Squirrel Nests Vs. Bird Nests: Key Differences Explained

For nature lovers, spotting nests while out on a hike or in your own backyard can lead to wondering—is that a squirrel or bird nest up in that tree? While they share similarities, squirrel and bird nests have some key differences you can look for.

If you’re short on time, here’s a quick answer: Squirrel nests are usually made of twigs and leaves and placed in the fork of tree branches, while bird nests are often cup-shaped and made of materials like grass, moss, feathers, and fur.

Bird nests are more intricate and delicate while squirrel nests are simpler and sturdier.

In this comprehensive guide, we’ll go over the unique features, materials, locations, purposes, and more between these two common types of animal nests found in nature.

What Are the Differences in Appearance and Materials?

When it comes to squirrel nests and bird nests, there are some key differences in both their appearance and the materials used to construct them.

Squirrel Nests are Larger and Bulkier

Squirrel nests, also known as dreys, are typically larger and bulkier compared to bird nests. These nests are built high up in trees and are often found in the forks of branches or nestled against the trunk.

Squirrel nests can measure up to 2 feet in diameter and are made of a combination of twigs, leaves, and moss.

Did you know? Squirrels are known for their resourcefulness when it comes to nest-building. They can adapt their nest construction based on the materials available in their environment, using items such as bark, feathers, and even plastic bags!

Bird Nests are Smaller and Cup-Shaped

In contrast, bird nests are smaller and have a distinctive cup-shaped design. These nests are typically built in tree branches, shrubs, or even on man-made structures such as buildings or lampposts. Bird nests are constructed using a variety of materials, including twigs, grass, leaves, and moss.

Some birds also incorporate feathers, mud, or even spiderwebs to strengthen and secure their nests.

Fun fact: The smallest bird nest is built by the hummingbird. These tiny nests are about the size of a walnut and are often located on the branches of trees or on power lines.

Squirrel Nests Use Twigs and Leaves

Squirrels gather twigs and leaves from their surroundings to build their nests. They carefully interweave these materials to create a sturdy structure. The twigs provide a framework for the nest, while the leaves and moss serve as insulation and provide comfort for the squirrels.

Where Are Squirrel vs. Bird Nests Typically Located?

When it comes to nest building, both squirrels and birds have their own unique preferences for choosing a location. Understanding these differences can help us appreciate the remarkable adaptability and resourcefulness of these creatures.

Squirrels Build Nests in Tree Forks

Squirrels are known for their ability to build nests, known as dreys, high up in trees. They typically choose sturdy tree forks, where the branches meet the trunk, as the ideal location for their nests.

This provides them with a secure and sheltered spot to raise their young and protect them from predators.

These nests are often made from twigs, leaves, and other natural materials, and are lined with soft materials like moss, grass, and fur. Squirrels are skilled builders and will construct multiple nests to use throughout the year, depending on the availability of food and weather conditions.

Birds Nest in Trees and Shrubs

Birds, on the other hand, choose a wider variety of locations for their nests. While some species, like woodpeckers, may also build their nests in tree cavities or crevices, many birds prefer to construct their nests in trees and shrubs.

They look for areas with dense foliage that provides protection and camouflage. Trees with strong branches and shrubs with dense growth are popular choices for birds to build their nests. The specific location may vary depending on the bird species, but they often seek out areas that offer shelter from the elements and predators.

Bird Nest Placement Depends on Species

It’s important to note that bird nest placement can vary significantly depending on the species. For example, some birds build their nests on the ground, while others prefer to nest in cliffs or even man-made structures such as buildings or bridges.

Each species has its own unique nesting requirements and behaviors.

Why Do Squirrels and Birds Build Nests?

Squirrels and birds are both known for their ability to build nests, but the reasons behind their nest-building behavior differ. Let’s explore why these animals construct nests and how their purposes vary.

Squirrels Use Nests for Raising Young

Squirrels primarily build nests to create a safe and cozy environment for raising their young. These nests, known as dreys, are typically constructed high up in trees. Squirrels gather materials such as twigs, leaves, and moss to weave together into a sturdy structure.

The drey provides protection from the elements and predators, ensuring the survival of the squirrel’s offspring. It also serves as a comfortable resting place for the adult squirrels when they are not foraging for food.

