You likely know that squirrels have an appetite for nuts, seeds, and pinecones. But you may be surprised to discover that squirrels occasionally raid birds’ nests and eat their eggs! As opportunistic omnivores, squirrels will eat eggs when other food sources are scarce.
Though disturbing, this behavior alone doesn’t significantly impact most songbird populations. However, you can take steps to protect backyard birds if squirrel egg predation becomes a problem. Installing predator guards on birdhouses and positioning feeders away from vegetation can deter these fuzzy-tailed egg thieves.
While exclusion is difficult, providing alternative foods like corn cobs may also distract squirrels from raiding nests. So although squirrels do eat bird eggs, some simple solutions can reduce negative interactions between squirrels and nesting birds in your backyard.

Do Squirrels Eat Bird Eggs?
You bet your beak those sneaky tree rats’ll swipe your babies if you’re not vigilant! Squirrels are notorious opportunistic eaters that will gladly consume eggs and hatchlings if given the chance. They especially target vulnerable robin, cardinal, and dove nests filled with protein-rich eggs and tiny hatchlings.
While not their preferred food, squirrels will devour any unprotected eggs or defenseless nestlings they can access if hungry enough.
This predation can have a minor impact on local songbird populations. However, the biggest threat to our feathered friends is actually habitat destruction from human activity, not squirrels. Providing alternative food sources like squirrel feeders stocked with nuts and seeds is a great way to divert squirrels away from raiding nests during breeding season.
Strategically placing these feeders can lure squirrels away from bird boxes and prime egg-laying spots.
You can further protect nests by installing predator guards, baffles, and other deterrents on birdhouses and nesting trees. Smooth, slippery poles also prevent squirrels from climbing. While squirrels may opportunistically eat eggs and baby birds, smart prevention and diversion tactics can stop this nest raiding and reduce their impact on your yard’s bird population.
With some care and planning, you can keep both squirrels and songbirds happy and coexisting peacefully!
Why Would a Squirrel Eat Bird Eggs?
There are a couple of main reasons a squirrel might eat bird eggs.
For one, squirrels are opportunistic eaters that will consume eggs if they can access them. Though not their preferred food, squirrels may raid nests and eat eggs or tiny hatchlings if they are hungry enough.
This is especially likely during times when their normal foods like nuts and seeds are scarce. A squirrel that finds an unprotected robin nest or dove nest is liable to steal and eat the eggs inside if given the chance.
So accessibility and scarcity of normal foods drive some squirrels to take advantage of easy protein sources like bird eggs.
The other circumstance when squirrels eat eggs more often is during the spring nesting season. This is when mother birds like robins and doves are sitting on eggs and protecting fledgling chicks in the nest.
Hungry squirrels frequently raid nests at this time of year, prompting anxious mother birds to abandon the nest. By driving off the adult bird, the squirrel gains access to eat the eggs and defenseless baby birds in the unattended nest.
So the vulnerability of nests each spring, coupled with the squirrel’s opportunistic nature, compels them to eat readily available eggs. Discouraging squirrels from nest raiding in spring helps ensure baby birds hatch safely when mother birds can properly incubate their eggs.
What Kind of Eggs Do Squirrels Eat?
Now let’s discuss what specific kinds of eggs squirrels tend to target. You’ll find that squirrels are opportunistic and will eat whatever eggs they can easily access. This includes the eggs of common backyard birds like robins, cardinals, doves, and chickens.
Squirrels raid nests and eat the eggs of these smaller songbirds if they can reach them. They particularly like robin eggs and have been known to severely impact robin nesting success when population numbers are high.
Though squirrels prefer nuts and seeds, they will turn to readily available sources of protein like eggs when other food is scarce. You’ll notice increased egg predation during cold winters when nuts and seeds are limited.
Along with eggs, squirrels will eat tiny, dead hatchlings if desperate, but these are not a preferred food source. The availability of accessible songbird eggs and nests is what drives squirrel egg predation more than a craving for eggs per se.
Limiting easy access to nests through deterrents and providing alternative food sources are the best ways to curb this behavior if it becomes problematic in your yard.
Do Squirrels Eat Baby Birds?
With their keen senses, squirrels can spot helpless hatchlings. Though not their preferred meal, squirrels are known to opportunistically raid nests for nutrient-rich eggs and tiny, vulnerable nestlings.
Three key factors lead squirrels to attack bird nests:
- Hunger: Squirrels raid nests more frequently in times of famine or drought when nuts and seeds are limited.
- Accessibility: Squirrels target easy-to-reach nests in bushes, low branches, and on the ground.
- Defenselessness: Newly hatched birds are immobile, naked, and blind. They lack the ability to escape or fight back when a hungry squirrel comes along.
Though disturbing to witness, squirrel predation of baby birds has a negligible effect on overall bird populations. Far greater threats are habitat destruction, window collisions, and cats. Deterrents like capsaicin spray, predator decoys, and baffles on birdhouses can prevent squirrels from devastating nests during the critical spring hatching season when parent birds are most vulnerable.
