Beavers primarily consume the bark and cambium of various tree species as part of their diet. They’ve a preference for trees such as aspen, poplar, willow, maple, and birch. However, they also eat the bark of alder, oak, black cherry, and apple trees.
In addition to bark, beavers also consume the leaves of woody plants, which serve as the main weaning food for their baby beavers. Mother beavers gradually introduce leaves to their kits while they’re still being fed milk.
Nibbling on twigs and branches, beavers use them to line the bottom of their lodges before winter. During colder periods, shrubs become part of their diet, along with bark and twigs.
In the summer, beavers expand their diet to include ferns, along with bark, twigs, and leaves. They also feed on aquatic plants such as cattails, pondweed, and water lilies.
In the warm months, beavers consume grass and other soft vegetation like clover, watercress, blackberry vines, wild fennel, and mushrooms. However, in times of scarcity, beavers may resort to eating crops like corn, beans, and apples.
It’s important to note that beavers don’t eat wood itself but cut down trees primarily for building purposes. They only consume the bark and cambium, allowing large pieces of wood to fall from their mouths.
Beavers are strictly herbivores and don’t eat meat, fish, or insects.
Leaves of Woody Plants
After consuming the bark and cambium of various tree species, beavers turn their attention to another vital component of their diet: the leaves of woody plants. Leaves play an important role in the beavers’ diet, especially during the weaning process of baby beavers. Mother beavers gradually introduce leaves to their kits while still feeding them milk.
Beavers primarily consume the leaves of woody plants as part of their herbivorous diet. They nibble on the leaves, using their sharp incisors to tear them into smaller pieces before consuming them. The leaves of woody plants provide essential nutrients and fiber to the beavers, aiding in their digestion.
The specific types of leaves that beavers consume can vary depending on the availability and season. During the warmer months, beavers may eat a variety of leaves from trees such as aspen, poplar, willow, maple, and birch. They may also consume the leaves of shrubs and ferns. In times of scarcity, beavers may even resort to eating crops like corn, beans, and apples.
It is important to note that beavers don’t eat the wood itself. Instead, they cut down trees for building purposes and only consume the bark, cambium, and leaves. This unique feeding behavior allows beavers to fulfill their dietary needs while also shaping their environment through tree felling and dam construction.
Twigs and Branches
Twigs and branches serve as an important component of the beaver’s diet, providing both sustenance and materials for their lodges. Beavers are known for their ability to fell trees, and they use the twigs and branches as a source of food.
