Ruby-throated humming birds will be making their annual trek back from South America soon, according to Marion County Naturalist Marla Mertz. She says a few tips should be kept in mind for people interested in putting out food to help them along their journey. An easy recipe is 1 cup of sugar and 4 cups of water. She says to bring the water to a boil to sterilize it, add sugar, cool and put in your feeder.