With some awareness and planning, you can protect the baby birds in your own backyard.
Do Squirrels Attack Bird Nests?
You must watch that rascally rodent’s ravenous rampage. Squirrels will indeed attack backyard bird nests when given the chance. These bushy-tailed bandits see eggs and hatchlings as easy pickings to satisfy their appetite.
While not their preferred fare, squirrels will opportunistically raid nests, especially in spring and summer when birds are breeding.
To protect vulnerable nests from squirrel predation, take preventative measures. Install predator guards, smooth any climbing surfaces, and increase nest height where possible.
Squirrels that attack bird nests:
Nest Location: Ground/Low Shrub
Attack Risk: High
Preventative Measures: Thorny branches, pruning
Nest Location: Cavity (Tree/Birdhouse)
Attack Risk: Moderate
Preventative Measures: Metal baffles, smooth pole
Nest Location: Elevated (Tree branches)
Attack Risk: Low
Preventative Measures: Prune access, increase height
Proactively feed squirrels away from bird sites so they’re less inclined to pilfer. Strong scents like peppermint oil can also repel curious squirrels from nest areas.
Do Squirrels Eat Adult Birds?
Despite popular belief, squirrels rarely prey on adult birds. Though perceived as pests, gray squirrels do not significantly impact most bird populations. Their small size limits them to raiding nests for eggs, not attacking full-grown birds.
Squirrels lack the strength and predatory instinct to subdue healthy adult birds. Their opportunistic nature leads them to steal unattended eggs and occasionally eat weak hatchlings. But attempting to kill mature birds would be dangerous and energy-intensive compared to foraging for plant foods.
While invasive gray squirrels compete with native UK red squirrels, research shows neither species substantially reduces songbird numbers. Most birds are too quick and nimble for squirrels to catch. Squirrels mainly focus on easily accessible food like seeds and dropped fruit.
Though they may snack on eggs, their impact is minor compared to habitat loss from human activity.
Instead of viewing squirrels as malicious bird killers, focus on deterrents like capsaicin dust and owl decoys. Providing alternative foods away from nests also reduces incentive for squirrels to raid.
A balanced ecosystem includes peaceful coexistence of squirrels, birds, and humans.
Do Squirrels Hurt Bird Populations?
We’re reassured their effect’s slight; more worrisome is habitat loss. Many small birds face threats from predators like opportunistic squirrels, yet their populations remain stable overall. Songbirds and other desirable backyard birds continue thriving despite the occasional tragedy of a squirrel raiding a nest for eggs or chicks.
While startling, such incidents barely influence total bird numbers. Squirrels mainly eat plant foods; meat comprises a tiny portion of their diet. They might raid nests when other foods are scarce, but don’t rely on eggs or baby birds.
Even invasive grey squirrels in the UK failed to decrease songbird populations. The true danger comes from habitat destruction. As humans pave over meadows and cut down trees, we decimate the places birds need to feed, nest, and raise young.
No amount of squirrel deterrence can offset losing woods and marshes to development. The best approach encourages peaceful coexistence between our furry and feathered friends. Simple precautions like smooth poles and predator effigies protect backyard nests.
Establishing alternative feeding stations keeps squirrels away during nesting seasons. While they occasionally snack on eggs and chicks, squirrels pose a limited threat compared to habitat loss. We must preserve wilderness areas if we wish songbirds to thrive for generations.
What Birds Are Most at Risk From Squirrel Predators?
Small songbirds like robins and cardinals are most vulnerable to squirrel predation when building open cup nests. Their unsupervised nests in trees and shrubs provide easy access for clever, hungry squirrels seeking a nutrient-dense protein source.
The most common target species include:
- Robins – One of the earliest nesters, robins often lose eggs and nestlings to squirrels before other birds start nesting.
- Cardinals – With messy, compact nests low in shrubs, cardinal eggs and babies are easily spotted and consumed by squirrels.
- Chickadees – Small and abundant, chickadees are a frequent target. They nest in tree cavities but squirrels can access the opening and eat the eggs.
While squirrels take advantage of easy opportunities for fresh food, research shows their opportunistic predation does not significantly reduce overall songbird populations. The biggest threat to bird numbers is habitat destruction. Providing squirrels with supplemental feed, concealing nest sites, and using deterrents can help minimize losses.
How to Stop Squirrels From Eating Bird Eggs
You can take several steps to prevent hungry squirrels from raiding bird nests in your yard. Place birdhouses in discreet locations, increase pole heights, and use baffles or narrowed openings. Additionally, try feeding squirrels away from nests and utilize deterrents like capsaicin or peppermint oil to redirect them elsewhere.
By following these tips, you will be able to enjoy birdwatching while minimizing harm to your feathered friends during nesting season.
