  Bird feeders are made from a variety of materials. You can buy disposable plastic bag feeders; feeders made of cloth, nylon, vinyl and metal netting; clear, lexan, colored and PVC plastic tubes; ceramic and terra cotta; redwood, western cedar, birch, pine and plywood; sheet metal and aluminized steel; glass tubes and bottles. Terra Cotta feeder How long a feeder lasts depends on how well you maintain it, the effects of weather, and whether squirrels can get to it. Water can get into any feeder regardless of how carefully you protect it. Cloth, vinyl, nylon and metal netting feeders are inexpensive, but they do not protect your seed from spoiling in damp or wet weather. Improve them by adding a plastic dome. Most wood, plastic, ceramic and solid metal feeders keep seed dry, but water can get into the feeding portals. Look for feeders with drainage holes in the bottoms of both the feeder hopper and the seed tray. Even bowl-type feeders and trays with drainage holes will clog with seed and bird droppings that can mix with rainwater and be unhealthy for any animal. Look for shallow plate-like seed trays to catch dropped seeds while allowing spent seed shells to blow away. When you feed birds, expect bird droppings and a leftover food mess. While you do not have to wash the feeder daily, you should clean it at least every few weeks. Diseases like salmonella can grow in moldy, wet seed and bird droppings in your feeder tray and on the ground below. Move your feeder a few feet each season to give the ground underneath time to assimilate the seed debris and bird droppings. The maintenance required to keep your feeder clean varies according to the type of feeder. A thistle feeder for goldfinches should be cleaned about once a month depending on how often it rains. Feeding hummingbirds requires cleaning at the very least weekly, but preferably two or three times a week. Sunflower and suet feeders need to be cleaned only once a month. Plastic, ceramic and glass feeders are easy to clean. Wash them in a bucket of hot, soapy water fortified with a capful or two of chlorine bleach. Use the same regimen with wood feeders, but substitute another disinfectant for the bleach so your wood won’t fade. |
