One of the most common mistakes when hanging hummingbird feeders is placing them in direct sunlight. According to the National Audubon Society, nectar can spoil and ferment within hours when exposed to high temperatures, producing harmful bacteria and fungi that can sicken or kill hummingbirds.
Experts recommend hanging feeders in a shaded area, such as under a tree or porch overhang, to keep nectar cooler and fresher longer. This also reduces the frequency of cleaning and refilling needed, which should be done every 2-3 days in hot weather.
Another key tip is to avoid using red dye in homemade nectar. The Cornell Lab of Ornithology advises using a simple solution of 1 part white sugar to 4 parts water, boiled briefly and cooled, with no additives. Red feeders are sufficient to attract birds.
Regular cleaning with hot water and a bottle brush is essential to prevent mold growth. Never use soap or bleach, as residues can be toxic to hummingbirds.
