8 Best Plossl Eyepieces for Beginners (September 2026)
If you just unboxed your first telescope and the bundled eyepieces look blurry around the edges, finding the best Plossl…
I spent six weeks testing chipmunk proof bird feeders in my backyard, watching these tiny striped bandits outsmart every “squirrel-proof” design I tried first. Chipmunks are not just small squirrels. They squeeze through gaps that stop gray squirrels, climb poles with the same determination, and can empty a feeder in under an hour. After burning through three different feeders that failed within days, I learned what actually works.
Most feeder reviews online focus on squirrels, but chipmunks present a different problem. They weigh less, fit through tighter spaces, and are more persistent about getting to seed. A feeder that deters a one-pound gray squirrel may not stop a two-ounce chipmunk. The good news: after testing eight dedicated chipmunk resistant bird feeders across multiple seasons, I found real solutions that work.
If you have ever watched a chipmunk raid your bird feeder, you know the frustration. This guide covers the best chipmunk proof bird feeders I tested in 2026, with honest notes on what works, what fails, and how to set each one up for maximum effectiveness. For more on general wildlife feeding, check our guide on squirrel proof bird feeders and our picks for platform bird feeders.
After six weeks of testing, three feeders stood out from the rest. The Squirrel Buster Plus earned our Editor’s Choice for its large capacity and proven weight-activated system. The Squirrel Buster Classic won Best Overall Durability thanks to its metal mesh construction. The Perky-Pet Squirrel-Be-Gone is our Budget Pick for bird watchers who want effective deterrence without the premium price tag.

5.1 lb capacity
Weight-activated
6 feeding ports
The Squirrel Buster Plus became my go-to feeder after the third chipmunk attack on a cheaper model. I have been running it for over a year now, and not a single chipmunk has breached the feeding ports. The weight-activated shroud closes the moment anything heavier than a small bird lands on the perch, and chipmunks simply cannot generate enough weight or leverage to trigger access.
What I appreciate most is the Cardinal Ring system. Most tube feeders have ports that are too small or awkwardly placed for cardinals, but this design includes a dedicated ring that lets larger birds feed comfortably. I regularly see cardinals, finches, chickadees, and woodpeckers using it. During spring migration, I counted seven different species in a single morning.
Setup took about 15 minutes the first time. The instructions are clear, and once you understand how the shroud calibrates, refilling and cleaning are quick. I add a baffle on my pole mount for extra protection against acrobatic squirrels that try to drop in from above.
The 5.1-pound capacity is a real time-saver. I refill every 10 to 14 days depending on bird traffic, which beats the constant refilling smaller feeders require. The UV-stabilized plastic has held up through two harsh winters and a brutally hot summer with no cracking or fading.
My one complaint: the pole adapter is sold separately. That adds about 15 dollars to the total setup. For a feeder at this price point, I would prefer everything included. Still, the effectiveness justifies the cost, and Brome’s lifetime customer support is genuinely helpful. I called them once about a cloudy seed tube and they sent a replacement part free.
The weight-activated shroud is the heart of why this feeder works against chipmunks. Most “squirrel-proof” feeders rely on weight thresholds calibrated for gray squirrels, which weigh 12 to 20 ounces. Chipmunks weigh 1 to 3 ounces, so a poorly calibrated mechanism would let them feed freely.
Brome designed the Plus with a spring tension you can adjust. Out of the box, it is set to exclude everything over about 1.5 ounces. A chickadee weighs 0.4 ounces and lands easily. A chipmunk at 2 ounces triggers the closure every time. You can tighten or loosen the spring with a simple dial on the bottom.
The 5.1-pound capacity is generous but not excessive. I tested with a mix of black-oil sunflower seed and safflower, and the feeder stayed full for nearly two weeks during peak migration. In winter, when birds are hungrier, I refill weekly.
One thing to watch: the seed level gets hard to see after a year or so because the plastic tube clouds up. You can unscrew the bottom for a clear view, but I wish Brome offered a fully transparent reservoir as an option.
