What Birds Eat: Safe Foods (and What to Avoid)
Some birds eat seeds, some eat bugs, and some eat both-but they don’t all eat the same thing. What birds eat depends on their species, the season, and what’s available. That said, we’ve seen enough feeders raided and birdbaths filled with crumbs to know they aren’t picky when they’re hungry.
Let’s get into what they actually can and will eat.
Seeds, Grains, and Grassy Stuff
Birds do eat grass seed. They absolutely will peck it right off the ground, especially right after you’ve scattered it. They also eat oats, both whole and rolled. Cooked or raw, doesn’t matter much-though they like it dry because wet oats can clump in their throats.
They will eat oatmeal too. You can give it to them raw or cooked, but no sugar, milk, or toppings. Plain is best.
Yes, birds eat safflower seeds. Cardinals love them, as do chickadees and finches. Not all species care for safflower though-grackles and starlings usually skip it, which is a bonus if you’re trying to keep those bullies away.
Chia seeds? Birds can eat those too. They’re safe and even kind of nutritious (omega-3s, protein), but they’re tiny and get stuck in feeders. Better to mix them into suet or scatter them in dry spots.
Pumpkin seeds also make the list. Just make sure they’re unsalted and shelled if you’re putting them out for smaller birds.
Will birds eat popcorn? Yes-but it has to be plain, air-popped, and unbuttered. Salted, microwaved, or flavored popcorn isn’t safe. Don’t feed them unpopped kernels either; they’re too hard.
Nuts and Nut Butters
Birds can eat peanuts, and most of them love it. Woodpeckers, jays, titmice, even nuthatches will show up if you’ve got shelled peanuts or peanut bits in a feeder. Just no salt or seasoning.
Same goes for almonds and walnuts. Can birds eat almonds? Yes. Do birds eat walnuts? Yep. But those need to be chopped and plain. Too big and they’ll be ignored or dropped. Some birds will eat them right out of your hand, if you’re patient enough.
Peanut butter is fine too. Birds do eat peanut butter, and it’s actually a great winter energy source. Just smear it on a pine cone or mix it into suet. Natural and unsweetened is best-no xylitol or additives.
Fruit, Veggies, and Sweet Stuff
Birds can eat raisins. Soaking them in warm water makes them easier to chew, especially for younger birds. Robins and bluebirds really go for them.
Oranges are also safe. Birds can eat oranges, especially orioles, tanagers, and mockingbirds. Just slice them in half and leave them out flesh-side-up.
Can birds eat strawberries? Yes. Most soft fruits are fine-they love them. Leave the tops on too. Strawberries, blueberries, blackberries, all good.
Tomatoes are trickier. Birds do eat tomatoes, especially cherry tomatoes from garden vines. But too much can cause stomach issues because they’re acidic. It’s not dangerous in small amounts, just don’t feed them a whole bowl of cut-up tomatoes.
Bugs, Ants, and Other Protein
Birds eat ants. No doubt about it. They’ll pick them off sidewalks or snatch them from the soil. Woodpeckers and flickers love them especially. In fact, ants are a main protein source for many wild birds.
They also go after mealworms, crickets, spiders, and grubs. It depends on the bird, but insects are a normal part of many diets.
Other Common Questions
Do birds eat grass? Not exactly. They may tug on blades or nibble at them a little, but they aren’t eating it the way a cow does. They might just be pulling insects out of it.
Do birds eat cheese? Rarely. Some will peck at hard cheese crumbs, but dairy isn’t great for their digestion. Tiny bits of aged, unsalted cheese might be okay in cold months, but it shouldn’t be a regular thing.
Do birds eat oatmeal? They do, like we mentioned earlier. Cooked or dry, as long as it’s plain.
Does birds eat grass seed? Yes-same as the “do birds eat grass seed” question above. They go after it quickly.
Will birds eat popcorn? Yep, as long as it’s plain and air-popped.
Do birds eat almonds? Yes, if chopped and unsalted.
Do birds eat peanut butter? Definitely.
Do birds eat pumpkin seeds? Yes, shelled and unsalted works best.
What to Avoid
Here’s a quick table of what NOT to give birds:
| Item | Why to Avoid |
|---|---|
| Salted nuts | Salt can harm their kidneys |
| Buttered popcorn | Too greasy, contains dairy and salt |
| Moldy bread | Mold is toxic to birds |
| Sugary cereals | Too much sugar, no real nutrition |
| Chocolate | Toxic to birds (like dogs) |
| Milk | Birds can’t digest lactose |
Best Practice Tips
- Stick to unsalted, unseasoned, and plain food.
- Always chop larger items into bite-sized bits.
- Mix dry seeds with soft foods like fruits or suet.
- Clean feeders often to avoid spreading disease.
- Don’t overfeed one type of food (variety keeps them healthy).
If you’re ever unsure, just think natural. If birds would find it in the wild or it’s similar to something they might peck at outdoors, it’s probably fine in moderation. If it’s processed, salty, or sticky-skip it.
That’s pretty much the rundown. You can mix and match foods depending on season and local species. Just don’t be surprised when squirrels show up too.
