Instead of tossing those eggshells in the trash, feed them to your birds. Rinse in plain water and bake at 250 degrees for 30 minutes. Allow to cool, then crush shells into small pieces and scatter on a deck, patio, or driveway. Fruit is another welcome treat and is particularly attractive to warblers and orioles. Slice oranges in half and place cut side up on a raised platform feeder. To keep squirrels away, be sure the fruit feeder is not too close to trees or roof overhangs and is at least four feet off the ground.
Make sure your bird feed is fresh each season, since old seed stored in the basement or the garage can get moldy and contain harmful toxins and bacteria. When you buy seed in bulk, store in a clean, waterproof and rodent-proof container with a secure lid to keep out mice, squirrels, and other rodents. Make a scoop by cutting off the top of a plastic milk jug, and use a funnel to make it easy to refill feeders.
