Best Bird Seed for Cardinals

For most yards, the best bird seed for cardinals is plain black oil sunflower, and Wagner’s Four Season bag, listed at a minimum of 14% protein and 24% fat, is an easy, filler-free choice. If grackles, starlings or squirrels are emptying your feeder, switch to safflower or a sunflower and safflower blend such as Wagner’s Cardinal Blend. For a clean patio, pay more for shelled sunflower kernels.

How we chose

We have not physically tested these seeds. This list is based on research: ingredient lists and guaranteed analyses from manufacturers and major retailers, feeding guidance from the Cornell Lab of Ornithology and Project FeederWatch, and patterns in verified owner feedback. We favored products whose ingredients match what cardinals actually eat, and we avoided mixes padded with milo, red millet or cracked corn, which Project FeederWatch notes often go to waste. We also looked for recurring complaints, such as sticks and debris in bags, and we mention them where owners report them consistently.

What do cardinals eat?

The Cornell Lab describes Northern Cardinals as eating mainly seeds and fruit, with insects added in spring and summer. Nestlings are fed mostly insects. At feeders, cardinals favor black oil sunflower seed. In the wild they eat dogwood berries, wild grape, sedge and grass seeds, and many other seeds and fruits.

Their bill is the key. A cardinal’s thick, cone-shaped bill is built to crack hard shells. That makes sunflower and safflower easy work, while it also makes cardinals less dependent on tiny seeds such as nyjer, which suit finches better.

Cardinals are also ground and low-shrub foragers. Cornell notes they hop through low branches and forage on or near the ground, often alongside juncos, sparrows, titmice and goldfinches in winter. That tells you where to put the food: on a sturdy hopper or tray, close to cover. Our Northern Cardinal guide covers plants and nesting in more depth.

Best overall: Wagner’s Four Season Black Oil Sunflower

This bag contains one thing: black oil sunflower seed. Retail listings show a guaranteed analysis of at least 14% protein and 24% fat, and it is sold in sizes from 10 lb to 40 lb. Wagner’s says it has made bird food in the USA since 1894.

Why it suits cardinals: black oil sunflower has thinner shells and more oil than striped sunflower, so cardinals crack it quickly and get more energy per seed. Project FeederWatch calls it the preferred food of a wide variety of birds, and Cornell names it as the cardinal’s feeder favorite.

Strengths: no filler, broad appeal to chickadees, titmice, nuthatches and finches, and low cost per pound in large bags.

Drawbacks: hulls pile up under the feeder. Squirrels, grackles and House Sparrows love it too. Several owners on major retail sites report sticks and plant debris in some bags, so a quick sift before filling a tube feeder is worthwhile.

Skip it if: blackbirds or squirrels already dominate your feeder. Start with safflower instead. Our guide to black oil sunflower seed explains why it is the one seed to start with.

Best cardinal blend: Wagner’s 62032 Cardinal Blend

Wagner’s Cardinal Blend lists three ingredients: black oil sunflower, safflower and striped sunflower. The guaranteed analysis shows 14% protein and 17% fat, and it comes in a 6 lb bag. The maker suggests offering it in a platform feeder or scattered on the ground.

Why it suits cardinals: every seed in the bag is one cardinals eat. Striped sunflower has a thicker shell that small birds struggle with, which tilts the mix toward larger birds such as cardinals, jays and grosbeaks.

Strengths: no milo, millet or corn filler. Owner feedback frequently reports cardinals arriving quickly after switching to it.

Drawbacks: the 6 lb bag costs more per pound than bulk sunflower. As with Wagner’s sunflower, some owners report sticks in the bag.

Skip it if: you want the lowest cost per pound. A 25 lb bag of black oil sunflower plus a 5 lb bag of safflower gives you a similar mix for less.

Best large bag blend: Lyric Cardinal Premium Sunflower and Safflower Mix

Lyric’s Cardinal mix is over 70% sunflower, split between black oil sunflower, black striped sunflower and sunflower kernels, with safflower and buckwheat added. It is sold in 3.75 lb and 18 lb bags.

