Bird food consists of a variety of ingredients designed to meet the nutritional needs of different bird species. Common types include seeds (sunflower, millet, and safflower), nuts, fruits, and grains. Wild bird food mixes often feature a combination of seeds to attract various species, while specialty foods like suet provide high-fat content for energy, especially in cold weather. For pet birds, pellets are a common choice, providing a balanced diet with vitamins and minerals. Fresh fruits, vegetables, and occasional treats like boiled eggs are also beneficial. Proper bird food supports health, energy, and longevity, promoting active, thriving birds.