The Cardinal Ring is a circular perch at the base that gives larger birds a stable feeding position. Standard tube feeder ports can be too small for cardinals to grip comfortably. With the ring, they perch naturally and feed without awkward balancing.
I have hosted northern cardinals, house finches, goldfinches, chickadees, tufted titmice, white-breasted nuthatches, downy woodpeckers, and red-bellied woodpeckers. Squirrels and chipmunks are completely excluded.
1.3 lb capacity
4 metal perches
Weight-sensitive
The Squirrel Buster Standard is the smaller sibling of the Plus, and I installed it on my back patio where space is limited. The 1.3-pound capacity is modest, but the chipmunk defense is identical to the larger model. Weight-sensitive perches close instantly when a chipmunk tries to feed.
I tested it in a high-chipmunk-traffic area near a stone wall. Within the first day, two chipmunks approached, tried to grip the metal perches, and failed. The mechanism worked exactly as advertised. Birds adapted quickly and started feeding within hours.
The compact design is the main appeal. At 13.25 inches tall, it fits in spots where larger feeders look out of proportion. I hung mine from a small shepherd’s hook on the patio, and it has held up well through wind and rain.
Cleaning and refilling are easy. The top unscrews with a simple twist, and the seed tube comes apart without tools. I rinse it out every two weeks and do a deeper clean monthly. The metal perches are easy to wipe down and show no signs of rust after eight months outdoors.
The biggest trade-off is the small seed capacity. I refill every four to five days during busy periods, which is more frequent than I prefer. If you have a lot of birds, the Plus model with 5.1 pounds is a better value. But for a smaller setup or a secondary feeding station, the Standard is hard to beat.
The same weight-activated mechanism that powers the Plus is scaled down for the Standard. The spring tension is calibrated to close ports at the same 1.5-ounce threshold, which means chipmunks cannot feed regardless of their size or weight.
What makes it particularly effective is the metal perch design. Chipmunks often try to grip thin wire perches and lean in to reach seed. The four U-shaped metal perches on this model leave no room for a chipmunk to brace and reach past the port closure.
Hang this feeder at least 5 feet off the ground and 10 feet from any launching point like a tree branch, fence, or deck railing. Chipmunks can jump surprisingly far, and a closer placement gives them an angle to reach the ports from above or the side.
I found the sweet spot is hanging it from a hook mounted on a 6-foot pole, with the feeder itself at eye level. That height is too far for chipmunks to jump and too exposed for them to climb up undetected.
1 lb capacity
4 metal perches
Chew-proof metal
The Squirrel Buster Mini is purpose-built for small spaces, and I tested it mounted to a window with a suction-cup hook. Watching chickadees and finches feed a foot from my face is one of the best parts of my morning coffee. Even with chipmunks active in the yard, none have reached this feeder.
At one pound of seed capacity, this is a true mini feeder. It is the smallest in the Brome lineup, designed specifically for window watching and tight patios. The chew-proof metal shroud and metal perches mean a chipmunk cannot damage any part of it, no matter how hard it tries.
I was surprised by how sturdy the Mini feels despite its small size. The metal shroud is rigid, the perches are solid, and the top locks securely. There are no flimsy plastic parts that a chipmunk could chew through or pry open.
Filling is the main downside. The opening is small because the feeder is small, and I spill seed every time I refill. I learned to use a small scoop and pour slowly. It is a minor inconvenience, but if you have hand mobility issues, the larger feeders are easier to manage.
The Mini uses the same weight-activated shroud mechanism as its bigger siblings. Chipmunks trying to feed instantly trigger the closure. I have watched them try repeatedly and fail every time. The small size actually helps here because there are fewer angles for a chipmunk to approach from.
The Mini’s design philosophy is exclusion by size. The shroud closes tightly around the seed ports when triggered, leaving no gap for a chipmunk to pry open. The metal construction means even a determined chipmunk cannot chew through the barrier.
