Creating a sheltered area within your built-in indoor hummingbird and bird feeder garden is essential for attracting colorful bird species. Planting shrubs or installing birdhouses will provide birds with a safe place to rest and seek refuge from predators or harsh weather conditions. The sheltered area will also create a sense of security, encouraging birds to visit your kitchen garden more frequently. It's important to choose plants and birdhouses that are suitable for the bird species in your area.
