Summary of foods commonly eaten by birds in American gardens

The American garden is home to a wide variety of bird species, each with distinct dietary preferences. These primarily include seeds and grains, insects, fruits, meat, and other categories. Below is a summary of some common foods:
Seeds and grains
Sunflower seeds: These include shelled black oil sunflower seeds and shelled sunflower seed kernels, which are a favorite food for many birds, such as Cardinals, Grosbeaks, Sparrows, and Finches.
Millet: Common varieties include white millet and red millet, which are nutrient-rich and easily digestible by birds. House Finches and other birds often consume them.
Oats, corn, and barley: These grain-based foods are also a food source for backyard birds. American Robins and other birds consume them.
Sesame seeds: Rich in oil, sesame seeds are a high-calorie food source for some small finches, helping them maintain body temperature and energy during cold seasons.
Insects
Beetles: Including various small beetles, these are rich in protein and fat, serving as an important food source for many birds. Downy Woodpeckers, for example, search for beetles on tree trunks and the ground to eat.
Ants: Ants are abundant and easy to obtain, making them a common food source for insectivorous birds. For example, birds in the Turdidae family consume ants.
Moth and butterfly larvae: These larvae are an important food source for many birds during the breeding season, as they are rich in protein and help young birds grow and develop quickly. Birds like warblers feed on them.
Mosquitoes and flies: These insects have weak flying abilities and are abundant in numbers, making them one of the primary food sources for insectivorous birds such as the American swallow.
Fruits
Grapes: Rich in water and sugar, grapes are a favorite food for some birds, such as mockingbirds.
Apples: When cut into small pieces, apples attract birds like American Robins to feed.
Berries: Including blueberries, blackberries, strawberries, and cranberries, berries are a favorite food for many birds, especially in autumn and winter when other food sources are scarce. Birds like Cedar Waxwings feed on berries.
Meat and other categories
Peanuts: Rich in protein and fat, they attract birds like Blue Jays and Nuthatches.
Mealworms: These protein-rich insects are favored by many birds, especially in winter when insects are scarce, serving as an excellent protein source. For example, House Finches consume mealworms in winter.
Suet: Made from animal fat, it is typically mixed with other foods and formed into blocks. It serves as an important energy source for birds like Woodpeckers and Chickadees during winter.
Nectar: Some birds, such as Ruby-throated Hummingbirds, rely on nectar as their primary food source, feeding on the nectar of various flowers.