Put Birdhouses in Places Not Easily Visible to Squirrels
Conceal your nests from those rascally rodents. Avoid open birdhouse placements visible to all varieties of curious mammals. Instead, position boxes behind tree bark or clustered branches. This minimizes visibility to gray squirrels while still allowing parent birds access.
With strategic positioning, you can protect the birds’ nests from the squirrel population.
Make It Difficult for Squirrels to Reach Your Birdhouses
You’re going to have to get creative to keep those bushy-tailed egg snatchers from scaling up to those nests. Maybe try lubricating the pole, using baffles, or installing nest boxes on smooth surfaces.
Whatever it takes to protect those unhatched babies, mama bird is counting on you. Consider squirrel-proof bird feeders, squirrel traps, or relocating birdhouses to deter the squirrel problem and keep your feathered friends safe this season.
Feed Squirrels With a Squirrel Feeder
Make feeding those small rascals easy with a dedicated feeder. Providing an abundant source of nuts, seeds, and dried corn can satisfy a squirrel’s appetite. When their food needs are readily met, they will be less inclined to pilfer bird nests.
Watching the creatures scurry and dine at a feeder offers a fun diversion too. Feeding squirrels may promote healthier populations, so thoughtfully meet their seasonal needs.
Deter Squirrels to a Different Part of Your Yard
Place a tall statue near their usual route. Give them an alternate path using mildly spicy foods, fresh water, and shelled peanuts placed far from the bird feeders and nests.
Use Deterrents to Keep Squirrels Out of Your Yard Altogether
Surround your yard with strong scents like peppermint oil to deter squirrels altogether. Intersperse cotton balls soaked in pure peppermint oil around your yard’s perimeter. The potent smell repels squirrels while remaining harmless. Strategically place them near birdhouses, gardens, and squirrel entry points.
Refresh monthly, especially during the spring nesting season when eggs and hatchlings become targets. Though not foolproof, it’s an easy, humane way to discourage squirrels from entering and snacking in your yard.
Tips to Keep Squirrels Away From Your Birdhouses
Plaster your birdhouses with strong-smelling essential oils like peppermint to drive squirrels away this nesting season. The strong scent will deter squirrels from approaching while being harmless to nesting songbirds in the food chain.
Other tips include:
- Install squirrel baffles on poles and trees to prevent climbing. These plastic or metal barriers are situated below the birdhouse to block access to squirrels. Adjustable baffles allow you to regulate the distance between the baffle and birdhouse as needed.
- Use a pole predator guard below the baffle. This smooth plastic cylinder further obstructs climbing.
- Consider relocating birdhouses to new spots annually. This prevents squirrels from staking out last year’s nests. Place houses at least 10 feet high on thin poles with no low branches. This mimics natural nesting sites beyond the reach of squirrels.
Invasive squirrel species, in particular, can decimate songbird populations if left unchecked. Implementing humane deterrents preserves your birdhouses as a safe haven for nesting pairs to hatch chicks.
With some creativity and persistence, you can outsmart these quick critters. Protect precious eggs from harm without harming squirrels in return.
Frequently Asked Questions (FAQs)
How often do squirrels raid bird nests?
Squirrels sometimes raid bird nests to eat eggs when other food is scarce, but this is not their normal behavior. Provide alternative food sources during nesting seasons and utilize deterrents to help minimize squirrel disturbances.
Overall, habitat destruction by humans poses the greatest threat to bird populations.
What time of year are birds most vulnerable to squirrel predation?
The spring and summer nesting season is when birds are most vulnerable to squirrel egg predation. During this time, conceal nests high in trees, use deterrents, and provide alternative food sources to protect vulnerable eggs and hatchlings from opportunistic squirrels seeking an easy meal.
Do urban squirrels eat more eggs than rural squirrels?
You’re more likely to see urban squirrels eating eggs. They live at higher densities, face more food scarcity, and encounter more accessible nests. However, don’t assume rural squirrels never raid nests when hungry. All squirrels opportunistically take eggs they can reach.
What scent deterrents work best for keeping squirrels away?
Use skunk scent spray, fox urine spray, or capsaicin and peppermint oils. Position them around birdhouses during nesting season. These harsh scents naturally deter curious squirrels. Rotate repellents regularly for best results.
How do you safely remove squirrels that keep attacking birdhouses?
Install predator decoys near nests. Use strong scents like peppermint to deter squirrels. Cover openings tightly and smooth surfaces. Offer squirrels alternative food sources away from nests.
At the end of the day, you have to accept that squirrels are a part of the natural ecosystem and, like any other animal, must forage to survive. While their predation of bird eggs isn’t ideal, proactive deterrence and discouraging squirrels from nest access will prevent most conflicts.
We must strike a balance between conservation and compassion in dealing with nature’s challenges. With some common-sense solutions for safeguarding nests, both birds and squirrels can thrive side by side.
