Your bird habitat should be made up of plants native to your region. The reason for this is two-fold: local birds are accustomed to local plants and the plants will thrive in their natural habitat. Native plant species are adapted to local rainfall amounts and other weather patterns, as well as soil type. They require less maintenance, less assistance from chemical fertilizers and less watering, which makes it easier on you and the environment.
Birds will flock to your habitat if they are comfortable with the plants there. Birds recognize regional trees and shrubs as sources of food and shelter from predators. Choose plants that produce seeds, berries and nuts.
If you're not sure which plants are best for attracting birds in your region, consult a local nursery or the friendly associates at your local True Value hardware store.
