Usually a lot tackier than a normal bird feeder, this is a glaring red plastic doohicky with a glass tube and four flower-shaped recepticles that you hang from your eave. You fill the glass with sugar water, and the hummers suck it out through the flowers.

Tacky as it may be, hummingbirds love them, and if you have any in your area, they'll soon come around. The bright red plastic is a requirement, since hummingbirds are naturally attracted to the color.

Hang it in the sun, so that you can see the iridescent color of the birds as they feed.
