Hummingbird Feeders. Hummingbirds get the energy they need to maintain their astonishing metabolism primarily from flower nectar and the sugar water they find at feeders (here's the recipe). Think of them as miniature flycatchers, and sugar is just the fuel for getting their real nourishment.
afÂ·terÂ·imÂ·age. n. A visual image that persists after the visual stimulus causing it has ceased to act. Also called photogene. (ËÉËftÉrËÉªmÉªdÊ).
There are instances in our life wherein we still continue to see images even if we stopped looking at the original picture. This occurrence is called an afterimage. This happens because of our vision. There are times when a series of lines seem to float even if they do not. This is an example of an optical illusion that our eyes seldom experience. Afterimages occur because our vision has the capacity to portray motion. Thatâs why pictures in rapid motion seem to portray action.
