Bird Seed to Species to Feeder Matrix
Seed choice is the fastest way to change which birds visit — and which ones do not. Most feeder problems are not solved by a new feeder; they are solved by changing the seed. The column most people need is the third one: what each seed keeps away.
1. Seed to species matrix
| Seed | Attracts | Generally avoided by | Feeder style needed |
|---|---|---|---|
| Black-oil sunflower | Chickadees, titmice, nuthatches, cardinals, house and purple finches, grosbeaks, jays, woodpeckers | Very little — this is the universal seed | Tube, hopper or platform |
| Striped sunflower | Cardinals, jays, grosbeaks, larger-billed birds | House sparrows and blackbirds, which struggle with the thicker shell | Hopper or platform |
| Hulled sunflower / sunflower chips | Everything that eats sunflower, plus smaller-billed birds | — | Tube or platform; spoils fastest when wet |
| Safflower | Northern cardinals, chickadees, titmice, house finches, grosbeaks | Grackles, starlings, blackbirds — and usually squirrels | Hopper or platform |
| Nyjer (thistle) | American goldfinches, pine siskins, common redpolls, house finches, juncos | Grackles, starlings and blackbirds show little interest | Fine-port tube or mesh sock |
| White proso millet | Juncos, mourning doves, native sparrows, towhees, buntings | Most tube-feeder specialists ignore it | Ground or low platform |
| Milo / sorghum | Some western ground-feeding birds | Widely rejected by eastern backyard birds — classic cheap-mix filler | Ground |
| Cracked corn | Jays, doves, quail, sparrows, ground feeders | — | Ground or platform, small amounts only — spoils and moulds quickly |
| Peanuts (whole or pieces) | Blue jays, woodpeckers, titmice, nuthatches, chickadees | — | Mesh peanut feeder or platform — keep dry |
| Suet | Woodpeckers, nuthatches, chickadees, wrens, some warblers | — | Suet cage; use no-melt dough in heat |
| Mealworms (dried or live) | Bluebirds, robins, wrens, chickadees | — | Small dish or dedicated mealworm feeder |
| Nectar (sugar water) | Hummingbirds; orioles take a weaker mix | — | Nectar feeder — no dye, clean frequently in heat |
| Fruit (orange halves, grape jelly) | Orioles, catbirds, tanagers, mockingbirds | — | Fruit spike or jelly dish, small servings |
2. Feeder style to what it serves
| Feeder | Seed it suits | Serves | Watch for |
|---|---|---|---|
| Tube, standard ports | Black-oil and hulled sunflower | Finches, chickadees, titmice, nuthatches | Ports clog when seed gets damp |
| Tube, fine ports / mesh sock | Nyjer | Goldfinches, siskins, redpolls | Nyjer goes stale; buy small quantities |
| Hopper / house | Sunflower, safflower, mixes | Cardinals, jays, grosbeaks, finches | Keep the reservoir dry, or the bottom layer cakes |
| Platform / tray | Almost anything | The widest range, including ground feeders | Needs drainage; clean often |
| Ground or low tray | Millet, cracked corn | Juncos, doves, sparrows, towhees | Offer only what is eaten in a day |
| Suet cage | Suet cakes and plugs | Woodpeckers, nuthatches, wrens | Tail-prop designs deter starlings better |
| Peanut mesh | Whole or shelled peanuts | Jays, woodpeckers, titmice | Peanuts must stay dry |
| Nectar feeder | Sugar water | Hummingbirds, orioles | Needs the most frequent cleaning of any feeder |
| Weight-triggered / caged | Sunflower, safflower | Small songbirds | Excludes squirrels and larger birds mechanically |
3. Solving the four common problems
| Problem | Change the seed to | Or change the feeder to |
|---|---|---|
| Squirrels emptying the feeder | Safflower | Weight-triggered or caged feeder, mounted away from jump routes |
| Grackles and starlings taking over | Safflower or nyjer | Caged feeder; tail-prop suet feeder |
| House sparrows dominating | Striped sunflower or nyjer | Tube with short perches; remove tray attachments |
| Seed being kicked out and wasted | A straight seed instead of a filler-heavy mix | Tray under the feeder to catch spill |
| Nothing visiting a new feeder | Black-oil sunflower | Move it within about 10 ft of cover and wait — new feeders take weeks |
4. Seasonal notes
- Late summer and fall: high-fat seeds matter as migrants fuel up. Nyjer draws goldfinches, which moult to their drab winter plumage and are often mistaken for a different bird.
- Winter: suet and black-oil sunflower carry the most calories per visit. Keep a water source ice-free if you can do it safely.
- Spring: mealworms for bluebirds during nesting; nectar feeders up ahead of the local hummingbird arrival.
- Hot weather: nectar spoils fast and suet melts — switch to a no-melt formulation and shorten refill intervals.
5. Method note
The attract and avoid columns reflect long-standing, widely replicated backyard-feeding observations from ornithological and extension sources, and they describe strong tendencies rather than absolutes. Regional bird populations differ, and a hungry animal will eat something it normally refuses. Species listed are common backyard feeder birds of the continental United States; your local list will be a subset. This page makes no claim about deterring wildlife reliably and is not a pest-control recommendation.
6. Frequently asked
Which bird seed do squirrels not like?
Safflower is the seed most often used to discourage squirrels, and it is also generally avoided by grackles, starlings and blackbirds while remaining popular with cardinals, chickadees, titmice and house finches. Results vary by region and by how hungry the local squirrels are.
What seed attracts goldfinches?
Nyjer, often sold as thistle, is the classic goldfinch seed. It also draws pine siskins, common redpolls and house finches. It needs a fine-port tube feeder or a mesh sock, because the seed is tiny.
What is the single best all-round bird seed?
Black-oil sunflower. Its thin shell and high fat content make it usable by the widest range of backyard species, from chickadees and nuthatches to cardinals and finches.
Why do birds ignore my seed mix?
Cheap mixes are bulked with milo, wheat and cracked corn, which most eastern backyard birds reject. They kick it out to reach the sunflower, and the rejected filler accumulates under the feeder and spoils. A straight seed or a sunflower-heavy mix wastes far less.
How often should feeders be cleaned?
Clean feeders regularly and whenever seed gets wet or clumped, and rake up spilled hulls beneath them. Nectar feeders need the most frequent attention in hot weather. Follow the cleaning guidance from your local wildlife or extension authority.
