What Does A Squirrel Nest Look Like? An Introduction To Squirrel Nests

What does a squirrel nest look like? In the vast tapestry of nature's creations, the dwellings of animals hold a particular fascination for many. Among these, the squirrel nest, a marvel of natural architecture, stands out for its intricacy and function. Understanding what squirrel nests looks like not only enriches our knowledge of these agile creatures but also deepens our appreciation for the complexity of wildlife living among us. This article delves into the fascinating world of a squirrels nest, offering a comprehensive exploration of their characteristics, construction, and variations.



The Quintessential Squirrel Nest: Features and Structure


What is a squirrel nest called? They’re known scientifically as 'dreys,' and are primarily constructed by tree squirrels to serve as shelters and breeding sites. These nests are typically found high up in trees, offering protection from predators and harsh weather conditions. A standard squirrel drey is a feat of natural engineering, showcasing the squirrel's ability to utilize available resources effectively. A squirrel nest looks like oversized clumps of leaves and twigs, similar to an elongated bird’s nest.



Materials Used in Squirrel Nest Construction


Squirrels are not picky when it comes to the materials they use for their nest. The primary components of a squirrel nest include twigs, leaves, moss, and bark. During the height of Covid, some squirrels were using discarded masks to build nests. These materials are intricately woven together to form a sturdy and insulated shelter. The inner lining of the nest is often made from softer materials such as grass, feathers, and even shredded paper, providing a warm and comfortable environment for the occupants.



Appearance and Location


Squirrels are masterful builders, constructing intricate homes high up in trees amidst the pine needles. These nests are truly a marvel of engineering, encircling soft materials like moss and leaves with sturdy twigs. Although they may appear as a jumbled mass of materials from a distance, closer inspection reveals a spherical structure with an impressive average of 12 to 20 inches in diameter. Located high in the branches, these nests are usually 30 to 45 feet above the ground, providing the perfect vantage point for curious squirrels to keep a watchful eye on the surrounding area. It's no wonder that these homes in the trees are a squirrel's preferred choice for safety and security!


Types of Squirrel Nests


Squirrels are skilled architects who create their very own homes in nature. They are known to build two main types of nests: the drey and the cavity nest. Squirrels choose the type of nest they build based on various factors, such as the season, the type of coniferous trees available, and their personal preferences. Regardless of which one they choose, squirrels always add an outer shell of leaves or bark to disguise their nest as part of the surrounding environment.



Drey Nests


Drey nests are fascinating examples of squirrel architecture, not to be confused with bird nests. Squirrel nests look like messy ball of twigs, damp leaves, moss, and loosely woven grass, and represents the culmination of several days of hard work and dedication. Female squirrels will build one nests located in the tree branches, with an outer shell on the strong limbs of a sturdy tree. Despite appearing haphazard, these structures are a testament to the skill and resourcefulness of squirrels. Within each drey lies a hollow centre, lined with shredded bark, grass, and other soft materials where squirrels settle down and enjoy the safety and protection of the thick outer layer. Watching a nesting squirrel toil away on their nests is a sight to behold, and serves as a reminder of the amazing resilience and ingenuity of nature. Squirrels sometimes have a second or even a third nest nearby, for safety reasons, or to store extra food. If you find chewed pine cones on the ground, that could indicate squirrel nests up above.



Cavity Nests


In harsh weather conditions, especially during the winter months, many animals seek shelter in a tree trunk or in tree cavities. For example, grey and red squirrels build their nests in a variety of locations, including within tree cavities. These cavities can be natural or excavated, and offer an extra layer of protection from the weather elements and, more importantly, other animals. Some squirrels even build their nest with softer materials like bark or moss, ensuring maximum comfort. However, because cavity nests are not as widely available as other types of tree-dwelling homes, competition is fierce among squirrels and other species for these spots. These coveted spaces are highly sought after due to their convenience and safety factor. Unlike other squirrel nests that require constant maintenance and attention, these ready-made homes only require a little interior decorating to make them feel complete. Squirrels often choose tree cavity nests because they provide a sense of security that other squirrel dreys cannot. The design of the cavity itself protects the squirrels from predators, keeping them safe in their cozy abode. Plus, with the damp leaves, twigs, and branches nearby, lining the inside of the nest is a breeze. No wonder a tree cavity nest is the ultimate squirrel dream!



