Identical to another wild animal, a grey wolf’s food regimen is dependent upon the place it lives on the continent, Yellowstone Wolf Venture technician Taylor Rabe tells Out of doors Life. Wolves reside in a spectrum of habitats. They reside within the woods of the Higher Midwest and the West’s peaks and valleys, and even the Alaskan tundra. They’ve developed in all these locations to feed on what’s available. That availability adjustments relying on the area’s latitude and longitude. Generally, these ample meals sources are giant herbivores.
Wolves within the West
In Yellowstone Nationwide Park and across the West, wolves have entry to ample wild ungulates like elk, deer, and pronghorn, Rabe says. Within the Pacific Northwest, they feed on moose along with elk and deer. In addition they have entry to bison in Yellowstone and another scattered components of the area.
“In Yellowstone Nationwide Park, about 80 p.c of our wolves’ food regimen is elk,” Rabe says. “About 15 to twenty p.c of their food regimen is bison. Wolves are opportunistic, [which means] they’ll take one thing if the chance presents itself. We see them forage on small rodents (mice, floor squirrels, rabbits), generally fish, beavers, and the occasional pronghorn or deer.”
Yellowstone’s elk quantity between 10,000 and 20,000 in the summertime. The wintering inhabitants is decrease, with round 4,000 elk.

Higher Midwest Wolves
Grey wolves are additionally ample within the Higher Midwest, particularly in northern Minnesota, northern Wisconsin, and Michigan’s Higher Peninsula. These wolves rely largely on whitetail deer, beavers, and moose (three broadly prevalent prey species) for meals.
Even inside this single area, a wolf’s food regimen varies, Rabe says. Wolves would possibly eat fish and even blueberries in Voyageurs Nationwide Park, in the event that they’re hungry sufficient. Moose comprise most of their food regimen in locations like Isle Royale Nationwide Park in Michigan. In sure components of the area, they eat so many beavers that the hydrology of the entire ecosystem adjustments, one examine reveals. This flexibility to eat regardless of the panorama gives is essential to wolf survival and inhabitants development. With out this adaptability, they wouldn’t be capable of roam and undertake new territories as their numbers proceed to extend.
Like wolves within the Mountain West, additionally they prey on livestock. Wolves had been confirmed to have killed 28 cattle, 10 chickens, and 5 sheep in Wisconsin in 2022, in keeping with the state’s annual livestock depredation report. And as a special report from the U.S. Division of Agriculture factors out, wolves are chargeable for depredations on about 1 to 2 p.c of ranches within the Higher Midwestern wolf vary yearly.

In the summertime months, most of their prey may be very sturdy and wholesome, so wolves are primarily feeding on neonates—new child elk and bison calves, and generally even pronghorn calves.

After they get determined, they may flip to different meals sources and scavenge previous kill websites for a meal.
A wolf pack’s searching model allows it to take down all these giant prey sources, Rabe says. Wolves have developed to work collectively to take down an animal 10 to twenty occasions their measurement.
“Completely different pack sizes can be extra environment friendly at sure sorts of prey,” Yellowstone Wolf Venture analysis affiliate Kira Cassidy instructed OL for an article on how wolves hunt. “A pack that desires to hunt bison has to have 9 to 13 wolves. A cool examine by Dan MacNulty discovered that, when you have lower than 9 wolves, the possibilities of efficiently searching a bison are extraordinarily low. Greater than 13 helps out a bit, however now we have much less and fewer information as packs get greater.”
