Birds will come to your yard if you feed them seeds, but seeds aren’t the only food group out there. Birds eat a lot of different things, and the foods below will help you get even more kinds of birds.
Technically, suet is the hard fat around the kidneys and loins of beef and mutton. However, most types of beef fat are also called suet and are safe for birds to eat. Suet is particularly attractive to woodpeckers, nuthatches, chickadees, jays, and starlings. Wrens, creepers, kinglets, and even cardinals and some warblers occasionally visit suet feeders. Many birds can easily digest and use animal fat as fuel. It’s a high-energy food that is especially useful when it’s cold outside.
Raw suet grows rancid quickly when temperatures are above freezing; don’t offer that except in winter. When the impurities are taken out of suet by “rendering” it, it keeps much longer, but it can still get soft in warm weather. Suet that gets too soft can cover the belly feathers, which is dangerous, especially in the spring and summer when birds are incubating because the eggs may get clogged up with tiny pores that stop the embryo from getting enough oxygen.
Suet cakes are blocks that are made from suet or a thick substitute mixed with other things like peanuts, fruits, corn meal, or even dried bugs. To avoid getting sick, it’s important to either make your own suet cakes or buy them from trustworthy sellers since corn and peanuts can hold bacteria. It may be prudent to keep suet cakes made with corn, cornmeal, or peanuts refrigerated until using.
Starlings are very fond of suet. To dissuade them, offer suet in a feeder that requires birds to feed hanging upside down. Woodpeckers, chickadees, and nuthatches will access it easily, but starlings cannot.
In winter, especially in cold climates, peanut butter is a nutritious food to offer birds. Peanut butter sold in stores is certified safe for people to eat, and it’s also safe to give to birds when it’s cold enough to keep it hard. In warmer weather it must not be kept outside long enough to become rancid or soft.
There is some concern that soft peanut butter can stick to birds’ mouths. You can add cornmeal to make it grittier, but keep in mind that both corn and peanuts are great places for bacteria and fungi to grow, so make sure peanut butter feeders are cleaned out often. Peanut oils can separate in both pure peanut butter and in mixtures. If these oils stick to a bird’s feathers while it’s nesting, they can get into the eggs and block the pores, so never give birds peanut butter mixtures that get soft or oily.
Mealworms are larvae of a flightless insect called the darkling beetle. They are a big problem in granaries, but they are safe and easy to keep in our homes as long as we keep them in plastic bins or buckets.
Many birds, even ones that don’t usually come to feeders, can get a lot of protein, calcium, and vitamins from mealworms. However, mealworms are only as healthy as the food they are fed. If you buy a lot of them, they’ll come in wads of newspaper, and they’ll eat the paper, ink and all. So make sure to remove them from the paper as quickly as possible when they arrive. It can be hard to get them out of their packaging. To keep them from getting into your home, move them from the packaging to your buckets outside or over a very large piece of white paper. This way, you can see any mealworms that get away before they get too far. They don’t have to go far to find food, but most people don’t like the idea of them living or dead in cracks in their homes.
Fill the bottom of an ice cream bucket, dishpan, or other similar bin with about an inch or two of dry oatmeal or wheat bran to keep a lot of mealworms alive. Add chunks of raw potato or apple for moisture, and then put the mealworms in. During the nesting season, especially, you can boost the levels of many nutrients by adding powdered hand-feeding bird food (the kind that is sold as a complete diet for baby parrots that were raised by hand).
Mealworms can’t get out of a plastic container like a bucket as long as there is a wall at least two or three inches high between the inside and the outside. Store them in the coolest room in your house—a basement is often a good choice—on a surface that won’t be easy to knock over.
The North American Bluebird Society website has a lot of great information about mealworms. The Sialis website has information on how to raise them.
Many birds will eat mealworms at feeders so quickly that it is only cost-effective to put out a few at a time at feeders that birds you don’t want to help can’t get to. Small window feeders made of acrylic work well. If yours has drainage holes, make sure to plug them because mealworms can fit through surprisingly small openings. Special bluebird feeders that exclude most other birds are available commercially, or plans are available here.
If you enjoy feeding birds in your backyard, you may have wondered if you can recycle bacon grease by mixing it into homemade bird food. This fat leftover from cooking bacon seems like an economical way to create suet cakes or birdseed balls for your feathered friends. But is bacon grease actually safe and healthy for wild birds?
There are a few factors to consider before placing bacon-infused treats in your yard feeders. While small amounts of bacon grease are unlikely to harm birds it does pose some potential risks. Understanding bird biology and being careful with preparation methods allows you to minimize these risks.
