Suet for Birds: A Winter Superfood That Brings Your Backyard to Life

Winter has this way of making everything slow down. The trees stand bare, the air turns sharp, and the usual sounds of morning birdsong fade into something quieter, something thinner. I always find myself wondering—what do birds even eat in this? How do they get by when the ground is frozen solid, and the bugs are nowhere to be found?

For a while, I assumed seed was enough. Black oil sunflower seeds, safflower, cracked corn—all the basics were stocked up in my feeders, and the usual suspects kept showing up. But then, the colder it got, the fewer birds I saw. Something wasn’t right.
Then, one winter, I decided to try suet for birds. I’d read about it before, knew that it was high-energy, fat-based, and essential for insect-eating birds. So, I grabbed a store-bought suet cake, slid it into a suet cage bird feeder, and waited. I wasn’t expecting much.
A few hours later, a chickadee found it. Then a nuthatch. By the next morning, a pileated woodpecker—huge, bold, striking—was clinging to the feeder, hammering away like it had been waiting for this all along. That was the moment I realized—suet wasn’t just a winter food. It was a game-changer.

When winter sets in, birds have a tough time finding food, and that’s where suet for bird feeders comes in. It’s high-energy, packed with calories, and keeps woodpeckers, chickadees, and titmice fueled through cold months. Traditional suet cakes for birds are made from the hard, white fat around a cow’s kidneys—a natural, protein-rich food that birds recognize as an energy source. Some birders still use raw suet, but most prefer suet cakes because, well… they’re a lot less messy.

That being said, not all suet blocks for birds are the same. Ever pick up a cheap suet cake, hang it up, and then notice birds barely touch it? That’s usually because of low-quality fillers like cracked corn or millet, which don’t offer much nutrition. Birds will pick around those ingredients, looking for the good stuff—pure suet, peanuts, sunflower seeds, or dried fruit. If a suet cake has corn or grain listed first, it’s probably not worth buying.

Cold weather? Great for suet. Warm weather? Not so much. When temperatures rise, regular suet cakes turn into a melted mess, sometimes spoiling before birds even finish them. That’s where no-melt suet cakes come in. They have a firmer, dough-like consistency that holds up better in the heat while still providing plenty of energy. Some birders skip suet entirely in summer, but certain birds—like woodpeckers and nuthatches—stick around year-round and will still go for it.

How you serve suet for birds can make a huge difference in which species visit. A suet cage bird feeder is the easiest setup—simple, effective, and works for most birds. But here’s the problem: starlings. Once they find your suet, they’ll devour it, leaving nothing for woodpeckers and chickadees. An upside-down suet feeder can help with that. Smaller birds have no problem clinging upside down, but starlings? Not so much.

Then there’s the squirrel problem—because, of course, they want suet too. Some people swear by hot pepper suet since birds can’t taste spice but squirrels hate it. Others go for the classic pole-and-baffle trick to keep squirrels from reaching the feeder. Either way, suet bird feeders require a little trial and error to get right.

At the end of the day, offering high-quality suet cakes for birds can bring more species to your yard and keep them well-fed throughout the seasons. Whether you’re making suet for birds homemade or buying a good store-bought blend, setting up the right feeder makes all the difference.

At first, I stuck with store-bought suet blocks for birds. They were easy, they worked, and I figured—why mess with a good thing? But the more I paid attention, the more I noticed something. Some suet cakes disappeared faster than others. Some barely got touched.

So I checked the ingredients. Some brands were packed with fillers—oats, corn, random grains that birds don’t actually care about. Others had preservatives that made me wonder how fresh they really were. That’s when I decided—if I’m feeding my birds, I want to know exactly what I’m giving them.

I started making suet for birds homemade, experimenting with different ingredients. Some mixes worked, some flopped, but once I landed on the right combination? It felt like I had unlocked some kind of secret bird-attracting formula.

Once I got into making my own suet, I never looked back. If you’ve ever wondered how to make suet for birds, this is the best recipe for suet for birds I’ve found:

1. Start with Quality Fat: I always head to my local butcher and ask for raw beef fat (commonly called suet). It’s inexpensive and feels like a hidden gem. (Please, do not use bacon grease, it is harmful to birds).

2. Render the Fat: Chopping the fat into small pieces and heating it over low heat in a pot or slow cooker fills my kitchen with an earthy, nostalgic smell. Stirring occasionally and watching the transformation reminds me of the slow, deliberate rhythms of nature. Once melted, I strain the liquid fat through cheesecloth into a clean container. It will remove any leftovers and impurities, this will allow serve suet above minus temperatures without spoiling.

3. Mix the Magic Ingredients: This is where the creativity kicks in. While the fat is warm but not hot, I add my favorite mix-ins:

– Birdseed: A staple that keeps most birds coming back for more.

– Dried Fruits: Raisins, cranberries, or chopped apricots add a sweet, natural touch.

– Nuts: Unsalted peanuts or chopped walnuts are always a hit, especially with woodpeckers.

– Cornmeal: It helps bind the mixture and adds texture.

– Dried Mealworms: I threw some into a batch once, thinking it might attract more woodpeckers. What I didn’t expect? Bluebirds showed up. I had never seen them at my feeders in winter before, but now? If I add mealworms, they come every time.

