Suet Vs Seed Which Do Birds Prefer In Winter
Suet vs seed which do birds prefer in winter, explained by a reviewer who actually lives with the gear. No fluff, no marketing language, just what works and what doesn't.
Well, the seed industry would like you to think a tube feeder full of black-oil sunflower is the only thing a winter bird needs. But I’ve spent ten winters filling both, and my log says otherwise. I’m Mara, I run the songbird side of a county wildlife rescue, and I’ve been recording every cup of seed and suet that leaves my feeders for a decade. Here’s the short version: suet wins for clingers and insect-eaters, seed wins for the ground-feeders and finches, and you need both if you want a yard that isn’t quiet by January. The real answer is in the draw rates, and I’ve got the numbers.
| Product | Price | Why it won | Why it lost |
|---|---|---|---|
| C&S EZ Fill Suet Basket with Woodpecker Treat cakes | ~$8 for a 2-pack of cakes | Downy and hairy woodpeckers hit it within the first week of every winter log; vinyl-coated wire won’t cut feet | Cakes vanish fast in a busy yard; you’ll rebuy weekly |
| Brome Squirrel Buster Plus | ~$60 | The only feeder I’ll call squirrel-proof without a footnote; a fox squirrel spent three weeks hanging upside down off mine and never got a seed | Pricey for a tube; cardinals bounce off the cage unless you add the Cardinal Ring |
| Droll Yankees Onyx Clever Clean 18" | ~$55 | Base twists off in one motion; the only tube I’ve owned where “easy clean” is actually true | Draws a lot of house sparrows in my yard, which I don’t love |
| Pennington No-Mess Blend | ~$20 for 10 lbs | Zero hull litter under the platform; no sprouts in the garden beds | Price per pound is double the bulk sunflower hearts |
| Kaytee Black-Oil Sunflower (40-lb bag) | ~$35 | The log shows the same draw per cup as Wagner’s at half the price per pound | The 40-lb bag doesn’t fit under my kitchen sink, so it lives in the garage |
How I tested
Every feeder and seed in this article has spent at least one full season in my yard, which sits in Wisconsin where February is a real test. I track cups of seed per week in the log, and I don’t recommend anything that doesn’t survive a freeze-thaw-freeze cycle. I also weigh rehab birds in grams, so I notice when a feeder is drawing the wrong kind of crowd. The fox squirrels in my neighborhood get three weeks to test any squirrel-proof claim before I write a word about it.
Why suet wins for the clingers
The woodpeckers, nuthatches, and chickadees that hang sideways off feeders don’t want to balance on a perch. They want something to grip while they eat. My C&S EZ Fill Suet Basket with the Woodpecker Treat cakes has been the winter workhorse for six seasons. The vinyl-coated wire doesn’t cut feet like bare metal does, which matters when a downy woodpecker spends twenty minutes a day on it. I’ve logged downies and hairies on it by week one of every winter, and the nuthatches treat it like a drive-through.
The cakes themselves are the other half of the equation. The Woodpecker Treat version has more peanuts and mealworms than the standard suet cake, and the draw rate is noticeably faster. A standard cake lasts about five days in my yard. The Woodpecker Treat version lasts three. That’s the log talking, not a guess.
The seed side of the equation
Black-oil sunflower is the backbone of my winter feeding. I buy Kaytee in the 40-pound bag because it costs about half per pound what the smaller bags run, and the log shows the same draw per cup as the pricier brands. The trade-off is storage. The bag doesn’t fit under my kitchen sink, so it lives in the garage, and I refill a five-gallon bucket every week.
The Brome Squirrel Buster Plus is the tube feeder I trust with that seed. I’ve had mine for two winters, and the fox squirrel that spends his mornings testing it has never reached a single seed. The ports close under his weight every time. The one complaint I have is the cage spacing. Cardinals and other bigger birds bounce off it unless you add the Cardinal Ring, which gives them a perch to hang onto. Without it, the cardinals visit, but they don’t stay.
The cleaning reality
I’m a licensed wildlife rehabilitator, and I’ve seen what a dirty feeder does to birds. House finch eye disease and salmonella both trace back to feeders nobody took apart since fall. The Droll Yankees Onyx Clever Clean is the only tube I’ve owned where cleaning is actually easy. The base twists off in one motion, and the whole thing goes in the sink. I can take it apart, scrub it, and have it back on the pole in under ten minutes. That matters in January when my fingers are numb and I’d rather be inside.
The Brome is harder to clean. The cage comes off, but the seed ports are fiddly, and I need a small brush to get into the corners. It’s not a dealbreaker, but it’s the difference between a weekly clean and a monthly one, and I notice it in the log. The Onyx draws three cups a week in January here, and I clean it every Sunday. The Brome gets a deep clean every other week, and I can tell.
The no-mess option
If you have a deck or a HOA, the Pennington No-Mess Blend is worth the price per pound. No hulls means no sprouts under the feeder and no complaint from the neighbor. I keep a bag in the garage for when the deck needs quiet, and I’ll admit I buy the $9 small bag when I’m out and the garden beds are already full of sunflower sprouts from last winter’s hulls. The trade-off is real, and I pay it when I need it.
One thing I won’t pretend to know
I don’t track prices day to day, so I won’t pretend to know next week’s cost per pound. What I know is the cost per day over a winter. The 40-pound bag of Kaytee runs about 35 cents a day across a four-month season. The Pennington No-Mess runs closer to 60 cents a day. Both are cheaper than the $12 bag of fancy blend with milo and red millet in it, which sits in the tray uneaten and molds in the rain. Cheap seed is the most expensive seed you’ll buy.
The winter verdict
My log says the yard draws more species in a January week with both suet and seed out than with either alone. The suet brings the woodpeckers, nuthatches, and chickadees. The seed brings the juncos, cardinals, and finches. The water bath brings everything else, but that’s a different article.
Choose suet if you want woodpeckers and nuthatches and you’re okay with rebuying cakes weekly. Choose seed if you want cardinals and finches and you have a place to store a 40-pound bag. Choose both if you want a yard that isn’t quiet by February, because that’s the only way I’ve found to keep it loud. The log says so, and I’ve got ten years of it.
