Are Birds Arboreal Animals?

Birds are some of the most commonly seen animals around us. We can spot them in our backyards, in the trees, and flying high up in the sky. But where do birds actually live? Are birds considered arboreal animals?

What are Arboreal Animals?

Arboreal animals are those that spend most or all of their time living in trees. The word “arboreal” comes from the Latin word “arbor”, meaning tree.

Arboreal animals have bodies and skills that help them live in trees. For example, many arboreal animals have:

Feet and claws that can grip branches
Long tails for balance
Flexible bodies that can climb and squeeze into spaces
Camouflage colorings to blend into leaves and bark

Some examples of arboreal animals are monkeys, squirrels, chameleons, and sloths. These animals sleep, eat, mate, raise young, and spend most of their lives up in trees. Trees provide food, shelter, safety, and vantage points for arboreal critters.

Are Birds Arboreal?

Yes, birds are considered arboreal animals.

Birds rely heavily on trees for food, shelter, nesting, and more. Although they can also fly and walk on the ground, most birds spend the majority of their time up in trees.

Bird Adaptations For Tree Living

Many features of birds’ bodies enable them to live in trees:

Strong feet and curved claws grip branches. The feet of arboreal birds like woodpeckers have two toes pointing forward and two pointing back to cling to tree trunks.
Lightweight, streamlined bodies allow them to hop and move through branches.
Long tails provide balance and steering. Woodpeckers’ stiff tail feathers help them brace against tree trunks.
Sharp beaks dig out insects and pry apart bark. Nuthatches have special upside-down climbing skills.
Some parrots have a reversible outer toe that helps them climb up and down trees.

Tree Roosting and Nesting

Birds spend hours each day roosting in trees. While roosting, they rest, preen their feathers, escape predators, and watch for food.

Many birds, like crows, roost together in large community groups. But others, like mourning doves, roost alone or in pairs on branches.

Birds also build nests in tree cavities, foliage, and branches to raise their young. Nests provide shelter and safety for eggs and baby birds.

Foraging in Trees

Trees provide a bounty of food for birds. Birds use their specialized beaks and feet to forage and feed on:

Insects like grubs hiding under bark
Spiders and caterpillars on leaves
Nectar from flowers
Fruits, berries, seeds, and nuts
Sap wells drilled by other birds

By living in trees, birds gain access to all of these food sources.

Advantages of Being Arboreal

Living in trees offers many key advantages for birds:

Safety from Predators

The height of trees allows birds to escape from predators like foxes, raccoons, and feral cats. Birds can survey their surroundings and be alerted to approaching danger. Some birds like chickadees even have alarm calls to warn others of predators.

Access to Food and Water

Trees provide food through seeds, nuts, fruits, nectar, and the many insects that live on bark and leaves. Rainwater and dew collect in the nooks of branches for birds to drink.

Prime Nesting Spots

Trees offer cavities, dense foliage, sturdy branches, and other ideal spots to build safe, hidden nests for raising young.

Vantage Points

The elevated views from trees allow birds to watch for food, keep tabs on their territory, and communicate with other birds.

Shelter from Weather

The canopies and hollows of trees provide shelter from rain, wind, and sunlight. Birds can tuck themselves into crevices or dense coverings of leaves.

So while birds are capable of flight, most species are also arboreal animals. Trees perfectly fit birds’ needs for food, shelter, reproduction, and safety. While soaring through the sky, birds always return to rest and roost in their arboreal homes up among the branches.
