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.
Should You Use Bacon Grease for Bird Feed? The Potential Risks
If you enjoy feeding the birds in your backyard, you may have wondered if you can add bacon grease to homemade bird suet or feeders. This savory kitchen leftover seems like it would make a tasty treat. However, most bird experts advise against using bacon fat for several important reasons.
In this article, we’ll explore the potential risks of bacon grease for birds and better alternatives you can use instead.
Why Bacon Grease Can Be Harmful for Birds
At first glance, reused bacon fat may appear to be an ideal ingredient for energy-packed bird feed. However, the high salt content and chemical preservatives found in most commercial bacons could cause health issues when concentrated and fed to birds.
Here’s a closer look at the specific concerns:
-
High sodium content – Most supermarket bacon contains a lot of added sodium from curing salts. While the occasional bit won’t harm birds, regularly concentrated doses via grease could lead to sodium toxicity.
-
Nitrates/nitrites – These chemical preservatives keep bacon shelf-stable. But they may be carcinogenic or toxic for birds when their intake is concentrated through rendered grease.
-
Other potential additives – Bacon may also contain flavorings, corn syrup, and anti-clumping agents that become more concentrated in leftover grease. The effects of these additives on birds are unknown.
-
Rancidity – After long storage, bacon grease can go rancid from oxidization and free radicals. Consuming rancid fats can make birds ill.
While not definitively proven toxic, most wildlife rehabilitators and ornithologists warn that the potential risks of bacon grease for birds outweigh any benefits. It’s better to stick with known bird-safe fats.
Healthier Alternatives to Bacon Fat for Birds
When making your own bird suet or adding fats to feeders, use one of these safer alternatives instead of bacon drippings:
-
Beef suet – Suet is the fat around the kidneys of cattle. Rendered beef suet offers an excellent source of energy and calories for birds. Purchase commercially or render your own.
-
Lard – Pure, fresh lard from pork fat provides a creamy alternative to suet with a similar nutrition profile. Make sure it isn’t hydrogenated.
-
Peanut butter – When mixed half and half with lard, all-natural peanut butter adds flavor and protein to DIY bird suet recipes.
-
Vegetable shortening – While not as nutritious as animal fats, shortening offers similar calories. Opt for a non-hydrogenated product.
-
Coconut oil – With a pleasing mild flavor, coconut oil remains solid in cool weather and provides digestible fat for birds.
-
Nuts – Grind or chop nuts finely before adding to suet or feeders. Choose unsalted and avoid molds.
-
Seeds – Black oil sunflower, millet, flax, and chia seeds boost nutrition and calories. Grind first for suet cakes.
Avoid using rendered bacon or ham fat, as well as old cooking grease, which can turn rancid. With healthier animal-based and plant fats, you can give birds needed energy during cold months minus the risks of bacon grease.
Pro Tips for Making Bacon Grease-Free Suet
If you want to whip up homemade suet cakes, dough balls, or other DIY bird feed, here are some useful tips:
-
Start with a 50/50 mix of lard and peanut butter for an optimal fat and protein balance.
-
Mix in additional ingredients like birdseed, oats, cornmeal, raisins, dried fruit, etc. to add nutrition and appeal.
-
Add just a touch of flour if the suet won’t hold together. Avoid using breads which mold quickly.
-
Use cookie cutters, muffin tins, or molds to shape suet into fun blocks or cakes.
-
Refrigerate for at least 2 hours to allow suet to firm up before placing outside.
-
Store any extra homemade suet in the freezer in an airtight container for 2-3 months.
Follow recipes specifically formulated for wild birds. Avoid anything containing seasoned salts, spices, chocolate, or sweets as well. Offer suet in fine mesh bags or feeders designed to keep it intact.
The Bottom Line: Bacon Grease Has No Place in Bird Feed
It can be tempting to find creative uses for bacon fat leftover from cooking. However, the potential health risks mean it should stay out of bird feeders. With so many nutritious animal- and plant-based alternatives readily available, there’s no reason to take a chance on bacon grease.
By using proper rendered fats along with seeds, nuts, and grains, you can whip up suet that gives birds energy and nutrition without any worries. Dispose of bacon drippings safely and look to beef suet, lard, plant oils, and other bird-friendly ingredients to make your own suet cakes or infused feed. Your feathered visitors will reward you with lively activity and songs all season long.
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.

FAQ
What fats are safe for birds?
Can you make bird suet from bacon fat?
Is meat grease good for birds?
Is lard safe for birds?
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.
