The birds have come to expect a meal from your feeders and are now dependent on you. During the winter birds prefer seeds that contain a high oil content. Oil sunflower seeds, millet, and cracked corn are good choices either individually or in a commercial mix. Try these out and see if the activity increases at your bird buffet.
Water is another basic ingredient for attracting birds.
A fresh supply of water near the feeders replaced daily or if frozen, will round out the needs of your daily visitors. Here are some pointers for selecting, siting, planting and caring for houseplants. Choose plants that have healthy foliage, are free of insects and diseases, are sturdy, clean, well potted and shapely, and have new flower, leaf buds and young growth. Before purchasing a houseplant, find the place in your home where you want to put it. Identify the amount of light available and the temperature range during the day and night.
