Do birds become dependent on backyard feeders? I would like to hang a bird feeder, but haven’t because I will likely move in a few years.

Your concern is admirable, but feeding isn’t likely to make birds dependent if you do it in moderation. Studies indicate birds that visit feeders also circulate through the surrounding area, on the hunt for natural foods in addition to backyard offerings. They quickly adapt to changes in the supply. We suggest you go ahead and feed the birds for now. When you get ready to move, reduce the amount of feed gradually— fill the feeders less often, and put out less at a time. By the time you leave, the local birds will have learned to look elsewhere.
