Wolves are the largest members of the dog family and are classified as carnivores. They are also known as opportunistic hunters, meaning they will eat whatever is easiest to obtain. Their diet typically consists of large, hooved herbivores such as deer, elk, and moose, but they also prey on smaller animals such as beavers, hares, raccoons, rodents, birds, fish, and even garbage. The specific composition of a wolf's diet depends on its location, with wolves in North America primarily consuming wild large hoofed mammals, while those in Asia and Europe eat more medium-sized hoofed mammals and domestic species.

What You'll Learn
Wolf diet varies by location
Wolves are the largest members of the dog family and are classified as carnivores. They are also considered opportunistic hunters, meaning they feed on what is easiest to obtain, such as vulnerable individuals. This includes weak, sick, old, or young animals. Their diet varies depending on their location and the availability of prey.
In North America, the wolf's diet is dominated by large wild hoofed mammals (ungulates) and medium-sized mammals. Elk, moose, caribou, white-tailed deer, and mule deer are among the most important prey for wolves in this region. Wild horses used to be frequently consumed by North American wolves before their extirpation from the continent.
In Asia, wild species may not be readily available, so wolves are more reliant on domestic species. Across Eurasia, wolves prey mostly on moose, red deer, roe deer, and wild boar.
A study of wolves in the Alexander Archipelago and southeastern mainland of Alaska found that their diet consisted of about 65% ungulates, with the specific type of ungulate varying by location. On the mainland, wolves primarily preyed on moose and mountain goats, while on some of the islands, Sitka black-tailed deer were their main prey.
In northeastern Minnesota, white-tailed deer, moose, and beavers are the top menu items for wolves. A study by Barber-Meyer and Dr. L. David Mech found that as the moose population declined, the wolf population doubled, as they supplemented their diet with white-tailed deer.
The diet of wolves near human settlements can consist largely of garbage from dumps, as well as domestic animals. For example, Italian wolves' diets consist of 60-70% garbage, along with deer, boar, and small mammals.
Red wolves, a distinct species from coyotes, are smaller than gray wolves and have different dietary habits. They mostly dine on smaller animals and only rarely hunt ungulates, given their limited habitat. Raccoons, rabbits, mice, and other rodents constitute the majority of a red wolf’s diet. They also snack on non-meat foods like insects and berries.

Wolf diet varies by season
The wolf's diet varies depending on the season and the region. In general, wolves are carnivores that feed on large wild hooved mammals, known as ungulates, and smaller animals. Their diet also includes livestock, carrion, and garbage.
During the winter months, wolves tend to have more access to weak and undernourished prey, as they can easily navigate through deep snow and tundra. Their preferred prey during this season includes ungulates such as deer, caribou (reindeer), and moose. The winter diet of wolves in North America consists mostly of wild large hoofed mammals, while those in Asia and Europe consume more wild medium-sized hoofed mammals and domestic species.
In the spring and summer, wolves may include fish and beaver in their diet. Beavers are especially important for wolves in Northern Minnesota as a food source for their growing pups during these seasons.
The early summer is also a bountiful time for wolves due to the higher presence of younger prey animals. This is when wolves can take advantage of the seasonal availability of younger and weaker prey.
Additionally, the diet of wolves can vary depending on their location. For example, wolves in Alaska have been found to prey on moose, mountain goats, and Sitka black-tailed deer, while wolves near Gustavus have a more varied diet that includes sea mammals, black bears, and salmon.

Wolves are opportunistic hunters
Wolves are large carnivores, and their main prey are large, hooved herbivores, or ungulates, such as moose, elk, deer, caribou, and bison. They are also known to prey on smaller animals such as beavers, hares, raccoons, rodents, and birds. Wolves are opportunistic hunters, and their flexible diet has allowed them to survive and thrive in various ecosystems across the Northern Hemisphere.
Wolves are highly adaptable and will take advantage of whatever food sources are available to them. For example, wolves in Minnesota have been found to supplement their diet with fish during the spring and summer months, when beaver populations may be lower. In areas where ungulates are scarce, wolves have been known to expand their dietary niche to include a variety of species, such as black bears, sea otters, and salmon.
The social hierarchy within a wolf pack also plays a role in their opportunistic hunting behaviour. The dominant breeding male and female typically feed first, with other pack members following in a specific order. This means that wolves will take advantage of whatever food sources are available to them, ensuring they get their share.
The success of wolves as a species can be attributed in part to their adaptability and opportunism when it comes to hunting and scavenging. They are able to survive in a range of ecosystems and can switch between prey species as needed. For example, a study in northeastern Minnesota found that as the moose population declined, wolves supplemented their diet with white-tailed deer. This adaptability allowed the wolf population to almost double during the study period.
In addition to hunting, wolves will also scavenge and eat carrion, garbage, and even domestic livestock and pets when necessary. This further highlights their opportunistic nature and ability to thrive in various environments.

Wolves eat a mix of plants and meat
Wolves are the largest members of the dog family and are classified as carnivores. They are also opportunistic hunters, which means they will eat what is easiest to find. This includes weak, sick, old, or young animals. They are also scavengers and will eat carrion and garbage.
The wolf's diet is varied and includes a mix of plants and meat. While their primary prey is ungulates (hoofed mammals), they also eat smaller animals such as beavers, hares, raccoons, rodents, birds, fish, and even berries and insects. In some cases, wolves have been known to prey on domestic livestock and pets, which has earned them a bad reputation among humans.
The specific composition of a wolf's diet depends on its location. For example, in North America, the wolf's diet is dominated by wild large hoofed mammals (such as elk, moose, caribou, and deer) and medium-sized mammals. In Asia and Europe, their diet consists mostly of wild medium-sized hoofed mammals and domestic species.
The social hierarchy within a wolf pack also dictates the order and quantity of food eaten by each member. The dominant, breeding male and female feed first, and their offspring may have to beg for access to food.
The dietary flexibility of wolves is one of the reasons for their success as a species. They are able to survive and thrive in a range of ecosystems across the Northern Hemisphere, from grasslands to the vast, dry Arctic tundra.

Wolves eat a lot of food in one sitting
Wolves are the largest members of the dog family and are classified as carnivores. They are slender and powerfully built, with long legs, a large head, strong jaws, and heavy teeth. These physical adaptations enable them to tackle large prey and travel long distances in search of food.
Being opportunistic hunters, wolves primarily feed on large, hooved herbivores called ungulates, such as deer, elk, moose, and caribou. However, they have adapted to a varied diet and will prey on smaller animals, including beavers, hares, marmots, rodents, birds, and even fish. A single wolf can consume up to 10 kg (22 lb) of meat in one sitting, which is equivalent to gorging on several pack animals at once. This ability to gorge is essential, as wolves often go through feast-or-famine cycles, enduring several days without food and then indulging in a large meal when they make a kill.
The amount of food a wolf can eat in one sitting is remarkable and is directly related to their stomach capacity. Their stomachs can accommodate a massive amount of food, allowing them to gorge when necessary. This ability to consume large quantities of food at once is a survival mechanism that has helped wolves thrive in various ecosystems.
The social hierarchy within a wolf pack also influences how much food each member consumes. The dominant breeding male and female feed first, and their access to food is prioritized. This dynamic ensures that the strongest and most vital members of the pack have the energy to lead the group and reproduce.
In addition to their impressive consumption capacity, wolves are also known for their dietary flexibility. While they prefer meat, they will scavenge and eat carrion, garbage, and even plants when necessary. This adaptability has contributed to their success as a species and their ability to survive in diverse environments.
