To attract a diverse range of bird species, offer a variety of food options in your built-in indoor hummingbird and bird feeder garden. Hummingbirds are attracted to nectar, so prepare a homemade nectar solution using four parts water and one part white granulated sugar. Other bird species may be attracted to seeds, fruits, or suet. By providing a range of food options, you can enjoy the presence of different colorful birds in your kitchen.