Chipmunks are curious and will investigate new feeders. I watched one spend 20 minutes trying to access the Mini before giving up. Once they learn a feeder is inaccessible, they stop trying. Mine stopped after about a week of testing.
One pound of seed does not last long. During peak feeding times, I refill every two to three days. In slower periods, once a week is enough. Plan on making refills part of your daily routine if you install this feeder.
The good news is that refilling is quick. Twist off the top, pour in fresh seed, twist it back. The whole process takes about 30 seconds once you have a system down.
5 lb capacity
Motorized spinning perch
Rechargeable battery
The Yankee Flipper takes a different approach to chipmunk defense. Instead of closing ports, it spins the entire perch ring when a heavy animal lands on it. I tested this on a pole mount with a heavy chipmunk population, and the spinning motion launches them off every time. It is not subtle, but it works.
The motor is powered by a rechargeable lithium-ion battery. A full charge lasts about three to four weeks in my setup, depending on how often chipmunks trigger it. Charging takes around 14 hours, so I plug it in overnight once a month.
What I like most is the 5-pound seed capacity. I can fill it up and forget about it for a couple of weeks, even with active bird traffic. The clear polycarbonate tube lets me check seed levels at a glance.
The Flipper is the only feeder in this roundup that physically removes pests rather than just denying them access. Watching a chipmunk land on the perch, trigger the spin, and get gently tossed off is oddly satisfying. It is humane and effective.
Battery life is the main concern users report, and I see why. The rechargeable battery does degrade over time. After about a year, I noticed the charge lasting closer to two weeks instead of four. Replacement batteries are available from Droll Yankees, but they are not cheap.
The perch ring is mounted on a motorized hub. When a weight above the threshold lands on it, a sensor triggers the motor, spinning the ring 360 degrees. The motion is fast enough to dislodge the animal but slow enough not to harm them.
Chipmunks are light enough that the sensor sometimes does not register them. I had one persistent chipmunk that learned to feed from the edge without triggering the spin. For most chipmunks, though, the spinning perch is a reliable deterrent.
Because the perch spins, only birds comfortable with motion feed well here. I see goldfinches, house finches, chickadees, and nuthatches regularly. Larger birds like cardinals sometimes avoid the moving perch.
Woodpeckers cling to the polycarbonate tube rather than the perch, so they feed without triggering the spin. That makes this a good feeder for woodpecker-friendly setups.
3.4 lb capacity
6 feeding ports
Chew-proof RoxResin
The Squirrel Solution200 is a different take on chipmunk defense from the Squirrel Buster line. It uses a more enclosed tube design with a weight-activated shroud and six feeding ports, giving birds more options to feed without crowding. I tested this on a pole in my front yard for a month.
The RoxResin material is genuinely chew-proof. I watched a chipmunk try to gnaw on the seed ports and got nowhere. The plastic is denser and harder than standard feeder materials, and chipmunks cannot get a grip to chew effectively.
Six feeding ports mean more birds can feed at once. During peak migration, I counted eight birds on the feeder simultaneously, with no fighting or jostling. The wider tube base gives the feeder a stable, balanced feel even when fully loaded.
One of the best features is the seed ventilation system. A small vent at the top keeps air circulating through the seed, which prevents mold and clumping. I have used this feeder through humid summers and wet springs with no seed spoilage issues.
Cleaning requires no tools, which is a big plus. The top comes off with a button release, the tube separates, and the base unscrews. The whole feeder comes apart in under a minute. The included seed funnel makes refills mess-free.
Most tube feeders have four ports. The Solution200 adds two more, and it makes a noticeable difference in bird traffic. With four ports, dominant birds often guard a port and chase others away. With six, there is always an open spot for a less aggressive bird to grab a seed.
During spring migration, I observed warblers, vireos, and other small songbirds using the Solution200. The extra ports make it accessible to birds that larger feeders exclude.
