This December I noticed a neighbors front tree was sporting a brand new hummingbird feeder. (complete with solidly frozen red nectar). When folks come in the store and tell me they put out a hummingbird feeder and don't get hummers I always ask "How often do you change your nectar?". Often the reply is "Oh, you mean you're suppossed to CHANGE it?" or "once a month". Bonnie Ott
