Understanding Squirrel Nests and How to Identify Them
The idea of birds nesting in our yards brings a sense of warmth and connection to nature. It’s heartwarming to imagine small creatures feeling safe enough to raise their young in our presence. However, not every cluster of twigs and leaves in the trees is a bird’s nest. Sometimes, what we see might actually be a squirrel nest. Learning how to distinguish between the two can help us better understand the wildlife around us.
The Big Ball of Leaves Is a Squirrel Nest
In the fall, it’s common to spot large clusters of leaves on tree branches. While many might assume these are bird nests, they could actually be the work of squirrels. According to Alissa Kakatsch, an assistant turkey and pheasant ecologist with the Wisconsin Department of Natural Resources, squirrels build two types of nests: dens and dreys.
Dens are typically found inside existing structures such as tree cavities, boats, or buildings. On the other hand, dreys are the more commonly seen type of squirrel nest, often located high up in trees. “The standard squirrel nest would be up in trees, and it would be made of twigs, leaves, and other softer material on the inside,” Alissa explains. These nests are usually found 20 to 35 feet high in the treetops, making them quite visible from the ground.
So, if you see a large ball of leaves in the branches of your trees, it might not be a bird’s nest at all — it could very well be a squirrel drey.
What Does a Squirrel Nest Look Like?
One of the key differences between a squirrel nest and a bird’s nest is the size. While both animals can build nests on forked branches, squirrel nests tend to be larger. Additionally, bird nests are often more hidden and secluded, whereas squirrel nests may appear more open and exposed in the branches of trees.
Red squirrels typically build their nests in pine trees, while gray squirrels are known for creating the dreys that are commonly seen in treetops. This distinction helps in identifying which species of squirrel might be using a particular nest.
Squirrel Nesting Behavior
Like birds, squirrels can have multiple litters per year. Their nesting season usually runs from spring through fall, and the young remain in the nest for about 12 weeks before they are ready to leave. Unlike some bird species, squirrels do not mate for life. Instead, females raise their young alone, without assistance from the males.
Understanding this behavior can help us appreciate the effort squirrels put into raising their offspring, even if it sometimes leads to conflicts with humans.
Deter Squirrels From Nesting in Your Yard
If squirrels are eating your birdseed or building nests in areas you’d rather keep clear, it can be frustrating. However, Alissa strongly advises against disturbing or relocating squirrel nests, especially if there are kits (young squirrels) inside. “You wouldn’t want to risk the health or wellbeing of the young, or to risk orphaning them,” she says. She recommends avoiding any interference with nests during March and October, as those months are critical for squirrel activity.
Instead of trying to remove the nests, consider using deterrents. Motion-sensor lights can warn squirrels away, or playing music in the area might serve the same purpose. Sealing off potential entry points to garages, sheds, and other structures can also prevent squirrels from using them as dens.
Coexisting with Squirrels
It’s important to remember that squirrels aren’t intentionally causing trouble. They’re simply doing what they need to survive in the wild, just like birds. With a bit of understanding and appreciation, we can learn to coexist with these creatures. Next time you look up and see a large clump of leaves in your tree, you might be looking at a squirrel family raising their young — one with a bushy tail instead of wings.
Tips for Managing Squirrel Activity
If you’re dealing with squirrels in your yard, there are several strategies you can use to minimize their impact:
- Use motion-sensor lights: These can startle squirrels and discourage them from entering certain areas.
- Play music: A consistent sound can make an area less appealing to squirrels.
- Seal off entry points: Ensure that garages, sheds, and other structures are properly sealed to prevent squirrels from using them as shelters.
- Avoid feeding them: Providing food can encourage squirrels to stay in your yard longer than they would otherwise.
By taking these steps, you can create a more balanced environment where both humans and wildlife can thrive.
