If you live in an area where mornings are cool or cold, use feeders without perches, or bring in the feeders overnight so the water will be warm in the morning. When hummers sit and eat very cold sugar water, they may become hypothermic. The work of hovering heats their muscles preventing this. Clean your feeder often to prevent bacteria and fungus from growing in the sugar water, and to prevent the water from fermenting. Make your sugar water mixture from 1/4 cup sugar and 1 cup water. Don't use food coloring--your feeder should have red areas to attract the hummers.
You can also provide fruit flies by setting out a mesh bag (such as onions are sold in) filled with bits of banana and melon.