Potential Benefits of Bacon Grease for Birds
At first glance, reusing bacon grease in bird food seems ingenious. Here are some potential advantages:
- Provides fat and calories for energy
- Adds appealing smell to attract birds
- Makes birdseed stick together into balls
- Reuses waste fat rather than discarding
- Can be made cheaply at home
During cold months when birds require more calories, the extra fat and calories from bacon grease gives them an energy boost. The strong smell can also grab birds’ attention.
If you mix seeds with just enough grease, you can form cohesive seed balls that birds can cling to. And recycling kitchen waste into bird food allows you to be resourceful.
So in theory, bacon grease offers some utility for homemade bird foods. But a deeper look reveals some drawbacks.
Potential Downsides for Birds
The biggest risk bacon grease poses to birds is fouling their feathers, Just a small amount of grease can damage birds’ natural waterproofing and insulation
Birds spread grease onto their feathers when preening or landing on fatty surfaces. Greasy feathers then mat and separate, allowing cold water penetration.
This loss of insulation, called “waterlogging”, can lead to hypothermia and even death during winter. So avoiding direct contact with grease is crucial.
Some other potential issues with bacon grease for birds include:
- Can turn rancid and grow bacteria if left out
- Hard for birds to digest compared to plant-based oils
- High in unhealthy saturated fats
- Salt content can be harmful in excess
- Particles can clump in birds’ bills or feet
Overall, more natural oils with less processing and additives are healthier for birds. So proper precautions are necessary when using bacon grease.
Safest Methods for Using Bacon Grease
If you want to reuse bacon fat for birds, here are some tips to reduce risks:
-
Place in suet feeder cages rather than smearing. Prevents feathers from contacting grease directly.
-
Limit to small amounts as a supplement only. Should not exceed 20% of any mix.
-
Store any excess grease in the refrigerator or freezer. Prevents rancidity.
-
Avoid adding to liquid bird baths. Fats make slick surfaces that drown birds.
-
Mix with seeds rather than coat seeds. Minimizes amount needed to form balls.
-
Strain out any solid bits through cheesecloth first. Reduces gritty texture issues.
-
Never cook and add to bird baths. Hot grease can severely burn birds.
Following these precautions minimizes potential feather fouling and illness from too much grease. But many rehabbers still recommend against using any bacon grease at all.
Healthier Alternatives to Bacon Grease
For the healthiest and safest suet feeders and seed balls, experts suggest using vegetable-based fats instead.
Here are some better options than bacon grease:
-
Pure raw suet – High in healthy CLA fats. Won’t smear onto feathers.
-
Peanut or almond butter – Rich in monounsaturated fats birds can digest easily.
-
Flax or hemp seed oil – Provides beneficial omega-3 fatty acids.
-
Rice bran – High fat content with antioxidants. Will solidify when cool.
-
Coconut oil – Naturally solid at room temperature. Resists rancidity.
These plant-based alternatives offer great energy for birds without the same mess and digestion issues as animal fats like bacon grease. They can be blended with seeds, berries, and nuts to create suet cakes that appeal to a variety of birds.
Questions About Bacon Grease for Birds
Before using bacon grease for backyard birds, some common questions include:
Is bacon grease healthy for birds?
In very small amounts, bacon grease won’t immediately harm birds. But it provides minimal nutrition compared to more natural fats and oils.
Can you mix bacon grease with bird seed?
Bacon grease can help seeds stick together. But only use minimal amounts. Excess grease can smear onto feathers from preening.
Is bacon grease good in bird feeders?
Only if inside specialty suet cages that prevent direct contact with the fat. Open feeders allow birds to land in grease.
Can you put bacon grease on a bird feeder pole?
Never spread bacon grease loosely on poles or trees. Birds will get it on their feathers leading to waterlogging.
Is bacon grease better than vegetable oil for birds?
No, plant-based oils higher in polyunsaturated fats digest more easily and pose less feather fouling risks.
The Bottom Line
While the strong smell of bacon grease initially attracts birds, the potential drawbacks make it a poor choice compared to more natural plant-based fats. Limited use in suet feeder cakes is unlikely to harm birds, but healthier alternatives exist.
If reusing bacon fat dumped from cooking, take steps to minimize contact with birds’ feathers. Even small amounts of grease can have detrimental impacts on their water resistance and temperature regulation. Overall, natural vegetable oils and plant fats make much healthier additions to bird diets.