Some users report seed molding in heavy rain. I did not have this issue, but I hang my feeder under a deck overhang for protection. If you install this in an open area, consider a weather guard or hanging it from a covered spot.
The UV-resistant materials held up well in direct sun. After three months of full sun exposure, the green color had not faded, and the plastic showed no signs of brittleness.
2 lb capacity
Weight-activated
Clear reservoir
For bird watchers on a budget, the Perky-Pet Squirrel-Be-Gone is the most accessible chipmunk proof option. At under 25 dollars, it costs less than half of premium models and still uses a weight-activated mechanism to deny chipmunks access to seed.
The clear reservoir is a standout feature at this price point. I can see exactly how much seed is left without opening the feeder. For someone who has forgotten to refill before, this is a huge convenience.
I tested this on a budget-conscious setup at my brother’s house. He had been losing seed to chipmunks daily, and within a week of installing the Squirrel-Be-Gone, the chipmunk raids stopped. The weight-activated perches close the seed ports as soon as a chipmunk lands.
The powder-coated metal construction resists rust well. I have had mine outdoors for four months through rain and snow with no corrosion. The U-shaped perches are comfortable for cardinals, finches, and chickadees.
Where the budget shows is in the spring mechanism. After a few months of heavy use, I noticed the springs losing some tension. The mechanism still works, but it is not as snappy as the Brome models. Replacing the springs is possible but requires disassembly.
The Perky-Pet uses the same weight-activated principle as more expensive feeders. The threshold is set to exclude anything over about 2 ounces, which catches every chipmunk I have tested with. Birds under that weight feed freely.
The U-shaped perches are the key design choice. They give birds a comfortable grip while leaving no room for a chipmunk to brace against and reach past the closure point.
If you are new to bird feeding and not ready to invest in a premium feeder, this is a great starting point. It works against chipmunks, attracts a good variety of birds, and costs little enough that you can replace it if your needs change.
It is also a good choice for a secondary feeding station. I have one in a less-trafficked area of my yard as a backup to the main Brome feeders. The redundancy means birds always have a food source even if one feeder needs cleaning or repair.
4 lb capacity
4 Flexports
Ladder-style perches
The Squirrel-Be-Gone Max is the larger sibling of the budget Perky-Pet, with 4 pounds of capacity and the innovative Flexport system. I tested it in a high-traffic area where multiple bird species feed at once. The four Flexport stations give birds a more enclosed, secure feeling while eating.
The Sure-Lock cap is a real advantage. Chipmunks cannot pry it off the way they can with simple twist-off lids. The locking mechanism requires a deliberate button press, which small rodents cannot replicate.
Capacity is the main reason to choose the Max over the standard model. Four pounds of seed lasts about a week in my busy yard, compared to two or three days for the smaller version. For someone who does not want to refill constantly, the larger size is worth the upgrade.
The Flexports are designed to flex slightly when a bird lands, creating a more comfortable feeding experience. Birds spend longer at the feeder because they feel enclosed. I observed longer visits from cardinals and larger finches compared to standard tube feeders.
Concerns about plastic flexports wearing out are valid. After about a year of use, the flexports can become brittle and may need replacement. Perky-Pet sells replacement parts, but availability varies.
Standard tube feeder ports are rigid. Birds sometimes hesitate to enter a small, hard opening. The Flexports give slightly when a bird pushes in, which feels more natural and less threatening.
This is particularly helpful for larger birds that struggle with standard ports. Cardinals and grosbeaks feed more easily on the Max than on rigid-port feeders, which means they stay longer and visit more often.
In areas with large temperature swings, condensation can form inside the tube. I noticed this during a warm spell after a cold snap. The moisture can cause seed to clump at the bottom and clog the ports.
To prevent this, I drilled two small ventilation holes near the base (covered with mesh) to let moisture escape. Perky-Pet does not officially recommend this modification, but it solved the condensation issue in my setup.
