What Bird Seed Starlings Don’t Like and What to Use Instead

Safflower seed and nyjer (thistle) are the two seeds starlings consistently avoid or struggle with most. Peanuts in the shell also deter them because starlings can't crack the hard outer hull. If you switch your feeder today to safflower only, you'll likely see a noticeable drop in starling visits within a few days, while cardinals, chickadees, and nuthatches keep coming. That's the core answer. Everything below helps you build on it.

Seeds and foods starlings avoid (and why)

Starlings are soft-billed birds. Their bills are built for probing and scooping, not cracking hard seeds. That physical limitation is the reason certain seeds work as a deterrent, not just a matter of taste. The Alaska Department of Fish and Game recommends filling feeders with striped sunflower, safflower, peanuts in the shell, and nyjer/thistle, describing these as seeds that either can't be eaten by starlings or are generally unappealing to them.

It's worth noting that 'not like' means slightly different things depending on the seed. If you're also dealing with crows, you'll want to use a seed they don't prefer what bird seed do crows not like. With nyjer, it's mostly an access problem: the ports on a proper thistle feeder are too small and the seeds too fine for starlings to feed efficiently. With safflower, it's more about palatability. Maryland DNR specifically lists safflower as a seed that feeder hogs like grackles and starlings tend to avoid. There's a regional caveat though: in some areas, starlings have apparently acquired a taste for safflower over time, so if your flock is particularly persistent, safflower alone may not be a complete fix.

What to stop using right away

Most cheap grocery-store or big-box birdseed mixes are essentially a starling magnet. They're typically loaded with cracked corn, white millet, milo, and sometimes shelled sunflower chips, which together hit nearly every item on the starling's preferred menu. If you're using a general 'wild bird mix,' that's almost certainly the first thing to swap out.

• Cracked corn: one of the top starling attractants and also the seed most vulnerable to aflatoxin contamination, especially when it gets wet
• Shelled sunflower chips or kernels: soft, calorie-rich, and easy for starlings to swallow whole
• White millet: a soft seed starlings eat readily, especially on platform or ground feeders
• Milo / sorghum: commonly used as filler in cheap mixes; attracts starlings, grackles, and pigeons
• Suet cakes containing corn, peanut butter, or mixed nuts: these are a particular problem in winter
• Mealworms (live or dried): almost irresistible to starlings
• Bread, kitchen scraps, or any human food: avoid entirely

The mix problem also creates a mess issue. When you put out a mixed seed blend, the birds you actually want, like cardinals or finches, often toss aside the millet and corn to get to the sunflower. That discarded seed piles up on the ground below your feeder and becomes a prime food source for starlings, grackles, sparrows, and rodents. Switching to a single-seed approach (safflower or nyjer) largely eliminates this secondary feeding problem.

How to switch your seed safely today

You don't need to do a dramatic overnight overhaul. A gradual switch over 5 to 7 days reduces the risk of confusing your regulars and lets you see which birds adjust to the new seed. Here's a practical way to do it:

1. Empty and clean your feeder before making any switch (see the cleaning section below). Residue from old seed can harbor mold or pests that mask whether your new seed is working.
2. Start with a 50/50 blend of your current seed and safflower. Fill the feeder and observe over 2 to 3 days. You should see starling visits start to decline while other species continue feeding.
3. Move to 100% safflower or nyjer after 3 to 5 days. Buy a small 5 lb bag first to test before committing to a larger quantity.
4. If you have a suet feeder, replace corn-heavy or nut-heavy suet with plain suet or suet with hot pepper added (more on that below). Woodpeckers love plain suet but starlings strongly prefer the enriched kinds.
5. Remove any platform or ground feeders temporarily. Starlings, like grackles and pigeons, are ground and platform feeders by nature. Eliminating those feeding surfaces takes away a major advantage they have over other birds.
6. Watch for 7 to 10 days. If starlings are still coming heavily, the issue may be feeder design rather than seed choice. Move to the feeder section below.

A note on hot pepper seed

Hot pepper (capsaicin)-coated seed or suet is sometimes sold as a starling deterrent. Birds don't have the receptors that make capsaicin feel hot, so your target birds aren't bothered by it. Starlings and other mammals (squirrels, rodents) are deterred. It's a reasonable option to add alongside safflower if you're dealing with a stubborn flock, though it costs more and needs to be stored carefully so the coating doesn't degrade.

Feeder designs that work with your seed choice

Even the right seed in the wrong feeder can attract starlings. Starlings are bulky, bold birds that do best on open platform feeders, wide-ledge tube feeders, and standard suet cages. Switching the feeder design alongside your seed gives you a much stronger result.

• Caged tube feeders: A wire cage surrounds the feeder with openings large enough for small songbirds (chickadees, finches, nuthatches) but too small for starlings. These are one of the most effective structural barriers. Alaska DFG specifically recommends this design for starling exclusion.
• Weight-sensitive feeders: These have perches that close the feeding ports when a bird over a certain weight lands. Set the threshold to allow cardinals and finches but exclude the heavier starling (which typically weighs 2.5 to 3.5 oz). Most adjustable models let you dial in the exact weight limit.
• Upside-down suet feeders: Woodpeckers are comfortable feeding hanging upside down; starlings are not. An inverted suet feeder dramatically reduces starling access to suet without eliminating woodpecker visits. Fill with plain suet, not corn-enriched.
• Nyjer sock or thistle tube feeders: The small ports and fine seed naturally exclude starlings. Use a tube with ports no larger than 1/8 inch for best results.
• Avoid: open platform feeders, wide-tray feeders, and any feeder with a large open landing area. These are essentially designed for the kind of bold, social feeding that starlings thrive on.

