they will bite into whatever they can access to check it out.

At times, wolves also kill and eat livestock and pets, which is the major source of their conflict with humans.

Will wolves howl at the super blood wolf moon?

From ancient times, Indigenous peoples in North America called the first full moon after the winter solstice the Wolf Moon. This was often the coldest, darkest month of the year, when hungry wolves could be heard howling outside villages.

The sky will provide a backdrop for some extra drama when 2019’s Wolf Moon takes place the evening of January 20 – 21. On that night the full moon will pass its closest to earth making it appear larger and brighter than normal. That adds the super to Wolf Moon.

And, depending where you are, at some point that night the earth will move between the sun and the super Wolf Moon creating a total eclipse. The earth’s shadow makes the moon appear red, hence the term blood.

A super blood wolf moon is relatively rare, occurring approximately every three years. But how do wolves respond to this lunar event?

Wolves howl, hunt and travel at any time but are most active around dawn and dusk, as well as throughout the night. And whether they’re sitting, standing or lying down, they lift their snouts to howl. But, rather than focusing on the moon, some believe they’re simply taking advantage of the extra light it provides.

“I know from sleeping near the Sawtooth Pack for eleven years that wolves do howl more during a full moon,” Jeremy Heft writes in the summer 2009 Sawtooth Legacy Quarterly. A wildlife biologist, Heft’s worked at the Wolf Education and Research Center in Winchester, Idaho, since 1998. “They tend to be more active then because it’s easier to see prey and hunt.”

In the 1970s, wolf researcher Paul Paquet observed unusual behaviour in a pack during a solar eclipse. The wolves were actively wandering around an estuary on the BC coast when the moon passed between the earth and the sun. As the light faded, the wolves gathered together along the shoreline and gazed in the direction the bright sun had been. They only resumed their normal routine when the sun began to reappear.

So it’s hard to say how wolves will react to a super blood wolf moon. My guess is they may howl earlier in the night when the moon is brightest but stop to gaze upwards during the dimming of light and change of colour during the blood phase.

Wolf scat and butterflies

Wolves have cast-iron digestive systems capable of handling fragments of bone and shell, animal fur and even the intact nails from a seal.

When it comes to food, wolves are opportunistic. They’ll eat berries and have been known to nibble on human food and garbage. String and remnants of clothes have also been found in the scat of camp robbers.

Wolf scat looks similar to a piece of cord and usually tapers to a point on the end. An adult wolf’s scat is usually between 25 to 38 millimetres (one to 1.5 inches) in diameter. If it’s runny, the wolf may have recently eaten some bloody meat.

Una Ledrew and Dave Ratcliffe were startled when they observed chunks of rope in wolf scat near their home. “They were chewing on and swallowing ropes of all kinds, plastic rope, big thick rope we use to tie up the skiff,” Ledrew said.

My guess is the wolves were after the salt left behind by human hands but some of the rope had been out in the open for ages. Wolf experts I spoke to were baffled as to why wolves would consume rope.

Wolf scat is more than just part of a wolf’s elimination process; it’s also an important part of lupine communication. Scat is one way wolves’ mark their territory and is often found in conspicuous locations such as trail intersections.

These visual and olfactory markers serve as a signal to warn other wolf packs out of their territory or to let family members know they’ve passed that way. Wolf scat is also part of nature’s recycling program, enriching the soil wherever it’s deposited.

But the biggest surprise about wolf scat is butterflies. They aren’t in it, they’re on it. Apparently, butterflies love wolf scat due to the high concentration of nutrients. In fact, numerous researchers told me, “If you’re looking for wolves, look for butterflies.”

Of wolves and moose

A few weeks ago, a friend urged me to check Return of the Wolf on amazon.ca “Right now!”

“Oops,” I thought. “Some info in the product details must be wrong. And then a sick foreboding – maybe someone had posted a dreadful review?

I quickly googled the page and was baffled to see orange text proclaiming #1 in Bestseller in Wildlife under the title. It took few minutes for the significance to sink in.

I let out a little shriek and immediately emailed the link to friends and family. At the time I wasn’t sure if ratings were based on hits or actual purchases. I now know it’s the latter. And that ratings are reconfigured hourly.

A little later in the day I googled amazon.ca and saw that Wolf had slipped to #2. Okay, so I’d had my fifteen minutes of fame. And to keep things in perspective, a moose calendar was #4.

Wolves and moose have a long relationship as predator and prey. Researchers have witnessed single wolves take down an adult moose so it can be done.

But most wolves tackle the 360 to 450 kg (800 – 1,000 pound) ungulates as part of a pack. Even then, it’s estimated that they’re only successful one to nine percent of the time.

It’s dangerous too as the moose may kick or stomp a wolf with its sharp hooves, batter it with its heavy antlers or use them to flip the canid end over end.

So, when it comes to a physical confrontation, a healthy adult moose is more than a capable match for a lone wolf or even a pack.

But how do wolves and moose fare when it comes to human emotions? I’d never thought about it until I saw the animals so closely linked on the amazon.ca bestseller list.

For a couple of weeks I randomly checked Return of the Wolf’s status on amazon. The book slipped down to #8 and then ping-ponged to #157 and back up to #22 with numerous stops in between. And through it all, the moose calendar held steady at #4.