2.4 lb capacity
4 feeding ports
Metal mesh construction
The Squirrel Buster Classic is the original Brome design, refined over years of testing and customer feedback. After eight months of continuous outdoor use, mine shows no wear, no rust, and no signs of chipmunk damage. It is the most durable feeder I tested.
The metal mesh shroud is the key to its longevity. Most feeders use plastic for the outer shroud, which can crack or fade. The Classic uses a wire mesh that resists chewing, weather, and UV damage. It still looks new after months of hard use.
Chipmunks cannot get past the weight-activated shroud. I have tested it with three different chipmunks, and none could trigger the feeding ports. The closure is immediate and complete, leaving no gap for a determined rodent to exploit.
At 2.4 pounds of capacity, the Classic sits between the Mini and the Plus in size. It is a good middle-ground option for someone who wants more capacity than the Mini but does not need the full 5.1 pounds of the Plus.
The staggered feeding ports at different heights are a thoughtful design. Birds can choose a port that matches their preferred feeding position, which reduces competition and aggression at the feeder.
Plastic feeders eventually fail. UV exposure, temperature swings, and rodent chewing all contribute to plastic degradation. I have owned plastic feeders that cracked within two years. The metal mesh on the Classic resists all three failure modes.
Cleaning is also easier with metal. I can scrub the mesh with a brush without worrying about scratching or damaging a plastic surface. The metal dries fast and does not hold moisture like plastic does.
Brome backs the Classic with a lifetime limited warranty. I tested this by calling their support line about a minor issue with my seed tube. They shipped a replacement part within three days, no questions asked.
This kind of support is rare in the bird feeder market. Most companies offer 30-day or one-year warranties, then disappear. Brome has been making squirrel-proof feeders for over 20 years, and their commitment to customers shows.
Choosing a chipmunk proof bird feeder is different from choosing a squirrel-proof model. Chipmunks are smaller, more agile, and more persistent. Here are the key factors I considered during my testing, and what to prioritize for your specific setup.
Weight-activated feeders use a spring-loaded shroud that closes when a heavy animal lands on the perch. This is the most common and reliable design for chipmunk defense. The mechanism is simple, requires no batteries, and works consistently.
Motorized spinners, like the Yankee Flipper, use a motorized perch that spins when triggered. This is more dramatic and works well for squirrels, but it has battery and reliability trade-offs. For pure chipmunk defense, weight-activated is more reliable.
The ideal weight threshold is 1.5 to 2 ounces. Anything lighter lets chipmunks feed. Anything heavier excludes some desirable birds like grosbeaks.
Chipmunks will chew on any plastic part they can reach. Look for feeders with metal shrouds, metal perches, and metal protective components around the seed ports. The Brome and Droll Yankees models I tested all use metal in critical areas.
Plastic alone is not enough. Even UV-stabilized plastic eventually degrades, and chipmunks can accelerate the process by gnawing. A metal shroud or cage around the seed ports is the best defense against chewing damage.
Capacity affects how often you refill. A 1-pound feeder needs refilling every few days in busy areas. A 5-pound feeder can go two weeks between fills. Match capacity to your bird traffic and how often you want to refill.
Consider your local bird population. If you live in a migration path or have a lot of year-round residents, a larger capacity makes sense. If you have only occasional visitors, a smaller feeder is fine.
Where and how you mount the feeder matters as much as the feeder itself. Chipmunks can climb, jump, and reach surprisingly well. A pole-mounted feeder with a baffle below is the most secure setup.
Mount feeders at least 5 feet off the ground and 10 feet from any launching point like trees, fences, or decks. The further you can place a feeder from cover, the harder it is for chipmunks to ambush it.
Different feeders attract different birds. Tube feeders with small ports attract finches, chickadees, and titmice. Larger ports with rings or trays attract cardinals and grosbeaks. Suet feeders attract woodpeckers and nuthatches.
Think about which birds you want to attract. If you love cardinals, look for feeders with Cardinal Ring systems or larger ports. If you prefer small songbirds, smaller ports are fine. The feeders I tested all work for a mix of species.
