10 Common Bird Feeder Predators to Watch For

Backyard bird feeders are a haven for finches, cardinals, chickadees, and other delightful species. But where birds gather, predators often follow. From stealthy stalkers to opportunistic thieves, these threats can wreak havoc on your feeder setup. Knowing who the culprits are—and how to deter them—can help you keep your backyard birds safe.

10 Common Bird Feeder Predators to Watch For

1. Domestic Cats

Silent Stalkers with Deadly Precision

They may curl up adorably on your porch, but domestic cats are stealth assassins in disguise. With feline grace and lightning reflexes, outdoor and feral cats claim the lives of billions of birds each year—making them one of the greatest threats to backyard bird populations worldwide.

Cats don’t just chase birds on a whim—they methodically stalk feeders, crouching low in tall grass or hiding behind garden beds. When birds land or flutter near the ground, a cat can strike in an instant, leaving little time for escape. What looks like a peaceful yard can quickly become a hunting ground if a cat is nearby.

How to Deter Them

Turn your backyard into a safe zone by keeping feeders at least 8–10 feet away from dense shrubs, fences, or garden structures where cats can hide. Use baffles, tall poles, or hanging systems to make climbing nearly impossible. And if you own a cat, consider keeping it indoors—your neighborhood birds will thank you.

2. Hawks

Ambush Predators from the Sky

With razor-sharp talons and eyes that spot a flutter from 100 feet away, hawks bring a different kind of danger to your bird feeder. Species like Cooper’s Hawks and Sharp-shinned Hawks are skilled aerial hunters that turn your peaceful backyard into their personal hunting ground.

These raptors are masters of surprise. They often perch silently in nearby trees or on rooftops, watching for the right moment to strike. When birds gather at feeders, distracted by food and chatter, the hawk swoops in at blazing speed, snatching a meal before the flock even realizes what’s happening. In just seconds, your feeder becomes a scene of chaos—and silence.

How to Deter Them

To give your songbirds a fighting chance, add dense shrubs or brush piles nearby as emergency cover. Creating layers of escape routes can disrupt the hawk’s line of attack. If a hawk becomes a frequent visitor, take down your feeder for a few days to encourage it to move on. With time and care, your yard can once again be a safe space—not a raptor’s buffet.

3. Squirrels

More Than Just Seed Thieves

With twitching tails and acrobatic charm, squirrels may look like harmless backyard clowns, but behind those bright eyes lies a persistent, and sometimes dangerous, feeder invader. Sure, they steal seed—but that’s only the beginning.

During breeding season, squirrels have been known to raid nests, eating eggs and even defenseless hatchlings. Their nimble climbing skills and boundless energy also make them relentless competitors for food, often emptying feeders in hours and driving birds away entirely. Some go so far as to chew through plastic or wood, damaging your setup and making long-term feeding unsustainable.

How to Deter Them

To outsmart these furry gymnasts, install squirrel-proof feeders with weight-sensitive perches or caged designs. Add metal baffles to poles to block their climbs, and position feeders away from trees or rooftops they can leap from. For an extra layer of protection, consider spicy seed mixes—the capsaicin deters mammals but won’t bother your feathered friends.

4. Raccoons

Nighttime Raiders with Dexterous Paws

When the sun sets and the backyard quiets down, raccoons begin their stealthy patrol. With nimble fingers that can unlatch, twist, and pry, these masked bandits are more than just seed thieves—they’re cunning nighttime predators with a taste for eggs, chicks, and chaos.

Raccoons are notorious for raiding birdhouses, reaching inside to snatch nestlings or break eggs with terrifying ease. They’re strong enough to tip over feeders, smart enough to solve latches, and persistent enough to return night after night. Their blend of brute strength and puzzle-solving prowess makes them one of the most challenging backyard intruders to outwit.

How to Deter Them

To keep raccoons at bay, bring feeders indoors at night—their peak prowling hours. Protect birdhouses with predator guards and avoid mounting them on wooden posts raccoons can climb. Instead, use tall metal poles with smooth baffles and hanging systems that offer no grip. In the war for the bird feeder, preparation is your best defense.

5. Snakes

Silent, Slithering Threats to Nests

They move without a sound, blend perfectly into their surroundings, and strike with lethal precisionsnakes are some of the most underrated predators around bird feeders. In warmer regions, species like rat snakes or bull snakes regularly raid nest boxes, devouring eggs, chicks, and occasionally even adult birds.

What makes snakes especially dangerous is their stealth. By the time you realize they’re around, the damage may already be done. They slither up posts, curl into nest cavities, and strike silently, leaving behind empty shells and silent feeders.

