Yesterday, I shared my excitement about upgrading my wildlife photography setup by camping in my new Scamp camper at Mount Magazine State Park here in Arkansas (Upgrading My Wildlife Photography Setup: From Teardrop to Scamp). The experience was even more rewarding than expected, thanks to an unexpected visitor right at my campsite—a busy Gray Squirrel building a leaf nest in the tree next to where I had parked my camper. As a wildlife photographer, this was a perfect opportunity to observe and photograph the squirrel’s industrious behavior while relaxing at my campsite.
The Art of Nest Building
Gray squirrels are fascinating creatures, especially when it comes to their nest-building skills. They construct two primary types of nests: leaf nests, known as dreys, and tree cavity dens.
Leaf Nests (Dreys): These are what I witnessed being built at my campsite. The process starts with the squirrel weaving twigs together to create a sturdy base. Once the framework is in place, they reinforce it with damp leaves and moss, which helps solidify the structure. The outer shell is completed by weaving in more twigs and stuffing additional materials like leaves and moss. The result is a large, sturdy nest that can span up to two feet wide. The inside is lined with softer materials, such as shredded bark and grass, creating a cozy space for the squirrel to rest. These nests are typically built in the forks of tree branches, at least 20 feet above the ground, providing safety from predators and a good vantage point.
Tree Cavity Dens: While I didn’t see one of these at my campsite, it’s worth noting that gray squirrels often choose tree cavities, like natural hollows or abandoned woodpecker holes, especially during the winter. These dens offer better protection from harsh weather and predators, making them a preferred choice when the temperatures drop.
Nesting Behavior: A Seasonal Symphony
Squirrels are most active in nest-building during the fall as they prepare for winter. However, they also build nests in the summer, which is what I witnessed. It’s interesting to note that they don’t just build one nest; they maintain several within their home range. This gives them options in case one nest becomes infested with parasites or is disturbed by predators. These additional nests also provide temporary shelter as they go about their daily activities.
Seasonal Use of Nests: While leaf nests like the one I observed are primarily used in the summer, squirrels prefer tree cavities in the winter for better insulation. Despite the colder weather, squirrels do not hibernate. They remain active throughout the year, using their nests for shelter and warmth at night.
Social and Reproductive Aspects of Squirrel Nesting
Generally, squirrels are solitary nesters, meaning they each have their own nest. However, during mating seasons, males and females may share a nest briefly. Additionally, when temperatures drop significantly, squirrels might share a nest to conserve body heat, showing their adaptability in the face of harsh conditions.
Raising Young: Female gray squirrels use these nests to raise their young. The nests provide a safe environment for the babies, who stay in the nest until they are about 10 to 12 weeks old. Once they are ready, they leave the nest to explore the world on their own.
Final Thoughts
Witnessing a Gray Squirrel build its nest at my campsite was a reminder of the incredible adaptability and resourcefulness of wildlife. As a wildlife photographer, it’s moments like these that make the outdoors so rewarding. Sitting there, with my camera in hand, I couldn’t help but marvel at the squirrel’s dedication and skill in creating a safe and comfortable home.
So, next time you’re out in nature, take a moment to observe the small wonders around you. You never know what you might see—or learn—while enjoying the great outdoors.
I love those little rascals