Birds Use Nests for Egg-Laying and Raising Chicks

Birds, on the other hand, build nests primarily for the purpose of egg-laying and raising their chicks. The construction of a bird’s nest varies depending on the species. Some birds, like the weaver birds, intricately weave long strands of grass or twigs to create elaborate nests.

Others, like the common house sparrow, utilize materials such as twigs, feathers, and mud to build a more rudimentary nest. Regardless of the construction style, nests provide a safe and stable place for birds to lay their eggs and nurture their young until they are ready to fledge.

Nests Provide Protection from Weather and Predators

For both squirrels and birds, nests offer protection from harsh weather conditions and predators. Elevated nests keep the animals safe from ground-dwelling predators, such as snakes or foxes. The height also helps to shield the nests from flooding during heavy rainfall.

Additionally, the structure of the nest helps to regulate temperature, providing insulation during colder months and ventilation during hotter months.

It’s important to note that while squirrels and birds share some similarities in their nest-building behavior, there are also distinct differences in their nesting habits. Understanding these differences helps us appreciate the unique adaptations and strategies employed by these fascinating creatures.

When Are Squirrel and Bird Nests Built?

Squirrels Build Nests in Late Winter and Early Spring

Squirrels are diligent nest builders and typically construct their nests, known as dreys, during late winter and early spring. This timing allows them to have a safe shelter for their offspring by the time the breeding season begins.

Squirrels often choose the branches of tall trees or the crotches of tree trunks to build their nests. These nests are made of twigs, leaves, moss, and other natural materials, providing insulation and protection from the elements.

Most Birds Nest in Spring and Summer Months

Unlike squirrels, birds tend to build their nests during the spring and summer months. This is because many bird species time their breeding season with the availability of food and favorable weather conditions.

Birds build their nests in a wide variety of locations, including trees, shrubs, cliffs, and even man-made structures like birdhouses. The materials used for constructing bird nests can vary greatly, ranging from twigs and grass to feathers, mud, and even spider webs.

It’s important to note that the exact timing of nest building can vary depending on the species and geographical location. Some birds, such as robins, begin building their nests as early as late winter, while others may wait until the peak of spring or even early summer.

The timing is influenced by factors such as migration patterns, food availability, and temperature.

How Long Do Squirrel and Bird Nests Last?

When it comes to the lifespan of squirrel and bird nests, there are some key differences to consider. Let’s take a closer look at how long these nests typically last.

Squirrels Abandon Nests After Raising Young

Squirrels are known to build nests called dreys, which are typically made of twigs, leaves, and other natural materials. These nests are often located high up in trees, providing safety and protection for the squirrel and its young.

However, once the young squirrels have grown and are able to fend for themselves, the adult squirrels will abandon the nest. This usually happens after a few months, as the young squirrels become independent and venture out on their own.

As a result, squirrel nests are often abandoned and left to decay.

Some Bird Nests Are Used for Multiple Broods

Bird nests, on the other hand, can have a longer lifespan compared to squirrel nests. Many bird species reuse their nests for multiple broods throughout the breeding season. This means that a single nest can be used to raise multiple generations of birds.

For example, a pair of robins may use the same nest to raise multiple broods in a single summer. The nest is continuously maintained and repaired by the adult birds to ensure it remains sturdy and safe for the growing chicks.

Nests Eventually Decay or Are Damaged

Regardless of whether they are squirrel nests or bird nests, all nests eventually decay or become damaged over time. Exposure to the elements, such as rain, wind, and sunlight, can cause nests to deteriorate.

Additionally, predators or other wildlife may damage nests while searching for food or seeking shelter.

It’s important to note that the lifespan of a nest can vary depending on various factors, including the materials used, the location, and the climate. Some nests may only last a few months, while others may remain intact for several years.


Whether you come across a large, twiggy clump or a delicate, cup-shaped cradle, observing animal nests can be a fun way to connect with nature. Now that you know what sets squirrel and bird nests apart, you can more easily identify which fuzzy architect is behind the next nest you spot!

Understanding key differences—like materials used, placement, purpose, and longevity—helps shed light on squirrel and bird behavior and ecology. So keep an eye out on your next woodland hike or just peeking out the window.

You may spot one of these classic signs of spring getting busy building a cozy place for the next generation!