How to Deter Them

Prevention starts from the ground up. Mount nest boxes on smooth metal poles, and install snake guards to block climbing access. Keep grass trimmed short, remove brush piles and wood stacks, and avoid placing feeders near dense ground cover where snakes can hide. A clean, open area beneath your feeder gives birds a chance—and snakes fewer opportunities to strike.

6. Blue Jays and Crows

Clever Thieves with a Dark Side

With shimmering feathers and sharp eyes, Blue Jays and crows are some of the smartest birds in your backyard—but don’t be fooled by their beauty or charm. These brainy birds are also opportunistic predators, known for raiding nests to steal eggs and even snatching helpless chicks.

Highly social and incredibly intelligent, they watch feeders closely, learn feeding patterns, and quickly memorize where nests are hidden. Once they find a food source, their persistence makes them notoriously hard to deter. Their large size and assertive behavior also scare off smaller songbirds, dominating the space around your feeders.

How to Deter Them

To keep these avian intruders in check, use feeders with small ports or cages that only allow smaller birds to access the seed. Hanging feeders under dense tree cover, awnings, or eaves also helps reduce visibility from above, making your setup less noticeable to soaring eyes. For especially bold jays or crows, consider temporarily removing feeders or relocating them to a more sheltered area.

7. Chipmunks

Tiny Bodies, Big Trouble

With twitching whiskers and playful antics, chipmunks may look like harmless backyard residents—but don’t underestimate them. These small but sneaky climbers can become serious nest raiders, slipping into birdhouses to eat eggs and even nestlings before you ever suspect they’re a threat.

Their compact size and agility let them squeeze through tight entrances, often going unnoticed until it’s too late. And once they’ve found an easy meal, they’re quick to return, especially if food scraps or spilled seed attract them in the first place.

How to Deter Them

Keep your feeding area clean by removing spilled seed regularly, and avoid using open platform feeders that make access easy. Choose nest boxes with predator-proof entrance holes and mount them on smooth metal poles that chipmunks can’t climb. The less accessible the space, the less likely these ground-dwelling opportunists are to pay a visit.

8. Opossums

Gentle Faces, Hidden Threats After Dark

With their slow waddles and shy nature, opossums don’t exactly scream “predator.” But don’t let their gentle demeanor fool you. These nocturnal scavengers are surprisingly destructive when it comes to nest boxes and feeders, especially under the cover of night.

Opossums are opportunistic omnivores—if they stumble upon eggs, fledglings, or even spilled seed, they’ll help themselves. And once they discover a reliable food source in your yard, they’re likely to return night after night, quietly wreaking havoc while you sleep.

How to Deter Them

Start by removing feeders at night, cutting off their access to easy meals. Secure nest boxes with predator guards on mounting poles, and make sure they’re difficult to climb. Most importantly, never leave food scraps or pet dishes outdoors, as these can lure opossums—and other nocturnal troublemakers—straight to your birds’ doorstep.

9. Rats and Mice

Small Invaders with Big Consequences

They may be tiny, but rats and mice bring big problems to your backyard birding setup. Drawn in by spilled seed and scattered crumbs, these nocturnal intruders don’t just make a mess—they can damage nests, eat eggs, attack defenseless chicks, and spread dangerous diseases to both birds and humans.

Once rodents find an easy food source, they multiply quickly and become incredibly hard to eliminate. Their presence also attracts larger predators like snakes and raccoons, escalating the threat to your feathered visitors.

How to Deter Them

Prevention starts with cleanliness. Use seed-catching trays beneath feeders and sweep up fallen seed daily to remove the rodents’ food source. Avoid placing feeders directly next to buildings, which can give rodents convenient shelter. Keeping your setup clean and elevated is key to keeping these silent intruders far away from your birds.

10. House Sparrows and European Starlings

Invasive Bullies with a Ruthless Streak

They may be common sights at backyard feeders, but House Sparrows and European Starlings are far more than just noisy nuisances. These aggressive, non-native invaders are responsible for widespread harm to native bird populations, using brute force to take over nest boxes, crush eggs, and even kill chicks.

With bold behavior and no fear of humans, these species often outcompete native cavity-nesters like bluebirds, wrens, and chickadees. Once they’ve claimed territory, they defend it relentlessly, leaving native birds displaced or worse—and their sheer numbers make them difficult to manage.

How to Deter Them

Fight back by using nest boxes with entrance holes sized specifically for native birds—too small for sparrows and starlings to enter. Skip open platform feeders, which attract these bullies, and switch to tube-style feeders with small perches. Consistent monitoring and quick removal of sparrow or starling nests can also protect vulnerable native species.

Final Thoughts

Attracting birds to your backyard is rewarding—but it comes with responsibility. By understanding the common predators that lurk around feeders, you can take proactive steps to protect your feathered visitors. From proper feeder placement to using predator-proof equipment, a little planning goes a long way in creating a safe haven for wild birds.