Fruits and fruit seeds
A lot of people in the tropics put out fruit for birds, which brings in a lot of tanagers and other birds that people in North America don’t usually think of as “feeder birds.” But robins, thrushes, waxwings, bluebirds, mockingbirds, catbirds, and tanagers can sometimes be drawn to bird feeders with fruit, even in the north. Because not many people in the US or Canada put fruit on feeders, these species haven’t eaten from feeders before, so it can be hard to get them close enough to understand what you’re trying to do. Fresh berries; chunks of fresh apples, melons, or grapes; or frozen berries, are excellent choices. Raisins or currants that have been softened by soaking in water may also be good. Orange halves are particularly attractive during spring migration, especially to orioles.
Providing fruits can cause some serious problems. It spoils quickly, so feeders must be emptied and cleaned very frequently. Offering fruit in a plastic cereal bowl makes this an easier task. Fruit unfortunately attracts ants and wasps in the summer. Luckily, there’s no reason to feed fruit in the summer and fall when there is so much fresh fruit around naturally.
Pumpkin seeds and other squash or melon seeds can be extremely attractive for birds. Dry them out in the oven or on a flat surface, and then chop them up in a food processor. This will make them easier for smaller birds to eat.
Orioles, catbirds, and sometimes Cape May Warblers can be enticed to visit feeders offering jelly. Make sure you only give out very small amounts at a time because the jelly gets very sticky and small birds can get stuck in it. Also, jelly has much higher sugar concentrations than any natural food. Adult birds probably shouldn’t avoid adding extra food to their diets when there isn’t enough food because of unusually cold weather in the spring, or in small amounts the rest of the year. Adult orioles and other birds sometimes stop by jelly for a quick snack while they look for bugs to feed their young in the summer. This won’t hurt them.
Eggshells are an excellent source of grit and calcium, but chicken eggs may harbor the salmonella bacteria. When hard-boiled eggs are cooked, the shells become germ-free. If you have eggshells that weren’t cooked, bake them at 250 degrees Fahrenheit for 20 minutes, let them cool, and then break them up into pieces smaller than a dime. When you’re not giving out seeds, put eggshells on the ground, in a dish, or on a low platform feeder.
Not recommended. It might seem like a good idea to avoid throwing away food by putting it out for birds to eat, but it’s not always a good idea. The food could go bad and be bad for the birds, and it’s likely to attract European Starlings, House Sparrows, or even worse animals like rats, mice, and raccoons.
Not recommended. Bacon drippings are animal fat just like suet, and many birds will eat it. But almost always, nitrosamines, which are formed from some of the preservatives used in bacon and are known to cause cancer, can be found in bacon. In particular, the very high cooking temperatures used to fry bacon are conducive to nitrosamine formation. In conclusion, bacon and bacon fat are too harmful to birds’ long-term health to be used, even though birds love them.
MAKE YOUR OWN BIRD SUET WITH BACON GREASE
Can birds eat bacon grease?
Kenn and Kimberly: We know it seems as if bacon grease should be OK, since it’s animal fat just like beef suet. But the preservatives in bacon contain carcinogenic compounds that are harmful to birds. When it comes to bread, it’s sort of like junk food for birds—it offers very little nutritional value for them.
Can you use bacon grease in bird suet?
Another potential risk of using bacon grease in bird suet is the high salt content. Commercial bacon often contains unhealthy amounts of salt and preservatives, which can be dangerous for birds if ingested in large amounts. This can lead to dehydration and other health problems.
Can birds eat bacon drippings?
While lard is a safe alternative to rendered suet, avoid using bacon drippings. The chemical preservatives in commercial bacon become more concentrated once cooked. While this doesn’t pose a health threat to humans, it can be harmful to birds. Bread and table scraps should be avoided, too. What can birds eat from the kitchen?
What is a good substitute for bacon fat?
Peanut butter and pure lard are also healthy substitutes for bacon fat. When making suet, start with equal parts lard and peanut butter. Add safe ingredients such as dried fruit, rolled oats, birdseed, cornmeal and flour. Avoid bread, sugar, leftovers, meat, bacon fat and salted nuts.
How long does it take to make peanut butter & bacon grease?
It won’t take more than 10 to 15 seconds. Pour the peanut butter and bacon grease mixture over the dry ingredients placed inside a large mixing bowl. Stir all the ingredients properly until they’re thoroughly combined. Add suet to the paper cups one by one. You can also use a non-stick spray before adding suet to containers.
What kind of fat does a bird eat?
True suet, which is the fat around the loin of a cow, is the safest and most nutritious fat for birds. Birds love suet because it provides them with the energy they need to survive in cold weather. Suet is high in protein and fat, which are essential for maintaining body heat and staying warm.
