Understanding Squirrel Breeding Seasons in Pennsylvania

Squirrels in Pennsylvania, particularly the Eastern Gray Squirrel (Sciurus carolinensis), typically have two breeding seasons each year. These seasons are heavily influenced by weather patterns, food availability, and the overall health of the squirrel population. Understanding these cycles is crucial for homeowners and wildlife enthusiasts alike.

The Spring Breeding Season

The first breeding season generally occurs from late winter to early spring, typically between February and April. This is when squirrels emerge from the colder months and begin seeking mates. Several factors trigger this breeding period:

Increased Daylight Hours: Longer days stimulate hormonal changes in squirrels, prompting them to seek out mates.
Improving Weather: As temperatures rise, squirrels become more active and have more energy for mating and nesting.
Food Availability: The emergence of spring buds, seeds, and other food sources provides the necessary sustenance for pregnant and nursing mothers.

During this period, you may notice increased squirrel activity, including chasing, vocalizations, and nest building. These are all signs that the breeding season is in full swing.

The Late Summer/Early Fall Breeding Season

The second breeding season usually takes place from late summer to early fall, typically between August and September. This allows the young squirrels born in the spring to mature and become independent before the onset of winter. The triggers for this second breeding season are similar to those in the spring:

Abundant Food Supply: The availability of nuts, berries, and other fall foods provides ample resources for pregnant and nursing squirrels.
Milder Temperatures: The cooler temperatures of late summer and early fall are conducive to nesting and raising young.
Hormonal Changes: Similar to the spring, hormonal fluctuations drive the squirrels’ mating behavior.

During this time, you might observe squirrels actively gathering and storing food, a behavior known as caching, as they prepare for the upcoming winter months. This is also when they will be preparing nests for their second litter.

Nesting Habits of Squirrels in PA

Squirrels are meticulous nest builders, creating safe and comfortable homes for their young. These nests, known as dreys, are typically constructed in trees, but squirrels may also utilize attics, sheds, and other structures.

Drey Construction

Dreys are usually made of twigs, leaves, moss, and other soft materials. They are typically located high in trees, providing protection from predators and the elements. Squirrels often choose locations near a fork in the branches for added stability. Our team has observed that squirrels will often use readily available human-made materials like shredded paper or insulation if accessible.

Alternative Nesting Sites

In urban and suburban areas, squirrels may adapt and use alternative nesting sites, such as:

Attics: Attics provide a warm, dry, and sheltered environment for nesting.
Sheds: Sheds offer similar protection and are often easily accessible to squirrels.
Chimneys: Chimneys can be attractive nesting sites, but they can also be dangerous for both squirrels and homeowners.

If you suspect that squirrels are nesting in your home, it’s essential to take action to prevent damage and ensure the safety of both the squirrels and your property. We’ll discuss preventative measures later in this guide.

What to Do If You Find a Baby Squirrel

Finding a baby squirrel can be a heartwarming experience, but it’s important to know how to handle the situation properly. The best course of action depends on the squirrel’s age and condition.

Assessing the Situation

Before intervening, observe the baby squirrel from a distance. Is it injured? Does it appear to be orphaned? Is the mother nearby? According to wildlife rehabilitators, a healthy baby squirrel will often be vocal, attracting the mother’s attention.

If the Squirrel is Injured

If the squirrel is visibly injured, such as having a broken limb or bleeding, it needs immediate professional help. Contact a local wildlife rehabilitator or animal control agency for assistance. They have the expertise and resources to provide the necessary care.

If the Squirrel Appears to be Orphaned

If the squirrel appears to be orphaned, it’s essential to determine if the mother is truly absent. Observe the area for several hours to see if the mother returns. Squirrel mothers often leave their young for extended periods while foraging for food. If, after a reasonable amount of time, the mother does not return, you can consider intervening.

Reuniting with the Mother

If the baby squirrel is healthy and uninjured, the best course of action is to try to reunite it with its mother. Place the squirrel in a safe, sheltered location near where you found it. You can use a small box or basket lined with soft materials. Keep pets and children away from the area to avoid scaring the mother. The mother will usually come back to retrieve her baby. If the mother does not return within 24 hours, contact a wildlife rehabilitator.

Managing Squirrel Populations Around Your Home

While squirrels are fascinating creatures, they can also be a nuisance when they invade homes and gardens. Implementing humane and effective management strategies is crucial for preventing damage and maintaining a harmonious relationship with these animals.

Preventing Squirrel Entry

The best way to manage squirrel populations around your home is to prevent them from entering in the first place. Here are some preventative measures you can take:

Seal Entry Points: Inspect your home for any cracks, holes, or gaps that squirrels could use to enter. Seal these openings with wire mesh, metal flashing, or other durable materials.
Trim Tree Branches: Trim tree branches that overhang your roof or come into close contact with your home. This will prevent squirrels from easily accessing your property.
Install Chimney Caps: Install chimney caps to prevent squirrels from entering your chimney.
Secure Garbage Cans: Secure garbage cans with tight-fitting lids to prevent squirrels from accessing food scraps.

Humane Deterrents

If squirrels are already present on your property, you can use humane deterrents to discourage them from nesting or foraging in unwanted areas:

Motion-Activated Sprinklers: Motion-activated sprinklers can startle squirrels and deter them from entering your garden or yard.
Squirrel-Repellent Plants: Certain plants, such as daffodils, marigolds, and peppermint, are known to repel squirrels.
Noise Deterrents: Loud noises, such as banging pots and pans or playing a radio, can scare squirrels away.

The Role of Wildlife Rehabilitators

Wildlife rehabilitators play a crucial role in caring for injured, orphaned, and displaced squirrels. These professionals have the knowledge, skills, and resources to provide the necessary medical care, nutrition, and rehabilitation to help squirrels return to the wild.

Finding a Wildlife Rehabilitator

If you find a squirrel in need of assistance, contact a local wildlife rehabilitator as soon as possible. You can find a list of licensed rehabilitators through your state’s wildlife agency or online directories. Our research indicates that the Pennsylvania Game Commission maintains an updated list of licensed wildlife rehabilitators.

Supporting Wildlife Rehabilitation

Wildlife rehabilitators rely on donations and volunteers to support their work. Consider donating your time or resources to help these organizations continue their important mission of caring for Pennsylvania’s wildlife. By supporting wildlife rehabilitation, you can contribute to the well-being of squirrels and other animals in need.

Eastern Gray Squirrel: Keystone Species in PA Ecosystems

The Eastern Gray Squirrel plays a vital role in the Pennsylvania ecosystem. They are instrumental in seed dispersal, helping to regenerate forests and maintain biodiversity. Their digging and foraging activities also contribute to soil aeration and nutrient cycling. Understanding their ecological significance highlights the importance of responsible management and conservation efforts.

Seed Dispersal

Squirrels bury nuts and seeds as a food source for the winter, but they often forget where they buried them. These forgotten seeds can then germinate and grow into new trees and plants. This seed dispersal is crucial for maintaining forest health and diversity.

Soil Aeration

Squirrels dig and forage for food, which helps to aerate the soil. This aeration improves water infiltration and nutrient availability, benefiting plant growth.

The Future of Squirrel Populations in Pennsylvania

The future of squirrel populations in Pennsylvania depends on several factors, including habitat availability, climate change, and human activities. Protecting and preserving natural habitats is crucial for ensuring the long-term survival of these animals. By implementing responsible land management practices and promoting coexistence, we can help maintain healthy and thriving squirrel populations for generations to come.
