Watch for signs of mold and mildew in the seed or on the feeder. Clean and dry your feeder if signs of mold or mildew are present. Bird baths can be enhanced with drippers and misters, which many birds love. Keep the water fresh, and clean out the birdbath on a regular basis to eliminate contamination. Orange and grapefruit halves attract orioles, jays, tanagers and flickers .
Mealworms are popular with several species.
Bluebirds especially love them. Be careful in purchasing the bags of mixed seed commonly seen in grocery stores and discount stores. Many of these mixes contain large amounts of milo and other seed that may not be popular with the birds in your area. Trash cans with a tight lid make an ideal storage container. Do not feed seed or grain that has become moldy or covered with mildew.
