As winter sets in across New York, nature continues its quiet transformation. Among the many changes, a curious sight may catch your eye: a large ball of leaves nestled high in the branches of trees. While it might seem like a bird’s nest, it’s actually something much more intriguing – a drey, a winter home for squirrels. These nests are not only an essential survival tool for squirrels but also a fascinating part of New York’s wildlife ecosystem.
What Is a Drey?
A drey is a nest built by squirrels to shelter themselves from harsh winter conditions. It’s typically composed of twigs, leaves, moss, and other natural materials. Squirrels construct these nests with remarkable care, usually choosing a location near the trunk of a tree or in the fork of branches for stability. The structure is designed to provide insulation and protection from the elements. Unlike birds, squirrels do not hibernate during the winter months. Instead, they rely on these dreys for warmth and safety.
Although dreys are commonly found in wooded areas, they can also be seen in urban parks and backyards throughout New York, particularly in areas with an abundance of trees. The construction of a drey is a testament to the squirrel’s adaptability and resourcefulness. It also serves a critical function in protecting young squirrels during the coldest months.
Squirrels in New York: Species and Habits
New York is home to several species of squirrels, with the most common being the Eastern Gray Squirrel and the Red Squirrel. Both species are known for building dreys during the winter, though they may also seek out other sheltered spots like tree cavities or attics for additional warmth. New York is also home to two species of flying squirrels—the Northern Flying Squirrel and the Southern Flying Squirrel—which are much rarer but equally skilled at constructing elaborate nests.
Squirrels in New York typically do not hibernate, unlike some animals that completely retreat during the winter months. Instead, they remain active, gathering food in the fall to sustain them throughout the cold. While they may spend much of the winter in their dreys, they occasionally venture out in search of food, especially during periods of milder weather. Squirrels are opportunistic feeders and will often forage for nuts, seeds, and even fungi.

The Drey: A Winter Survival Tool
As the temperature drops, the drey serves as the perfect shelter to keep squirrels warm. The dense construction of leaves and twigs traps air and creates a cozy, insulated space. This insulation is vital, as it helps maintain body heat and protects the squirrel from freezing temperatures, especially during the long, frigid winters that are common in New York.
Dreys are often built before the cold sets in, as squirrels prepare for the harsh winter months ahead. They typically begin construction in the fall, collecting materials such as dried leaves, moss, and bark. These nests can be as large as a basketball in diameter, providing ample room for squirrels to nestle in when they are not out foraging.
Interestingly, dreys are not only used during winter. They also serve as safe places for squirrels to give birth and raise their young in the spring. The drey’s high position in the trees offers protection from predators and helps the young squirrels stay safe until they are old enough to fend for themselves.
Why Are Dreys Important?
Dreys play a crucial role in the survival of squirrels throughout the winter months. Without these nests, squirrels would have to rely on more precarious shelters, which might not offer the same level of protection from the elements or predators. Additionally, the location of the drey, high in the trees, ensures that squirrels can avoid ground-based predators, such as coyotes or domestic pets.
In urban areas like New York City, the drey provides a vital connection between the squirrels and the natural environment. These nests are often found in parks or green spaces, which serve as havens for wildlife amid the bustling city. The presence of squirrels and their dreys in these spaces can also be an indicator of the health of the local ecosystem.

What to Do If You Spot a Drey
If you’re out walking in the woods or through one of New York’s many parks this winter, keep an eye out for these fascinating nests. While it’s best not to disturb the squirrels or their homes, observing from a distance can offer an incredible glimpse into the lives of these resourceful creatures. And if you’re lucky, you might even spot a squirrel as it enters or exits its drey, preparing for a day of foraging or resting.
If you do find a drey in your own backyard or near your home, it’s important to remember that these nests are protected under state law. Squirrels are considered wildlife, and disturbing their nests could result in unintended harm to the animals. You can find more information about how to handle wildlife in your area on NYC Wildlife.
Conclusion
The squirrel drey is a remarkable testament to the ingenuity and resilience of wildlife. In New York, where winters can be brutal, these carefully constructed nests provide squirrels with the necessary shelter and insulation to survive the colder months. Next time you’re out enjoying the winter scenery, take a moment to appreciate the little ball of leaves high in the tree – it’s a squirrel’s winter secret to survival.
The drey serves not only as a home for these adaptable creatures but also as a reminder of the importance of preserving green spaces for wildlife, even in the heart of urban areas. Whether in the woods or the city, the squirrel drey is a natural marvel that continues to captivate nature lovers and casual observers alike.
