What do beavers like to eat

Beavers are amazing creatures that are primarily found in North America. These rodents are famous for building lodges and dams in marine areas. But have you ever wondered why they are always into trees?

Well, they are into trees not only for their food but also for construction purposes.

Beavers love to eat a platter, with a variety that helps them get food throughout the year.

Below are a few of the food varieties that they love:

Inner bark

The soft inner bark of woody plants are beaver’s primary food source, particularly during the cold period between fall and spring. They prefer alder, aspen, birch, cottonwood, and willow bark among all the trees.


You will also see these rodents consume soft dead twigs whenever required.

Ferns and shrubs

You can also expect them to consume these during summer.


Most of the nutrients the beavers get are from the bark of the trees.

Aquatic plants

Though these animals do not like fish, you can feed them some aquatic plants. The most favorite ones are lilies and cattails.

Crops and Grass

These rodents also indulge in crop stems and leaves, especially beans and corn, which is a headache if you are growing around them.

Along with woody plants and trees, beavers also include some of the below soft vegetation:

  • apples
  • water lilies
  • grasses
  • clover
  • spatterdock
  • giant ragweed
  • duck potatoes
  • watercress
  • cattails

Occasionally, you can also feed them mushrooms too. However, fencing could be an option if you are someone staying close to beavers and concerned about your property.

If you are worried about beavers eating your plants and trees, try planting some trees they do not like. This will work as a natural fence, and you will not have to worry further.

What do beavers not eat

By reading the above section, you know that beavers are vegetarians and do not prefer to eat fish and meat. However, they are pretty picky and do not consume all plants. You know their likes now, but let’s see their dislikes as well.

Tree parts

Beavers are picky; in most cases, beavers will not eat the trees they cut. Precisely, they prefer only some parts of the tree, like the soft inner bark of the cambium.

Deciduous tree

Beavers are known to like deciduous trees. However, do you know they will never eat oak and alder trees? These trees are only used for their construction purpose.

Likewise, some of the trees that they don’t prefer are as below:

  • Ninebark bush
  • Osoberry trees
  • Twinberry trees
  • Cascara trees
  • Elderberry trees


Beavers are not great fans of berry plants. Try making them chew a few berries down if you ever meet one.


Remember when you have nothing to eat, and your go-to is bread and butter? For beavers’ conifers like hemlocks, fir, pine, and sitka, spruce is the last thing they would choose to eat.

Meat and fish

There’s no question of them eating meat and fish since they are hard-core herbivores. But if you have seen it in a TV show or cartoon, it isn’t real.

Lastly, beavers aren’t beggars. They will never eat your leftovers.

Digging from the trash can is never their style. So, if you ever get to feed a beaver, never give them leftovers. Now you know what do beavers eat and what not.

How do beavers survive

These rodents are mainly semiaquatic and nocturnal and are known for their building capabilities. They adapt smoothly to live on both water and land.

But how do they survive, and what do beavers eat under such circumstances? Let’s find out in the below explanation:


The broad, flattened tail of the beaver helps it in many ways, including communication. Like you have heaters during the cold, their tail helps them stay warm as it stores the fat there. They also use it as an alert by slapping their tails to startle any possible predators.

Heat Conservation

The beavers have an underfur fat layer that keeps them warm. They release castoreum oil, a water-repellent oil that helps to keep them underwater during the winter.


What do you think about how beavers eat their food? The beavers are well-known for the big buckteeth that help them get food and build shelter. Also, do you know that beaver’s teeth rapidly grow, but the gnawing makes them filed?

Underwater food access

How do you think that beavers get access to aquatic plants? Among all the other adaptations, beavers can stay underwater, which helps in their survival.

The clear eyelids protect its eyes to make them able to see underwater.

Do you know the best part? These rodents can close their ears and nostrils to keep the water out.

Their huge liver and lungs help them to store oxidized blood and conserve oxygen. This allows them to stay underwater for about 15 minutes. Don’t you envy them?

Additional adaptations

Some of the additional qualities that beavers have is the amazing ability to smell. This helps them to detect predators along with finding food.

Beaver types and their food habits

There are mainly two types of beavers you will ever see: the North American and the Eurasian. In the below points, you can figure out what beavers eat as per the type.

North American beavers

The North American beaver weighs about 16-30 kg on average. They are America’s largest rodent and they can even grow anything between 600-900 cm.

You can identify the North American beaver with its furry coat with a yellow-brownish and black hue. These beavers also have long incisors, which are dark orange and keep growing throughout their life.

One of the easiest ways to differentiate these beavers is their long flat black tail. Their tail helps them to balance themselves and use it as an alert.

The North American beavers are herbivorous. Their diet consists of woody stems, leaves, and aquatic plants. The favorite delicacies of these beavers are willow, birch, aspen trees, alder, maple, and poplar.

The Eurasian beaver

These beavers are also known as the European beaver. If you are from Great Britain or Europe, you must be familiar with these beavers. They were found huge in number earlier and mainly hunted for their castoreum and fur.

The Eurasian beavers weigh about 13-35kgs and grow between 73 and 135 cm. These beavers can be identified by their two layers of fur. If you look precisely, the undercoat is grey, and the outer part has long red-brown furs—their diet changes with the season.

During winter, they consume more willow, aspen, birch trees, and some woody plants. But they prefer shoots, twigs, leaves, roots, aquatic plants, and buds during summer. These creatures would love to live next to you if you have agricultural land and feed on your crops.