– Peanut Butter: A dollop takes the recipe to the next level, adding protein and flavor (You can melt it in a microwave, then stir it in until completely blended).

– Cayenne pepper: Birds can’t taste spice, but squirrels sure can. I started mixing a little cayenne into my suet, and just like that—the squirrels stopped stealing it. They’d sniff the feeder, flinch, and runoff. It was the best accidental discovery ever.

Consistency: It will take some time to get proper consistency, but it should be firm yet pliable (similar to a firm energy bar), so birds to easily peck at it without crumbling or melting too quickly. It is recommended to use between 50% and 70% fat and 30% to 50% percent dry mix-ins. You can test the consistency quickly by freezing a sample; if it crumbles, you need to add more fat, and if it feels too soft, you can firm it up by adding more dry ingredients.

4. Shape Your Suet: Pouring the mixture into molds (any trays you have available)—sometimes muffin tins, other times festive cookie cutters—is so much fun. I let them cool and solidify in the refrigerator or freezer, and they pop out beautifully every time.

5. Store with Care: I store the hardened cakes in airtight containers in the freezer, pulling them out as needed. There’s a little thrill every time I hang a fresh one outside, knowing it’ll soon be buzzing with activity.

I won’t lie—store-bought suet blocks for birds are convenient. No prep, no mess, just drop them into a suet cage bird feeder and you’re done. But homemade suet? That’s where the magic happens.

With homemade suet cakes, I know exactly what’s in them. No preservatives, no fillers, just high-energy ingredients that birds actually need. Plus, I can tweak the recipe—more peanuts if woodpeckers are around, extra mealworms for bluebirds, or even a holiday-shaped suet cake just for fun.

Suet is one of the best foods for backyard birds, but sometimes things don’t go as planned. You might hang up a fresh suet cake only to find it untouched for days. Or worse, it disappears overnight, leaving you wondering who ate it. If your suet bird feeder DIY setup isn’t working the way you hoped, there’s usually a simple fix.

The best way to speed things up is to place the suet feeder near an active seed feeder where birds are already gathering. This makes it more likely they’ll notice the new food source. Smearing a little peanut butter on the suet can also help get their attention. Once one bird starts eating, others will follow.

If your suet is sitting there untouched, it’s likely because birds don’t immediately recognize it as food. Unlike seeds, which most birds instinctively go for, suet can take some getting used to. Some birds are naturally cautious about new food sources and may take their time investigating.

Sometimes the problem isn’t that birds haven’t found the suet—it’s that they don’t want it. Many suet blocks for birds contain fillers like wheat, corn, or artificial binders that aren’t appealing to most species.

Check the ingredients. Birds prefer pure beef suet mixed with nuts, dried fruit, or insects. If your suet isn’t getting any takers, switching to peanut suet or a higher-quality brand can make a big difference.

Birds like woodpeckers and nuthatches are used to eating from tree trunks. If your suet cage bird feeder swings too much or is placed out in the open, birds might avoid it.

Try attaching the suet feeder to a tree trunk or a sturdy post to create a more natural feeding setup. If it’s hanging freely, put it near a shrub or tree where birds can feel safer from predators.

If birds are flocking to your seed feeders but ignoring the suet, it might be a matter of preference. Given a choice, birds often go for what’s easiest to eat.

Try cutting back on seed offerings for a few days to encourage birds to try the suet. Once they recognize it as a reliable food source, they’ll return to it even when seeds are available again.

Some days, suet seems to last forever. Other times, it’s gone in just a few hours. If suet is disappearing overnight, it’s probably not the birds eating it. Squirrels, raccoons, and even larger animals can steal suet before the birds get a chance.

One solution is to use hot pepper suet—birds don’t mind the spice, but most mammals avoid it. A caged suet feeder can also help keep squirrels and larger animals out. If raccoons are the problem, mounting the feeder on a metal pole with a baffle can help prevent them from reaching it.

Winter is the best time to offer suet, but sometimes birds don’t seem interested. If suet has been missing from your yard for a while, they may not be used to looking for it.

Keep the suet feeder out consistently so birds have a chance to find it. Some suet blends, like peanut suet or insect suet, are especially appealing in colder months. If one type isn’t working, try another.

Suet is great for winter, but in warmer weather, it can become soft, turn rancid, or grow mold before birds can finish it.

Switch to no-melt suet during hot months, and keep feeders in shaded areas to slow spoilage. If suet isn’t being eaten quickly enough, offering smaller portions can help reduce waste.

If you put up a suet feeder expecting woodpeckers, but they haven’t arrived, the problem might be the way the feeder is positioned.

Woodpeckers prefer suet that’s secured against a solid surface, rather than swinging freely. Try attaching the feeder to a tree trunk or switching to suet cylinders or log feeders, which provide a more natural feeding position.

Every winter, I go through pounds of suet. Every year, I wonder if I should cut back. And then the first cold front rolls in, the backyard goes quiet, and I see the first chickadee flit over to the empty feeder.

That’s all it takes. One look at those tiny feet clinging to the wire, one second of seeing that familiar tilt of the head—like, “Where’s my suet?”—and suddenly, I’m melting another batch, stirring in the seeds, hanging a fresh cake outside.

And just like that, winter doesn’t feel quite so empty anymore.
