Adding a water feature to your built-in indoor hummingbird and bird feeder garden can be a delightful addition. Birds need water for drinking and bathing, so providing a small birdbath or a shallow water fountain will attract even more colorful bird species to your kitchen. The sound of trickling water will create a soothing ambiance, and you'll have the opportunity to observe birds splashing and preening themselves. It's a wonderful way to create a serene and tranquil atmosphere in your kitchen.
