Shaped like a classic canning jar, the Mason Jar Glass Hummingbird Feeder brings a familiar look to the backyard feeding station. Clean hummingbird feeders weekly to keep the nectar fresh and the birds healthy. In hot summer weather, clean and refill the feeder every three days. We make a larger batch of nectar and keep it in the refrigerator between refills, adding only around one cup at a time. Mix four cups of water with one cup of white sugar until the sugar is totally dissolved.