Seasonal Variations in Nesting


Amid the treetops of Brampton’s forested areas and the tranquil suburbs, nesting squirrels exhibit a captivating display of adaptability and ingenuity. These agile creatures are not static architects; they craft their nests with a keen sensitivity to the rhythm of Mother Nature. When the air hums with the warmth of summer, squirrel dreys dot the boughs of the trees—nesting material intricately woven between tree branches, forming aerial homes that allow for breaths of cooling air. If you do notice a grey squirrel or see a squirrel’s nest in a tree, wait quietly and watch….you might be rewarded with the sight of grey squirrel babies peeking out of a nest located high up, depending on the time of year.

Yet, as autumn slowly turns to the early winter weather, so shifts the priorities of a bushy-tailed squirrel. No longer is a high-altitude nest desirable. Instead, you’ll notice squirrels seek out other nests that are within a tree trunk, carving out a cavity nest that cradles warmth, snug against the winter's chill. Some squirrel species, such as the Eastern gray squirrels (or grey squirrels), might even share a nest among themselves, although female squirrels with babies will not invite others in. Then when early spring rolls around, the cycle begins all over again. Each squirrel's nest showing the resilience and wisdom of these charming creatures.



Where Do Squirrels Build Nests In Cities?


When you think of squirrels, you may picture them darting up trees in a forest or park. But did you know that red squirrels have also adapted to city life? These creatures have learned to build nests in local wood structures. You may notice them near bird feeders and pine trees, as these are prime spots for gathering food. Interestingly, red squirrels typically horde food. However, this behaviour can sometimes cause problems, as their stash of pine cones may be built inside electrical boxes or too close to electrical wires, creating a hazard for them and potentially causing power outages for humans. Despite this, it's fascinating to see how these fuzzy creatures are able to adapt to their changing environments.



Nesting Habits and Reproduction


Beneath the tree canopy where squirrels live, painstaking labour unfolds as the breeding season beckons. Mother squirrels, architects by nature's design, look for the perfect nest—a cradle high above ground, hidden from the probing eyes of other animals. A squirrel drey located at the junction of sturdy branches not only provide refuge but also a vantage point, safeguarding her second litter of the year against predators. If a mother squirrel feels her squirrel’s nest is no longer safe, she will move her young to a new location.

With patience woven into every fiber, strands of grass are interlaced into a spherical messy ball. Intruders find it difficult to gain access, as the nests, fortress-like, are masterfully concealed. Inside, the delicate whispers of new life are heard, testament to the resilience and continuation of their kind. Herein lies the beauty of instinct—the nesting habits that ensure survival, seamlessly entwined with the cycle of reproduction. The design and location of the nest play a crucial role in the survival of the offspring, protecting them until they are mature enough to venture outside.



Conservation and Coexistence


As we go about our day-to-day lives, it's easy to overlook the fact that we share our environment with countless wild animals. Squirrels, one of the most common and recognizable critters we come across, are particularly fascinating due to their elaborate and unique nest-building habits. These little creatures are quite particular when it comes to their homes, preferring to nest in specific types of trees, especially those with high canopies and plenty of foliage. By noticing squirrel activity and paying attention to the tell-tale signs of their nests, we can avoid causing unintentional harm during their breeding season in the late summer. With a little bit of understanding and a lot of shared space, all of us - squirrels included - can flourish together in this beautiful world we call home.



Conclusion: A Glimpse into Squirrel Engineering


The squirrel nest is a testament to the ingenuity and resilience of these nimble creatures. From the selection of nesting materials to the strategic choice of location, every aspect of a squirrel nest reflects a keen adaptation to the environment. By exploring the intricacies of squirrel nests, we not only gain insight into the lives of these fascinating animals but also develop a deeper appreciation for the complexity of nature itself. As we walk through wooded areas or glance up at the coniferous trees in our neighborhoods, we are reminded of the remarkable world of squirrels that thrives above us, hidden in plain sight.
