Water is an essential element for attracting birds. By adding water to your offering along with a food source, you'll attract a larger variety of birds including birds that don't eat seed such as the popular bluebird, swallow and warbler. Birds will seek out a water source in a variety of ways: rivers, streams, ponds, puddles and even raindrops. Provide them fresh, clean water in your backyard and they may never have to go elsewhere again! Keep water fresh by changing the water every few days. Clean waterer every two weeks with a mild soap and water solution. Be sure to rinse thoroughly.
