Bird Seed Types in 2026: Which Seed Attracts Which Species and What to Skip

A 20-pound bag of bird seed at a big-box store costs $8 to $40, depending on what is in it. The cheap bags are mostly red milo, cracked corn, and wheat. The expensive bags are mostly sunflower seed and peanuts. The difference at the feeder is dramatic. A cheap seed mix dumped in a tube feeder will sit untouched while birds scratch out the few sunflower seeds and let the rest fall to the ground. A bag of straight black oil sunflower in the same feeder will be emptied in three days by ten species.

Bird seed is not interchangeable. Each seed type selects for a different group of birds, costs a different amount per bird visit, and produces a different amount of waste. This guide walks through the seven seed types that matter for backyard birding, which birds each one brings in, and what to skip.

Black oil sunflower

Black oil sunflower is the gold standard of backyard bird seed. The shell is thin, the kernel is high in oil and protein, and almost every common backyard songbird eats it. In a single bag, black oil sunflower brings in chickadees, titmice, nuthatches, cardinals, house finches, purple finches, goldfinches (when other seed is not available), blue jays, grosbeaks, woodpeckers, juncos, and many sparrows.

Black oil sunflower works in every feeder type: tube, hopper, platform, and even a bowl on a deck rail. It is the right default seed for any new backyard birder. Expected price in 2026 is $0.80 to $1.20 per pound in 20-to-40-pound bags from farm and ranch stores, or $1.50 to $2.50 per pound in 5-to-10-pound bags from grocery and pet stores.

The trade-off is the shell waste. Each seed leaves a hull on the ground below the feeder. Over a season, the hulls can build up enough to kill grass and require cleanup. For yards where this is a problem, sunflower hearts (shelled black oil sunflower) cost more but produce no hull waste.

Striped sunflower

Striped sunflower is the larger, white-and-gray sunflower seed sold for human snacking and also marketed for birds. The shell is thicker and the kernel is harder to access. Cardinals, grosbeaks, and blue jays handle striped sunflower easily. Smaller birds (chickadees, finches) often skip it because the shell is too hard to crack.

Striped sunflower is occasionally used in mixed seed for selectivity (it filters out smaller birds and squirrels somewhat) but is rarely the primary seed in a yard. For most birders, black oil sunflower outperforms it for cost and species attraction.

Safflower

Safflower is a small white seed with a slightly bitter taste. The bitterness deters gray squirrels, common grackles, blackbirds, and European starlings, while most desired backyard birds eat it without complaint. Cardinals are particularly fond of safflower and many yards switch to safflower specifically to favor cardinals over jays and blackbirds.

Safflower works as a direct replacement for black oil sunflower in any feeder, with the trade-off that fewer total birds will visit (because some species pass on the bitter taste). For yards with persistent squirrel or blackbird problems, switching the main feeder to safflower can transform the species mix within a week. Expected price in 2026 is $1.30 to $2.00 per pound.

Nyjer (thistle)

Nyjer is a tiny black seed imported from Africa, heat-sterilized to prevent germination, and prized by goldfinches, pine siskins, and common redpolls. The seed is too small for most other species to handle efficiently, so a nyjer feeder selects almost exclusively for these finches.

Nyjer requires a dedicated feeder with small ports or a fine mesh nyjer sock. It is the most expensive common bird seed at $3.50 to $5.50 per pound in 2026 and the seed spoils within 6 to 8 weeks if exposed to humidity. In yards with healthy goldfinch populations (eastern, central, and northern North America), nyjer is the highest-yielding seed for those species. In yards without goldfinches, it sits untouched and goes bad.

White proso millet

White proso millet is a small round seed that is the primary food for ground-feeding birds: juncos, native sparrows (white-throated, white-crowned, song, tree, fox), doves, towhees, and indigo buntings. It is also the seed of choice for many migratory birds in spring and fall.

Millet works best in a platform feeder, ground feeder, or scattered directly on the ground. It does not work well in tube feeders (the seed runs out too fast and ground feeders cannot use a tube). Millet is the second most useful seed type after black oil sunflower for most yards. Expected price in 2026 is $0.70 to $1.10 per pound in 20-pound bags.

Red millet, often included in cheap mixed seed, is much less attractive to North American songbirds than white millet. A bag that lists millet without specifying white may be red millet, which is mostly waste.

Peanuts (shelled and whole)

Peanuts in their shell attract blue jays, woodpeckers, and (in some regions) titmice and crows. Shelled peanut pieces work in mesh feeders or platform feeders and attract a wider range: chickadees, titmice, nuthatches, woodpeckers, and Carolina wrens. Peanuts in the shell are easy to add to a platform feeder; shelled peanut pieces require a peanut feeder or wreath.

Peanuts are high in fat and calories, which makes them especially valuable in winter. The trade-off is that peanuts attract bears in bear country and squirrels everywhere. In residential urban yards, this is rarely a problem. In rural and suburban yards near woods, it can be. Expected price in 2026 is $2.50 to $4.00 per pound for shelled, $1.50 to $2.50 per pound for in-shell.

Cracked corn

Cracked corn is the cheapest common bird food at $0.40 to $0.80 per pound. It attracts doves, juncos, native sparrows, towhees, and (unfortunately) starlings, grackles, and pigeons. In yards with a ground-feeder focus and minimal urban-bird pressure, cracked corn on a platform or ground tray is a worthwhile addition. In yards with starling or pigeon problems, it makes those problems worse.

Cracked corn molds quickly when wet. Spread only what will be eaten in one day, especially in humid weather.

Suet (not technically seed, but worth covering)

Suet is rendered beef fat, often mixed with seed, nuts, fruit, or insects. It is the primary food source for woodpeckers in winter and a high-calorie supplement for chickadees, nuthatches, titmice, wrens, and warblers in cold weather.

Suet cakes cost $1.50 to $4.00 each in 2026 and last 1 to 2 weeks in winter, less in summer (it melts above 80°F and goes rancid). For year-round suet feeding, no-melt suet dough (often labeled “summer suet”) is the right choice. Specialty suets with insects, fruit, or nuts attract slightly different species mixes but the main woodpecker group will eat almost any suet.

What to skip

Several seed mixes and types are widely sold and rarely worth buying:

• Red milo. A cheap filler that most North American songbirds will not eat. Common in big-box bird seed bags.
• Wheat. Similar to milo. Mostly ignored by songbirds.
• Oats. Ignored by most backyard birds.
• Generic “wild bird seed” mixes under $1 per pound. These are usually 60 to 80 percent milo, wheat, and cracked corn with a thin sprinkle of sunflower. Birds toss the filler and eat the small percentage of useful seed, wasting most of the bag.
• Bread, table scraps, dry pet food. Not seed and not appropriate for songbirds. Bread fills birds without nutritional value and can hurt nestlings.

Building a seed strategy for a yard

The right seed mix depends on the feeder setup and the bird community. A practical starting strategy for most North American yards:

• Black oil sunflower in the tube feeder. Brings in chickadees, titmice, finches, cardinals, nuthatches.
• White proso millet in the platform feeder. Brings in juncos, sparrows, doves, towhees.
• Nyjer in a thistle feeder (if goldfinches are local). Brings in finches.
• Suet in a cage feeder. Brings in woodpeckers, chickadees, titmice in winter.
• Peanuts (optional) for jays and woodpeckers.

This combination covers 25 to 35 species in most yards across the year. For more on which feeders match these seeds, see our bird feeder types guide.
