16. [SPECIES: northern cardinal] How to Attract More Cardinals to Your Backyard — Feeders, Seed, and Cover That Work

If you enjoy the bright red flash and cheerful presence of northern cardinals in your backyard but struggle to attract more of them consistently, you’re not alone. Many birders find cardinals to be a bit selective when it comes to food, feeders, and nearby cover. This guide will walk you through the practical steps you can take to create an inviting habitat for northern cardinals, focusing on the best feeders, seed types, and cover options that suit their habits while respecting ethical birding practices.

What It Is: Northern Cardinals and Their Preferences

Northern cardinals (Cardinalis cardinalis) are a beloved species known for their striking red plumage (males) and warm, brownish-red tones (females). They favor dense shrubby areas and edges of woodlands for both nesting and foraging. While cardinals are relatively common in much of the eastern and central United States, they can be cautious visitors to feeders, preferring well-chosen seed types and cover that allows them to feel safe from predators. Understanding these preferences is key before you invest time and money in setup.

How It Works: Attracting Cardinals Through Food, Feeders, and Cover

Step 1: Selecting the Right Seed

Cardinals prefer a variety of seeds, but some are unequivocally more attractive. Black oil sunflower seed ranks at the top because its thin shells are easy for them to crack open. They also enjoy safflower seed and cracked corn. Avoid smaller seeds like millet, which cardinals tend to ignore, and mixes heavy in milo or other fillers.

Tip: Keep feed fresh and dry. Cardinals can be sensitive to moldy or stale seed.

Step 2: Choosing Feeders That Suit Cardinal Behavior

Cardinals are ground and low-perching feeders but are territorial and can be shy around busy feeding stations.

Feeder Type	Advantages	Disadvantages	Best Situations
Tray/Platform Feeders	Allow cardinals to feed comfortably with ample space	Seeds can get wet if uncovered; attracts squirrels	Open yards with moderate seed traffic
Hopper Feeders	Large seed capacity; seeds stay dry; cardinals can perch	Bulkier, may attract various species competing	Larger yards or communal feeding stations
Tube Feeders	Seed stays clean and dry; dispenser usually for small seeds	Not ideal for cardinals since they dislike small seed ports	Use only if filled with large seeds like sunflower seed
Ground Feeding Areas	Most natural feeding method for cardinals	Attracts squirrels and may be messy; potential for disease spread	Backyard areas with natural ground cover and sparing feeding

Combine feeders according to your yard’s layout, but emphasize tray or hopper feeders filled with black oil sunflower seeds to maximize cardinal visits.

Step 3: Providing Appropriate Cover and Shelter

Cardinals seek dense shrubs and low trees to perch, feed, and hide from predators. To make your backyard inviting:

• Plant native shrubs such as dogwood, viburnum, or sumac that create dense thickets.
• Consider evergreen shrubs or conifers to provide year-round cover.
• Place feeders near such vegetative cover but not so close that predators (cats, hawks) can ambush easily.
• Incorporate brush piles or natural ground cover where cardinals can retreat if startled.

Birds like cardinals rely heavily on cover to feel secure. This decreases the chance they’ll flush (fly away) due to perceived threats, which improves your viewing experience and is better birding ethics.

When to Use These Techniques: Seasonal and Daily Considerations

• Winter: Cardinals heavily use feeders when natural food is scarce. Prioritize fresh black oil sunflower seed and maintain clear access.
• Spring and Summer: Cardinals focus on nesting and feeding fledglings insects and fruit, but seeds still supplement their diet. Keep feeders moderately stocked and maintain dense cover for nesting.
• Daily: Refill feeders early in the morning or late in the afternoon when cardinals are most actively feeding. Avoid sudden movements or noises near feeders to prevent flushing.

Common Pitfalls to Avoid

• Using the Wrong Seed Mixes: Filling feeders with blends heavy in millet or low-preference seeds will reduce cardinals’ interest.
• Placing Feeders in Open, Exposed Locations: Cardinals feel vulnerable without cover nearby and may not linger.
• Neglecting Feeder Maintenance: Moldy seeds or dirty feeders can spread disease, especially when cardinals are ground feeding.
• Overcrowding Feeders: Cardinals are aggressive feeders and may dominate, so spacing feeders and providing multiple stations reduces stress.
• Using Playback or Attractants Excessively: While that might increase sightings, it can stress birds and cause unnatural behaviors.

Summary Comparison: Best Seed and Feeder Combinations for Northern Cardinals

Seed Type	Feeder Type	Cardinal Feed Rate	Ease of Maintenance	Notes
Black Oil Sunflower	Tray / Platform Feeder	High	Moderate	Best all-around choice
Safflower	Hopper Feeder	Moderate-High	High	Slightly less preferred than sunflower; less squirrel-attractive
Cracked Corn	Ground Feeding	Moderate	Low	Use sparingly; attracts deer and other wildlife
Millet Mix	Tube Feeder	Low	High	Least attractive; avoid for cardinals

Ethical Considerations When Feeding Cardinals

• Do not use playback calls in excess to lure cardinals, as it can cause stress.
• Avoid flooding feeders with seed, which can encourage waste and excessive competition.
• Keep feeders clean to minimize disease spread.
• Never encourage cardinals to feed in open areas where predators are easily able to hunt.

By offering high-quality sunflower seeds at appropriate feeders placed near protective cover, you’ll create a welcoming backyard environment that supports both cardinals’ needs and ethical birding practices.

Frequently Asked Questions

Q: What type of seed should I avoid to attract more cardinals?
A: Avoid small seeds like millet or mixes high in filler grains; cardinals prefer larger seeds like black oil sunflower.

Q: Are tube feeders good for cardinals?
A: Generally, no. Cardinals prefer platform or hopper feeders that allow easy access to larger seeds.

Q: How close should feeders be to shrubs or cover?
A: Place feeders within 5 to 15 feet of dense cover to provide cardinals with a quick escape route but not so close that predators can hide near the feeder.
