Feeders / Caged
Caged bird feeders
The least clever mechanism in the category and the most reliable. Nothing to calibrate, nothing to seize, and it works on the light animals that defeat every weight trigger.
A caged feeder surrounds the seed tube with a steel grid whose gaps admit small songbirds and exclude everything larger. Because it works by size rather than weight, it stops chipmunks, red squirrels, starlings and grackles that a weight-activated feeder cannot. The cost is that cardinals and jays also struggle.
Why geometry beats calibration
Every weight mechanism has a threshold, and every threshold has animals underneath it. A cage has no threshold. A chipmunk that walks straight under a Squirrel Buster's trigger simply cannot get through a cage, and neither can a red squirrel, a starling or a grackle.
The second benefit is durability. There are no moving parts, nothing to clean beyond the feeder itself, and nothing that stops working when seed dust gets damp. A cage bought this year behaves identically in five years.

The picks in full
Top pick Small songbirds only
Woodlink Caged Seed Tube Feeder
A cage does not care how heavy the animal is, which is why it beats a weight mechanism against chipmunks and red squirrels as well as gray ones.
Published specifications
- Capacity
- 1 quart (published)
- Feeding ports
- 6
- Cage
- Protective metal
- Named species
- Cardinals, finches, songbirds
Trade-offs
- Exclusion by geometry, so nothing has to be calibrated and nothing wears out
- Also keeps out starlings and grackles, which weight mechanisms often do not
- Six ports on a one-quart tube is a lot of simultaneous feeding for the size
- One quart is a small reservoir; expect to refill often
- Cardinals are named on the listing, but a cage is inherently harder for a larger bird to use
Who it is forA yard with chipmunks, red squirrels or starlings, where a weight trigger will not fire and a cage will.
Skip it ifYou are feeding for cardinals and jays specifically. A cage is a compromise for larger birds by design.

Where these specifications came from
No. 2 Shepherd's hooks and small spaces
Gray Bunny Caged Metal Feeder (GB-6860)
A compact steel cage with published dimensions, which is unusual in this category and makes it the easy one to plan a hook around.
Published specifications
- Dimensions
- 10.25 x 6.25 x 6.25 in (published)
- Feeding ports
- 4
- Construction
- Steel cage, chew-proof and weather-resistant
- Mount
- Hanging; attaches to shepherd's hooks and feeding stations
Trade-offs
- Publishes its dimensions, so you can check it against your hook before buying
- All-metal, so there is nothing on it worth chewing
- Small enough not to overload a light shepherd's hook
- Four ports is fewer than the tube feeders here
- A 6.25 in cage is tight for anything larger than a finch or a chickadee
Who it is forA shepherd's hook or a small feeding station, especially where a heavier feeder would bend the hook.
Skip it ifYou want cardinals. This cage is sized for small songbirds and larger birds will not work it comfortably.

No. 3 Suet and seed in one cage
Caged Dual-Purpose Suet and Seed Feeder
Suet is the format squirrels raid hardest, and a caged suet holder with a seed tray solves both problems with the same steel.
Published specifications
- Capacity
- 2 suet cakes plus 1 lb seed (published)
- Cage
- Metal
- Tray
- Included
- Finish
- Copper
- Mount
- Hanging
Trade-offs
- Two cakes plus a pound of seed covers woodpeckers and songbirds from one hanger
- The cage is also the fix for starlings on suet, which is the second complaint after squirrels
- Tray catches the seed that would otherwise feed the animals under the feeder
- A seed tray under a suet cage collects wet shell and needs emptying
- Copper finish is a strong look that will not suit every setup
Who it is forAnyone feeding suet through the cold months who has watched a squirrel carry an entire cake away.
Skip it ifYou only feed seed. You are paying for a suet cage you will not fill, and a plain caged tube does the seed job for less.

What we would skip
A cage, if cardinals and jays are the point of your feeder
A cage sized to exclude a chipmunk is also a cage a cardinal finds awkward. That is geometry, not a manufacturing flaw. Use a weight-activated feeder with a cardinal ring instead.
What a cage costs you
Birds. That is the honest summary. Woodlink's caged tube names cardinals, finches and songbirds in its listing, and finches will be perfectly happy; a cardinal is a bigger bird working through a fixed grid. Gray Bunny's cage publishes 6.25 in across, which sets the scale clearly.
The standard resolution is two feeders: a cage for the small birds and the light raiders, and a weight-activated feeder with a cardinal ring for the large ones. Between them nothing is excluded that you wanted.
Capacity is usually the compromise
Caged feeders tend to be small, because the cage adds bulk around whatever it surrounds. Woodlink's publishes 1 quart; Gray Bunny's is a 10.25 in tall unit with four ports. Expect to refill more often than you would with a 12 lb hopper, and site the feeder somewhere you do not mind visiting.
The upside of that smaller size is mounting freedom: a light cage hangs comfortably from a shepherd's hook that would bend under a big hopper, which is why a cage is often the right answer on a hook you cannot baffle.
Cages and suet
Suet is where a cage stops being a compromise and starts being the only option. There is no weight mechanism on a suet holder to tune, and a squirrel will carry an entire cake away. A caged suet holder also solves starlings, which arrive at suet in numbers. Suet feeders covers that case.
Placement still matters, slightly less
A cage is the mechanism least sensitive to placement, because nothing about the approach route changes what fits through a grid. But an animal that can reach the feeder can still chew a plastic tube inside the cage, foul the ports and empty the tray below. Cornell's ten-foot rule is still worth following even here — the clearance guide explains why.
How we picked
- We sorted by mechanism first: weight, cage or spin. Those three exclude different animals, and the choice between them is not a quality judgment.
- We used published figures only — seed capacity, port count, dimensions, mechanism. Where a maker publishes nothing, the spec row says so.
- We checked each mechanism against the animal it is calibrated for. A weight trigger tuned for a gray squirrel does not fire for a chipmunk, and we say so rather than implying it does.
- We named at least one product to skip on every page, with the reason.
- We have not tested any of these. How we pick sets out what that does and does not cover.
Everyone in this category says they tested twenty of these. We have not tested any, and we say so. What we did instead: read the manuals, compiled the published specifications, worked out the clearance geometry, and cited every source. The full method is published.
Questions people actually ask
- Do caged bird feeders keep squirrels out?
- Yes, and chipmunks, red squirrels, starlings and grackles as well, because the mechanism is size rather than weight. It is the most reliable exclusion in the category.
- Will cardinals use a caged feeder?
- Awkwardly at best. A cage sized to stop a chipmunk is a tight fit for a cardinal. If cardinals matter, run a weight-activated feeder with a cardinal ring alongside.
- Are caged feeders good for chipmunks?
- They are the only mechanism that works on chipmunks. Weight-activated feeders are calibrated far above a chipmunk's weight and never trigger.
- Do caged feeders need a baffle?
- Less than other feeders do, but an animal that can reach the feeder can still chew it, foul it and clear the tray below. Correct placement is still worth having.
