Hummingbird Nectar Recipe

Ingredients

  • Refined white sugar
  • Water

Directions for making safe hummingbird food:

  1. Mix 1 part sugar with 4 parts water (for example, 1 cup of sugar with 4 cups of water) until the sugar is dissolved
  2. Do not add red dye
  3. Fill your hummingbird feeders with the sugar water and place outside
  4. Extra sugar water can be stored in a refrigerator
  5. Change feeders every other day and thoroughly clean them each time to prevent harmful mold growth

Since 1970, bird populations in the U.S. and Canada have declined by 29%, or almost 3 billion birds, signaling a widespread ecological crisis. The results show tremendous losses across diverse groups of birds and habitats — from iconic songsters such as meadowlarks to long-distance migrants such as swallows and backyard birds including sparrows.

Frequently Asked Questions

Yes! You can use tap water to make your hummingbird nectar.

Always use refined white sugar (regular table sugar). Never use honey, corn syrup or raw, unprocessed sugars.

No, the water for your nectar does not need to be boiled. Just be sure to stir or shake your mixture until the sugar is fully dissolved in the water.

A part can be any type of measurement (e.g., cup, ounce, quart, etc.) but will always be equal. To calculate 1 part sugar and 4 parts water for your recipe, first choose a measurement for “one part.” Then, do some simple math:

1 x (chosen “one part” measurement) = total sugar

4 x (chosen “one part” measurement) = total water

For example, if you want to make a large batch of sugar water, you might decide that for your recipe 1 part = 2 cups.

1 x 2 cups = 2 cups sugar

4 x 2 cups = 8 cups water

So, in this example, you would mix 2 cups of sugar (1 part) with 8 cups of water (4 parts).

To make a smaller batch of sugar water, you might decide that for your recipe 1 part = ½ cup.

1 x ½ cup = ½ cup sugar

4 x ½ cup = 2 cups water

So, in this example, you would mix ½ cup of sugar (1 part) with 2 cups of water (4 parts).

Extra sugar water for your hummingbird feeder can be stored in the fridge but should be stored for no more than two weeks. If you observe any mold growing on your sugar water stored in the fridge, throw it away and make a new batch for your hummingbird feeder.

It’s recommended that feeders be changed and thoroughly cleaned every other day, but it is important that they are cleaned and refilled at least twice a week in hot weather (summer) and once a week in cooler weather (spring/fall) to prevent the growth of mold.

Hummingbirds are migratory, so the exact timing of when you should set up or take down your hummingbird feeder depends on where you live. Along the Gulf Coast and other southern parts of the U.S., feeders can be set up from mid-February to early November. In the middle latitudes, they should be placed from early-to-mid April through late October. Farther north, they can be set up from early May to late September. Visit eBird to learn more about hummingbird migration.

It’s a myth that leaving hummingbird feeders up too late in the fall will prevent the birds from migrating. Hummingbirds have an internal clock regulated by the changing day length, which lets them know when it’s time to go.

Place your feeder in the shade away from windows and areas with a lot of activity. If possible, place your feeder near trees. Hummingbirds are territorial and like to perch in nearby trees to chase away intruders at their feeding area.

Red dye or coloring isn’t necessary to attract hummingbirds and could be harmful to the birds.

Hummingbirds like flowers that produce a lot of nectar, such as bee balm, salvias, weigela, trumpet honeysuckle (and other trumpet vines) and bleeding hearts. Red, tubular flowers are especially popular with these birds.

Many nursery flowers are bred for color, longevity and size but don’t produce much nectar, but some nurseries may have sections devoted to hummingbirds. Learn more about flowers that attract hummingbirds here.
