Are Black Bears Omnivores? (7 Types of Food They Eat)


The different feeding habits of black bears may make you wonder whether they are omnivores.

Black bears are omnivores since their diet consists of berries, insects, and small mammals. In fact, omnivores feed on both plants and animals. 

Including insects and berries in the diet directly means that the black bear is omnivorous.

Black bears usually feed on plants or animals, depending on the season. In this article, I will discuss the plants and mammals that black bears feed on.

Seven Types of Food Black Bears Eat

There are 7 main types of foods that black bears eat. These foods include:

  1. Plants
  2. Mammals
  3. Insects
  4. Fruits and berries
  5. Fish
  6. Birds and eggs
  7. Amphibians and reptiles

Plants

More than 80% of the black bears’ diet consists of greens. The most common types of vegetation that black bears feed on are:

  • Lillies
  • Fireweed
  • Alfalfa
  • Dandelions
  • Clover

Unlike most other animals, black bears have a longer digestive tract. This digestive tract plays a huge role in absorbing nutrients from plants.

Black bears only feed on the above plants when they are tender and nutritious.

Black bears love to feed on plants that have broad leaves. Broad leaves usually mean that the plant is soft. Digestion becomes easy when the plant is smooth, where the clovers and dandelions come in.

The softness of the dandelions and clovers always attracts black bears. Some roots and flowers also attract this kind of bear at some points.

Despite having the urge to feed on roots, black bears do not like digging for roots. Lack of interest in searching for roots takes them to the available flowers.

Mammals

Being carnivorous as well, black bears usually feed on different animals. The most common animals that black bears feed on are:

  • Deer
  • Young caribou
  • Moose
  • Elk
  • Beavers
  • Bobcats
  • Wolves
  • Voles
  • Red foxes
  • Mice
  • Ground squirrels
  • Coyotes

Besides the small animals above, black bears also feed on larger ones. This kind of bear has the power to take down even huge prey and convert them to food. 

Larger animals usually have more protein than smaller ones. The search for high protein makes the black bears go to the extent of hunting large animals.

In some cases, black bears usually wait for other animals to hunt down large animals and then fully take over.

Black bears also feed on leftovers of prey in other scenarios. Occasionally, animals may die from natural disasters such as long winters. The black bear takes the opportunity of long winter to feed on weakened animals.

Did you know?

The most favorite type of nut for black bears is the hazelnut. Several black bears may take on very long distances just to get a grasp of some hazelnuts.

The black bear doesn’t have a problem with nuts on trees. Most black bears can climb onto trees. The climbing capability is a plus when it comes to searching for nuts.

Reptiles and Amphibians

Some black bears are more courageous, meaning they would go further to even feed on dangerous reptiles. The alligator is the most common reptile that black bears attack. The black bears mostly feed on young alligators and their eggs.

What is the Most Favorite Food for Black Bears

Besides eating different foods, black bears have a favorite type of food. These bears mostly love feeding on green foods. Black bears love to feed on plants more than any other type of food.

Plants are readily available and quite easy to get, unlike hunting animals. For that reason, greens take the crown as black bears’ favorite food.