Placement matters too. Starlings tend to prefer feeders in open, visible areas where the whole flock can land and feed together. Moving a feeder closer to shrub cover or under a tree canopy can subtly reduce starling comfort while your target songbirds, which are more comfortable near cover, keep visiting.

Keeping seed dry to avoid bigger problems

Wet or clumped seed is more attractive to pests and creates a whole secondary problem: mold. Starlings, like grackles, pigeons, and sparrows, are opportunistic feeders. Those same kinds of seed deterrents can also help answer what bird seed pigeons do not eat pigeons not eat. If wet or sprouted seed is sitting in or below your feeder, it's a second invitation even after you've switched to a seed they'd normally avoid. Staying on top of seed moisture is a non-negotiable part of this fix.

• Check seed moisture every 2 to 3 days in summer and rainy periods. If seed is clumping, sticky, or darker than normal, remove and discard it immediately.
• Never refill a feeder on top of old or damp seed. Even a small amount of moldy seed at the bottom of a tube feeder contaminates fresh seed added on top.
• Buy seed in quantities you'll use within 1 to 2 weeks. A 5 lb bag of safflower used quickly is safer than a 25 lb bag sitting in a garage for months.
• Store seed in a sealed, airtight container, ideally metal to deter rodents, in a cool and dry location. Keep it off concrete floors where moisture can wick up through the container.
• Corn especially: if you're still using any corn in a mix, know that it's the seed most susceptible to aflatoxin contamination. Aflatoxins can be present even when there's no visible mold and are extremely toxic at low levels. Switching away from corn entirely removes this risk.
• In hot, humid climates (the Southeast and Gulf Coast especially), clean feeders every 3 to 5 days in summer. Seed can go bad in under a week.

Cleaning your feeder the right way

A dirty feeder undermines everything else. Disease, mold, and old seed residue attract problem birds and can harm your target species. Here's the cleaning process recommended by Cornell Lab's Project FeederWatch and Audubon:

1. Remove all old seed and debris before cleaning. Dump, shake out, or use a brush to clear everything out. Don't skip this step: cleaning solution can't penetrate through a layer of crusted seed.
2. Prepare a 10% bleach solution: 1 part bleach to 9 parts water. This is the standard recommendation from both Audubon and Cornell-affiliated sources for feeder disinfection.
3. Soak the feeder in the solution for 2 to 3 minutes, then scrub all surfaces with a bottle brush or old toothbrush. Pay attention to seams, perch holes, and the base where moisture collects.
4. Rinse thoroughly with clean water. Bleach residue can harm birds, so rinse until there's no detectable smell.
5. Air-dry completely before refilling. This is the step most people skip and it matters most. A damp feeder creates the exact conditions mold needs to start growing within 24 to 48 hours.
6. Clean frequency: every 1 to 2 weeks in cool dry weather, every 3 to 5 days in hot or humid weather, and immediately any time you see black residue, mold, or sick birds near the feeder.

Ongoing maintenance to stop starlings from coming back

The seed switch and feeder change will reduce starling visits significantly, but ongoing habits are what keep them from returning. Starlings are persistent and social. If they find food, they'll be back the next day with the whole flock. The goal is to make your yard consistently unrewarding for them.

• Clean up spilled seed on the ground every 1 to 2 days. Even safflower, which starlings avoid in a feeder, can attract them on the ground when they're hungry enough. A leaf blower or stiff broom takes 2 minutes.
• Don't leave feeders full overnight if you're seeing heavy starling activity. Starlings are daytime feeders, so this won't affect your songbird visitors much, and an empty or near-empty feeder at dusk gives the flock less reason to return at dawn.
• Dispose of old or uneaten seed in the trash, not on the ground. Dumping old seed below a tree or in a garden bed is a direct invitation for ground-feeding problem birds.
• Monitor after any mix change. Give each change 7 to 10 days before concluding it's not working. Starling flocks can be persistent for a week before moving on to easier food sources.
• Watch for pattern changes by season. Starlings tend to be worst in late fall and winter when food is scarce and flocks are larger. You may need to tighten up your feeder setup more in December through February than in summer.
• If starlings are still a problem after switching seed and feeder design, consider taking feeders down entirely for 1 to 2 weeks. The resident flock often moves on, and your songbird regulars typically return within a day or two of feeders going back up.

How this compares to other problem birds

The seed choices that deter starlings overlap quite a bit with what deters grackles and pigeons. Safflower, for instance, is also disliked by grackles and most pigeons, so switching to it often helps with more than one problem at once. Sparrows are a different case: they actually eat safflower and nyjer, so those seeds don't serve as a sparrow deterrent the way they do for starlings. If your feeder problem involves multiple species, it's worth identifying which birds are causing the most disruption before choosing your seed strategy, since the fixes are similar but not identical across species.
