Do Black Bears Eat Deer?


Black bears and whitetail deer are two of the most common wild animals in North America, found in many regions all over the continent. As the former are opportunistic omnivores and will eat meat when they get the chance, many people ask do black bears eat deer?

In today’s article we’ll answer the article’s primary question, and explore some of the nuances of the relationship between deer and black bears, including all sorts of information about the dietary preferences of black bears.

Do Black Bears Eat Deer Meat?

While it’s possible for a black beer to hunt and eat a full-grown deer, it’s quite rare. Black bears do like to eat meat when there is an opportunity to do so. Black bears may prey on fawns away from their mothers. And if a black bear finds a dead deer, it will certainly scavenge on the carrion. Black bears are unlikely, however, to attempt hunting a full-grown deer, as it may not be worth the energy.

Do Black Bears Hunt Deer?

It’s very rare for a black bear to successfully hunt and take down an adult deer. In some circumstances, a large black bear may target an injured adult that is away from the herd.

It’s much more likely for a black bear to hunt a fawn (baby deer) that is away from the protection of its mother.

A situation in which black bears may eat meat from a full-grown deer is if they find the animal already dead.

After all, black bears are opportunistic omnivores. As such, they’ll often act as scavengers.

Do Black Bears Eat White-Tailed Deer?

Unlike Kodiak or brown bears, it’s relatively rare for a black bear to eat a deer, but it can happen.

White-tailed deer are smaller than some other types of deer (such as elk), so if a black bear is going to eat a deer, it will probably be this one.

In most cases, a black bear consuming white-tailed deer meat occurs when they capture a fawn that is away from the herd.

Also, black bears will eat carrion. So, if they find an already dead white-tailed deer (say, one that was hit by a car), they will probably eat the meat.

What Animals Do Black Bears Eat?

Black bears are omnivores. This means they eat both vegetation and meat.

However, the majority of their diet consists of vegetation. This is especially true in late summer and the fall, as these times of year typically provide lots of nutritious nuts and berries.

When it comes to mammals, black bears tend to stick to smaller varieties. These predators also eat birds and fish.

Spring is the time of year when bears occasionally eat deer fawns. Depending on the region, they may also eat elk calves, caribou calves, and even moose calves in some cases.

If a black beer finds carrion (for example, an already dead deer), it will possibly feed on it.

Insects are a large part of the black bear diet. When it comes to vegetation, some of the foods black bears especially enjoy include blueberries, apples, black cherries, buffalo berries, elderberries, and strawberries.

Black bears also eat plenty of nuts, including acorns, beechnuts, and hazelnuts.

Black bears also eat insects. One common example is ants.

Other Bears that Hunt and Eat Deer

Both grizzly bears and polar bears are natural predators which will hunt and eat deer, but neither consumes as many as wolves do.

Grizzly Bears

Grizzly bears are much larger and more ferocious than black bears. A male grizzly bear may easily reach 800 pounds, and females may exceed 450 pounds.

The tallest grizzly bears may measure as many as eight feet when standing up on their hind legs.

Accordingly, these bears are much more likely than black bears to hunt full-grown deer. In fact, grizzly bears frequently take down and eat animals such as elk and even moose and bison.

In some regions, grizzly bears hunt large numbers of these large herbivores each spring.

While grizzly bears certainly hunt and eat more meat than black bears, they are omnivores.

They eat a large array of vegetation as well as meat, including grasses, horsetail, clover, dandelions, and more. Grizzly bears also enjoy and look for berries and nuts.

In the summer months, grizzly bears tend to increase the number of vegetation types they consume. They also prey on elk calves.

Grizzly bears are also well-known for eating fish that they catch from streams, lakes, and rivers.

Grizzly bears live in places such as Washington state, Idaho, Wyoming, Alaska, and Montana.

They are also found in British Columbia, a province of Canada. Experts believe there may also be a grizzly bear population in southern Colorado.

Polar Bears

If they can, polar bears prefer to stick with eating seals, as they’re an excellent source of fat.

However, as global warming continues to become even more of a problem, these bears are having to become even more resourceful. This means they are more often hunting large land mammals such as deer.

Of course, the polar bear is an extraordinarily large animal, many times larger than black bears and bigger even than the largest grizzly bears.

This makes these bears well-equipped to hunt deer. One kind of deer that polar bears have recently been witnessed hunting is the Reindeer or Caribou.

Polar bears are more limited in where they can live than other kinds of bears. They live in Arctic areas, and they need waters covered with ice in order to successfully hunt seals, which are the staple of their diet.

Polar bears are simply enormous, with males weighing as much as 1,500 pounds. They may be as tall as 10 feet when standing up on their hind legs.

Will Black Bears Eat Deer? Rarely.

As we’ve seen here, it’s rare for a black bear to attempt hunting a full-grown deer.

Let’s review the fundamental facts about bears and deer.

  • Adult deer are too big for black bears to prefer as prey.
  • Black bears sometimes eat baby deer (fawns).
  • Black bears will scavenge on already dead deer.
  • Grizzly bears frequently hunt deer.
  • Global warming is causing polar bears to hunt deer.
