Honey encourages fungal growth and may contain botulism organisms that may kill the tiny birds. Artificial sweeteners contain no real calories and may cause the hyperactive birds to starve to death. Place a hummingbird feeder where you can watch it from a window or patio. The feeder should be hung where it can be easily reached for filling and cleaning. Space multiple feeders as far apart as possible, as the birds tend to fight over feeders hung close together.
Shady spots are best - they keep the sugar solution from spoiling.
Plastic domes are available to hang over feeders to protect them from the rain. Change the syrup once a week in cooler weather and every four to five days during the summer heat. And be sure you have someone keep your feeder filled when you go on vacation, as the little birds come to depend on known sources of nectar. Keep feeders filled through October, as birds can use the food on their southward migration. To keep ants away from your feeder, apply a little petroleum jelly around the openings of the feeders and on the wire from which the feeder is suspended.
