Hummingbird feeders: To alert hummingbirds of a new feeder, surround it with red or yellow artificial flowers or ribbons. These are the colors that their eyes pick up. After awhile you can take them down and the hummingbirds will remember where the feeder is. (This hasn't actually worked for the last two days, but I still have high hopes).