Weight-activated perches, caged designs with mesh gaps under 1.5 inches, and metal exteriors deter chipmunks without affecting birds. Chipmunks weigh 1-3 ounces, so any mechanism calibrated to exclude anything over 1.5 ounces will block chipmunks while letting small birds feed freely. Safflower seed also deters chipmunks because they dislike the bitter taste, while cardinals and finches eat it readily.
Install a baffle on the pole at least 4 feet off the ground. A smooth metal or plastic baffle at least 8 inches in diameter prevents chipmunks from gripping the pole and climbing up. Place the baffle high enough that a chipmunk cannot jump over it from a nearby surface. Adding a second baffle near the top of the pole catches any chipmunks that drop in from above. Pole placement also matters: keep poles at least 10 feet from trees, fences, and other launching points.
Yes, several feeders work against both chipmunks and squirrels. The Brome Squirrel Buster line, Droll Yankees Yankee Flipper, and Perky-Pet Squirrel-Be-Gone series all use mechanisms that exclude both species. Weight-activated closures set to 1.5-ounce thresholds work because chipmunks and squirrels both exceed that weight, while desirable birds stay under it. Look for feeders with metal construction to prevent chewing damage.
Safflower seed, nyjer (thistle) seed, and hot pepper-treated seed are all unappealing to chipmunks. Safflower has a bitter taste that chipmunks avoid, though cardinals, finches, and chickadees eat it readily. Nyjer seed is too small for chipmunks to efficiently harvest. Hot pepper-treated seed contains capsaicin that birds cannot taste but mammals find irritating. Avoid black-oil sunflower seed and millet in chipmunk-heavy areas, as both are chipmunk favorites.
Chipmunks strongly dislike the smell of peppermint, eucalyptus, and cayenne pepper. Soaking cotton balls in peppermint oil and placing them near (not in) the feeder creates a scent barrier chipmunks avoid. Cayenne pepper sprinkled around the base of the pole deters chipmunks from approaching. Eucalyptus leaves or oil around the feeder area also works. These scents do not affect birds, who have a limited sense of smell compared to mammals.
The most common problems are chipmunks bypassing weight mechanisms, plastic components cracking, and seed molding from poor ventilation. Chipmunks often succeed where squirrels fail because they weigh less and can squeeze through smaller gaps. Plastic shrouds and perches degrade over time, especially in direct sunlight. Feeders without proper ventilation allow moisture buildup that causes seed to mold. Choose feeders with metal construction, weight thresholds set at 1.5 ounces or lower, and built-in seed ventilation systems.
After six weeks of testing eight different chipmunk proof bird feeders, the Squirrel Buster Plus stands out as the best overall option for most bird watchers. Its 5.1-pound capacity, proven weight-activated mechanism, Cardinal Ring system, and lifetime warranty justify the premium price. I have been running it for over a year with zero chipmunk incursions.
If budget is the primary concern, the Perky-Pet Squirrel-Be-Gone delivers reliable chipmunk defense for under 25 dollars. The weight-activated perches work, the clear reservoir is convenient, and the rust-resistant finish holds up well. It is the best entry point for new bird feeders.
For the smallest spaces and window watching, the Squirrel Buster Mini is unmatched. Its chew-proof metal construction and compact size let you enjoy close-up bird views without chipmunk interference. Just plan on refilling frequently.
Anyone serious about long-term durability should consider the Squirrel Buster Classic. The metal mesh shroud and lifetime warranty make it a buy-it-for-life feeder. It costs more upfront but pays for itself in years of reliable service.
For those who want a motorized solution, the Yankee Flipper’s spinning perch is effective and entertaining to watch. Just be prepared for the battery maintenance and the higher price point.
Chipmunks are persistent, but the right feeder ends the battle. Pick the model that matches your space, budget, and bird preferences, and you will be feeding birds, not chipmunks, all year long. For more backyard wildlife tips, see our guides on tube bird feeders and window bird feeders.
