What Do Birds Eat? Backyard Bird Food Guide
Find out what backyard birds eat. Explore seeds, insects, suet, nectar, and favorite foods for finches, jays, nuthatches, and woodpeckers.

Birds eat seeds, nuts, insects, fruit, nectar, and other foods depending on the species and season. Finches mostly use plant foods; woodpeckers and nuthatches also find insects in trees; hummingbirds use nectar and small arthropods. A feeder can supplement this diet, but it cannot replace natural foraging habitat.
What do common backyard birds eat?
Bird | Main natural foods | A useful backyard option | What to preserve |
|---|---|---|---|
| House Finch | Seeds, buds, and fruit | Clean black-oil sunflower | Seed-bearing plants and sheltered trees |
| Cassin's Finch | Conifer seeds, buds, fruit, and some insects | Sunflower when birds are naturally present | Western evergreen and aspen woodland |
| Oregon Dark-eyed Junco | Seeds, plus insects during breeding | Small amounts of millet in a clean ground tray | Low cover and a wooded edge |
| White-breasted Nuthatch | Bark insects, seeds, and nuts | Sunflower, unsalted peanuts, or suet | Mature trees and safe cavities |
| Red-breasted Nuthatch | Insects in summer; conifer seeds in colder months | Sunflower or suet | Conifers and natural cone crops |
| Pileated Woodpecker | Carpenter ants, insect larvae, fruit, and nuts | Occasional suet | Safe decaying wood and large trees |
| Blue Jay | Acorns, nuts, seeds, fruit, and insects | Modest portions of unsalted peanuts or sunflower | Oak trees and woodland edges |
These are examples, not a menu for every bird. Check birds near you for your state and month before choosing a feeder or changing habitat.
Seeds and nuts
Black-oil sunflower is a useful general option for many finches, chickadees, cardinals, and jays. Nyjer is better suited to smaller finches. Peanuts should be fresh and unsalted. Offer modest amounts and remove leftovers rather than leaving a large food pile.
Suet and insects
Woodpeckers, nuthatches, chickadees, and some wrens may use suet, especially in colder weather. Insect-eating birds benefit most from a yard that supports insects: native plants, fewer pesticides, leaf litter, and diverse shrub layers. Mealworms can be a supplement, not the foundation of the habitat.
Fruit and nectar
Robins, waxwings, orioles, and many migrating birds use fruiting shrubs and trees. Hummingbirds use flower nectar and may visit a properly maintained nectar feeder. Use a simple sugar-water solution only as appropriate, keep it fresh, and never use dyes.
Water is part of the menu
Many birds visit a yard primarily for water. A shallow bath with a safe edge can serve seed-eaters, insect-eaters, and fruit-eaters alike. Clean water also makes a yard more useful during heat and drought.
What if birds ignore the food?
Check whether the species uses feeders at all, whether the seed is fresh, and whether the feeding spot feels exposed. A bird that searches tree bark for insects needs different habitat from one that eats seeds on the ground. Natural food, migration, weather, and nearby disturbances can also change feeder visits. Use the yard planner to work through the next change.
What should you avoid feeding birds?
Avoid moldy or spoiled food and salty or heavily processed leftovers. Bread is a poor substitute for a species-appropriate diet. Keep food dry, clean the feeding area, and do not put out more than you can maintain. A plant-based habitat can support birds even when you choose not to use a feeder.
Avoid the one-size-fits-all approach
The best food depends on the species, season, and your local habitat. Browse Explore Birds to see each species’ food profile, then check Birds Near Me to focus on birds with a seasonal signal in your state.
