A hummingbird feeder is a specially designed container that provides nectar for hummingbirds. These feeders typically have a bright color, often red, to attract the birds. They are filled with a sugar-water solution, mimicking the natural nectar found in flowers. Most feeders have feeding ports where the birds can access the liquid. To maintain a hummingbird feeder, it is important to clean it regularly to prevent mold and bacteria growth. The sugar-water mixture should be changed every few days, especially in warm weather. Placing the feeder in a shaded area can help keep the nectar fresh longer.
