Regular scrubbing is required for heavily used baths. Create a small pool using a fiberglass pond or by digging a hole and lining it with a suitable rubberized or plastic liner. Bird are attracted to running water. Try hanging a dripping hose or a bucket with small hole punched in the bottom over a dish, your birdbath, or a pool. If you have the space and are willing to invest some money, hire professionals to add a large pond to your landscape.
Shelters can also protect birds from harsh weather.
Birds often take refuge in dense thickets of plants, such as brambles, hollies, and viburnums. Establishing shelter for migratory birds is an easy but vital task. Provide cover for birds by planting shrubs and evergreen trees. Use landscaping scraps to create a thick brush pile of branches or a meandering rock wall. Disperse several sources of cover throughout the entire yard.
