Wild birds eat a variety of seeds, nuts, corn, millet, nectar and eggshells. Wild birds find food in the natural habitat or by visiting bird feeders. Bird watchers can attract backyard birds by offering a varied diet in bird feeders at various heights.
Food for wild birds is seasonal. In the fall and winter food becomes scarce and birds look for bird feeders. Good foods for a winter bird feeder include black sunflower seeds, crumbled corn and millet or suet.
Although most birds find plenty of food in the summer, hummingbirds benefit from having extra nectar hung in nectar feeders during the summer. In addition to food, birds also look for things like human hair and pieces of string during the nesting season and will benefit from a nesting box where these things are available.