Why it suits cardinals: the high sunflower share and the safflower keep it attractive to cardinals, and the hulled kernels give smaller birds something easy to eat as well.

Strengths: the 18 lb bag lasts a busy feeder several weeks. Lyric lists grosbeaks, jays, chickadees and mockingbirds among the target species.

Drawbacks: buckwheat is less popular than sunflower, and some of it may end up on the ground. Lyric notes the recipe is adjusted as needed, so exact proportions can vary.

Skip it if: you want a blend with only sunflower and safflower.

Best for grackles and squirrels: Wagner’s 57075 Safflower Seed

This is plain safflower in a 5 lb bag. Safflower is a small, white, hard-shelled seed with a bitter taste that many squirrels and blackbirds dislike.

Why it suits cardinals: Birds and Blooms calls cardinals huge fans of safflower, and the seed also draws titmice, chickadees, house finches, grosbeaks and mourning doves. Grackles, starlings and blackbirds tend to avoid it.

Strengths: the best single tool for taking a feeder back from grackles. Cole’s, a seed maker, also describes safflower as close to sunflower in nutrition.

Drawbacks: Project FeederWatch notes most birds prefer sunflower over safflower, so total traffic can drop at first. Some squirrels learn to eat it anyway. Birds may take a week or more to accept it.

Skip it if: you have no pest problem. Sunflower draws more species. Our safflower seed guide explains how to switch.

Thinner-hulled safflower: Lyric Golden Safflower

Golden safflower is a different safflower variety. Lyric states that it has a 40% thinner hull than white safflower, with 25% more protein, 30% more fat and 15% more oil. Retail listings show a guaranteed analysis of at least 18% protein, in 5 lb and 12 lb bags.

Why it suits cardinals: the thinner hull means less work per seed and fewer hulls on the ground.

Strengths: keeps the squirrel and grackle resistance of safflower while making the seed easier to open.

Drawbacks: owner feedback is mixed. Some report birds taking it eagerly, and others report birds ignoring it in favor of white safflower. Some reviewers mention stems in bags.

Skip it if: your cardinals already eat white safflower well. There is little reason to change a food that works.

Best hot seed: Cole’s Cajun Cardinal Blend

Cole’s Cajun Cardinal Blend lists sunflower meats, safflower, food-grade liquid habanero chili peppers and safflower oil. It comes in 5, 10 and 20 lb bags.

Why it suits cardinals: it is made of the two seeds cardinals like most, and the sunflower is already shelled. The pepper coating targets mammals. Research on pain receptors has shown that birds do not respond to capsaicin the way mammals do, so cardinals eat it normally while squirrels find it unpleasant.

Strengths: a strong option when squirrels ignore safflower alone, and hulled sunflower means less waste on the ground.

Drawbacks: hot seed usually costs more per pound than plain seed. Pepper residue can irritate eyes and skin, so wear gloves.

Skip it if: a baffle would solve your squirrel problem for less. Our guide to bird food squirrels won’t eat compares hot seed with other options.

Best no-mess option: Lyric Sunflower Kernels

Lyric Sunflower Kernels are shelled sunflower seed and nothing else. Lyric describes the product as 100% edible, sold in 5 lb and 25 lb bags, and lists cardinals, grosbeaks, buntings, chickadees, finches, nuthatches and woodpeckers among the birds it draws.

Why it suits cardinals: they eat the kernel instantly without cracking a hull, and nothing is left behind.

Strengths: no hulls on the patio, no seed sprouting in flower beds, and fast feeding for shy birds that grab a seed and leave.

Drawbacks: hulled seed costs more per pound, and without a shell it spoils faster in rain. Lyric recommends feeders that protect seed from weather.

Skip it if: your feeder is an open tray with no roof. For more options, see our roundup of the best no-mess bird seed.

Is black oil sunflower or safflower better for cardinals?

Black oil sunflower wins on appeal. It draws cardinals faster and brings more species with them. Safflower wins on selectivity. It keeps cardinals, titmice and finches coming while turning away many grackles, starlings and squirrels.

