It is a common misunderstanding that seeds are a sufficient diet for companion birds. After all, wild bird feeders are filled with seeds, right? However, while wild birds enjoy the seeds people provide, they also eat a wide variety of other foods, including plants, insects, nectar, and, for some species, other small animals.
