Feeder Types
Bird feeder materials, and which parts must be metal
The question is not which material is best. It is which part is made of what.
By Scooter M. · Published · Last updated
The parts squirrels chew — ports, caps and hangers — should be metal. The body can be UV-stabilized polycarbonate or cedar without penalty. Avoid all-plastic feeders with molded ports: squirrels open them, and thin plastic goes brittle in a freeze.

“Best bird feeder material” is a real search and the useful answer is component-level rather than product-level. Almost every feeder worth buying is a mix, and what matters is which material is used where.
The three materials
| Material | Good at | Fails at | Use it for |
|---|---|---|---|
| Powder-coated metal | Chew resistance, freeze resistance, longevity | Weight, cost, and it can rust where the coating is chipped | Ports, caps, bases, hangers, poles, baffles |
| UV-stabilized polycarbonate | Seeing the seed level, light weight, not shattering | Squirrel teeth; cheap grades yellow and craze in sun | Tube bodies |
| Cedar | Rot resistance without treatment, looks, no condensation | Chewing, and it needs drainage designed in | Trays, hoppers, suet cage panels |
| Thin untreated plastic | Being cheap | Everything else — chewing, UV, freezing | Nothing you intend to keep |
The rule that matters
Metal wherever a squirrel puts its teeth. That means the feeding ports, the cap and the hanger. A polycarbonate tube with metal ports survives; the identical tube with molded plastic ports gets opened, and you buy it twice.
Droll Yankees publishes exactly that combination for the Onyx line: a UV-stabilized polycarbonate tube with a black cap, base and ports made of heavy metal and powder-coated. That is the shape to look for.
Cedar, and why it is not just decorative
Cedar is naturally rot-resistant, which is why it is used for trays and hoppers that sit in the rain — Nature's Way publishes premium cedar with stainless steel screws and a powder-coated galvanized steel seed tray on its platform feeder. The wood handles the weather; the metal handles the part that holds wet seed.
What cedar does not handle is chewing. A cedar feeder in a squirrel yard needs a baffle more than a plastic one does, because a squirrel will widen a cedar port rather than crack it.
Materials and cleaning
The material decides how easy the every-week-or-two clean is. Smooth polycarbonate wipes out. Powder-coated metal takes hot soapy water fine. Cedar cannot be soaked indefinitely and should be scrubbed, rinsed and dried rather than left in a bucket. Whatever the material, it must come apart — the cleaning routine is here.
What about glass, ceramic and copper?
They exist, they look good, and they are decorative purchases rather than functional ones. Glass and ceramic break when a full feeder comes off a hook in a gale. Copper looks excellent and is soft. None of them is wrong; just buy them knowing you are buying the look.
The short version
- Metal ports, cap and hanger. Non-negotiable if squirrels exist.
- Polycarbonate or cedar body, both fine.
- Stainless or coated hardware, because rust seizes the parts you need to open.
- Drainage designed in, whatever it is made of.
- Nothing thin, cheap and unrated — you will buy it again in a year.
What we would buy for this
#1 · Best material mix
Droll Yankees Onyx Clever Clean 18" Sunflower Tube Feeder
Droll Yankees · A plain, well-made first tube feeder
A straightforward polycarbonate tube whose base twists off in seconds, which is the single feature that decides whether a feeder gets cleaned or quietly turns into a health problem.
Published specifications
- Seed capacity
- 2 lb
- Height
- 18"
- Feeding ports
- 4
- Materials
- UV-stabilized polycarbonate tube; powder-coated metal cap, base and ports
- Cleaning
- Twist-and-release removable base; one-touch top opening
What it does well
- The removable base turns cleaning from a chore into a two-minute job
- Metal ports resist squirrel chewing better than all-plastic tubes
- Short perches keep grackles and jays off without excluding finches
What it does not
- No squirrel mechanism at all, so this feeder needs a baffle or a pole
- Four ports fill up quickly at a busy station
Specifications above come from the manufacturer's own published listing: Droll Yankees Onyx Clever Clean published specifications.
#2 · Best cedar build
Nature's Way Cedar Platform Tray Feeder (CWF3)
Nature's Way · Cardinals, jays, doves and anything that will not use a tube
An open cedar tray with a removable screen bottom, which is the honest answer for the big ground-feeding birds a tube feeder quietly excludes.
Published specifications
- Dimensions
- 12" x 12" x 2.25"
- Capacity
- 3 quarts
- Materials
- Premium cedar, stainless steel screws, powder-coated galvanized steel seed tray
- Drainage
- Removable screen tray for drainage and airflow
What it does well
- Cardinals and jays use it immediately; they often will not use a small tube port
- The screen bottom drains, which is the difference between a tray and a puddle
- Nothing to break, and it cleans in a minute
What it does not
- Completely open to squirrels, so this one belongs on a baffled pole or nowhere
- Seed is exposed to rain even with drainage, so put out small amounts
Specifications above come from the manufacturer's own published listing: Nature's Way CWF3 published specifications.
#3 · Best steel build
Woodlink Absolute II (model 7536)
Woodlink · Big capacity and cardinals — the hopper answer to squirrels
A double-sided steel hopper whose counterweighted perches drop a shield over the seed tray when something heavy lands, and it holds twelve pounds so it barely needs attention.
Published specifications
- Seed capacity
- 12 lb
- Dimensions
- 16" W x 11.25" H x 13.5" D
- Feeding ports
- 6 (both sides)
- Mechanism
- Two counterbalanced perches, adjustable to three weight settings
- Materials
- Steel and acrylic
What it does well
- 12 lb capacity means refills measured in weeks, not days
- Perch tension adjusts for light, medium or heavy birds
- The long perch rail suits cardinals, which will not use a small tube port
What it does not
- Twelve pounds of seed is heavy, so the hook or pole has to be rated for it
- Seed sitting for weeks in wet weather is how mold starts; a big hopper needs the same cleaning discipline as a small one

Common questions
What is the best bird feeder material?
A mix: metal ports, cap and hanger with a UV-stabilized polycarbonate or cedar body. Material choice matters per component, not per feeder.
Are metal bird feeders better than plastic?
For the parts squirrels chew, yes. For the body, a good polycarbonate tube is lighter, lets you see the seed level, and does not rust.
Are cedar bird feeders any good?
Cedar is naturally rot-resistant and excellent for trays and hoppers. It is not chew-resistant, so it needs a baffle where squirrels are active.
Do plastic bird feeders last?
UV-stabilized polycarbonate does. Thin untreated plastic goes brittle in a freeze and yellows in sun, and squirrels open molded plastic ports.