A practical middle path: run one feeder with sunflower and one with safflower. If pests take over the sunflower feeder, pull it for a few weeks while the safflower feeder keeps cardinals coming.

How to switch cardinals to safflower

1. Offer safflower alone. Birds and Blooms advises against mixing it with sunflower at the start, since birds will pick out the sunflower and leave the rest.
2. Use a platform or hopper feeder. Safflower is a larger seed that suits these feeders.
3. Start with a small bag. Local birds vary, and some yards see quick results while others do not.
4. Give it at least a week. Cardinals are cautious with new foods.
5. Keep sunflower elsewhere if you like. A distant feeder with sunflower can draw pests away while cardinals learn the new seed.

What to avoid in a cardinal seed mix

Cheap mixes are often mostly filler. Project FeederWatch notes that milo is not a favorite of most birds and often goes to waste, and eastern hosts in particular should avoid mixes heavy in it. Red millet and large amounts of cracked corn tend to draw House Sparrows, cowbirds, blackbirds and squirrels rather than cardinals.

Read the ingredient list, which is ordered by weight. If sunflower or safflower is not first or second, the bag is not built for cardinals. Also skip anything with artificial color. Cardinals do not choose seed by color, and dyes add nothing.

Which feeder is best for cardinals?

Cardinals want a wide, stable place to stand. Hopper feeders with a full-length ledge and platform feeders work best. Tube feeders with short perches are usable but less comfortable for a bird this size.

Placement matters as much as the feeder. Put it 10 to 15 feet from dense shrubs or small evergreens, so cardinals can reach cover quickly, and not so close that cats can ambush from the bushes. Cardinals often visit early and late in the day, when light is low. For specific models, see our roundup of feeders to attract cardinals.

Will cardinals come to my yard?

Northern Cardinals live year-round across the eastern and central United States, south into Mexico, with separate populations in parts of the desert Southwest. The Cornell Lab notes that the species has expanded northward over the past century and that its numbers have grown since the 1960s, helped by suburban yards, edge habitat and bird feeders. If you live in New England, the Great Lakes region or southern Canada, cardinals are now common where they were once scarce.

If you live in the Pacific Northwest, the Rockies or most of California, cardinals are rare or absent, and the best seed in the world will not change that. In those regions, the same sunflower and safflower feed grosbeaks, jays and towhees instead.

Should you add mealworms or fruit for cardinals?

Seed should be the base, but a small side dish can help in some seasons. Cornell notes that cardinals feed nestlings mostly insects and eat beetles, crickets, katydids and spiders themselves in summer. A few dried or live mealworms in a dish near cover can bring adults in during nesting season. Our guide to the best dried mealworms covers the options.

In fall and winter, cardinals eat wild fruit such as dogwood berries and wild grape. Planting native fruiting shrubs does more than any feeder food, because it gives cardinals both food and the dense cover they want nearby.

Seasonal feeding for cardinals

Northern Cardinals do not migrate, so the same birds may use your feeder all year.

• Winter: high-fat food matters most. Keep sunflower or safflower available every day, especially before storms.
• Spring: males may feed females at the feeder during courtship. Add a small dish of mealworms if you like, since nestlings are fed mostly insects.
• Summer: cardinals find more natural food, and visits can drop. Keep hulled seed dry, since it spoils faster in heat and humidity.
• Fall: young cardinals, brown with dark bills, join adults at the feeder.

Common mistakes

• Buying a mix full of millet and milo. It attracts sparrows and blackbirds, not cardinals.
• Using only a small tube feeder. Cardinals prefer a wide perch or tray.
• Placing the feeder in the open. Without nearby cover, cardinals visit less.
• Mixing safflower into sunflower on day one. Birds pick out the sunflower and ignore the rest.
• Letting seed get wet. Moldy seed can sicken birds. Store seed dry in a sealed, rodent-proof container.
• Ignoring grackles. If blackbirds are the problem, see our guide to keeping starlings and grackles off feeders.
