How to Make Hummingbird Nectar (4:1 Recipe)

You do not need to buy hummingbird nectar. Here is how to make hummingbird nectar at home: stir one part refined white sugar into four parts water until the sugar is fully dissolved, let the sugar water cool to room temperature, and pour it into a clean feeder. For a single small feeder, that is 1/4 cup of sugar in 1 cup of water. Add nothing else: no honey, no red dye, no other sweetener.

That recipe is not ours. It is the one published by the National Audubon Society, Smithsonian’s National Zoo, Penn State Extension, and the Texas Parks and Wildlife Department (TPWD). All four give the same proportion of sugar to water, and none adds a third ingredient. They split on one point, whether to boil the water, and we lay out both positions below.

This guide covers making sugar water for backyard feeders. It is not advice on caring for sick or injured birds; if you find one, contact a licensed wildlife rehabilitator or your state wildlife agency.

Hummingbird Nectar Recipe at a Glance

This homemade recipe scales to any batch size because the ratio is by volume: one part sugar, four parts water. The National Zoo explains that a part can be any measurement, such as a cup, an ounce, or a quart, as long as both parts use the same one. You will also see the recipe written as 4:1, meaning four parts water to one part sugar. It is the same mix.

What you need:

• Refined white sugar. The National Zoo calls it regular table sugar and says to always use it.
• Water. The National Zoo says tap water is fine.
• One measuring cup or scoop, used for both the sugar and the water.
• A spoon, plus a pot or kettle if you plan to heat the water.
• A clean jar with a lid if you are making extra to keep in the refrigerator.

How to Make Hummingbird Nectar, Step by Step

1. Measure one part sugar and four parts water. For 1/4 cup of sugar, measure 1 cup of water. Level the sugar with the back of a knife rather than heaping it; a heaped cup makes the mix stronger than the recipe calls for.
2. Decide whether to heat the water. Audubon’s recipe stirs the sugar into boiling water, and Penn State Extension says to bring the water to a boil and pour it over the sugar. The National Zoo says the water does not need to be boiled. The section on boiling below compares the two approaches.
3. Stir until the sugar is fully dissolved. The National Zoo’s instruction is to stir or shake the mixture until the sugar is fully dissolved in the water. Look at the bottom of the pot or jar; if grains are still sitting there, keep stirring.
4. Let it cool. Audubon’s steps say to cool the nectar before filling the feeder, and Penn State Extension specifies room temperature. Pouring hot nectar into a wide bowl lets it cool faster than leaving it in a deep pot.
5. Fill a clean feeder. Pour in only what the feeder holds, then hang it. The National Zoo advises cleaning the feeder thoroughly each time you change the nectar, to prevent harmful mold growth.
6. Refrigerate the rest for no more than a week. That is the National Zoo’s limit for extra sugar water kept in the fridge. If you see mold in the jar, the Zoo says to throw it away and make a new batch. Writing the date on the lid takes the guesswork out of it.

How Much to Make: Batch Sizes

Make enough to fill your feeders, plus a refrigerated reserve you will use within a week. The table below turns the one-to-four ratio into kitchen measures. The 1/4 cup row is Audubon’s batch; the half-cup, one-cup, and two-cup rows match examples the National Zoo gives; the 2 tablespoon row is Audubon’s batch cut in half (a quarter cup is 4 tablespoons).

Two practical notes. First, dissolved sugar adds some volume, so a batch made with 8 fl oz of water comes out a little over 8 oz. Put the extra in the fridge rather than overfilling the feeder. Second, check your feeder’s capacity on its packaging or product page instead of guessing: one feeder that holds 8 oz calls for the 1 cup batch, and two 16 oz feeders call for the 1 quart batch.

If the hummingbirds in your yard drink only part of a feeder between changes, fill it partway and mix smaller batches. Whatever is left in the feeder gets poured out at the next change, so a half-full feeder wastes less sugar than a full one.

How the Published Recipes Compare

Each cell below reflects what the organization’s page says; “Not covered” means the page does not address that point.

The agreement is the useful part. Four separate organizations publish the same proportion, and none of them adds vitamins, flavorings, or anything else to the sugar and water.

Should You Boil the Water?

This is the one place the recipes split. TPWD gives a reason for boiling: to slow down fermentation (rotting) of the nectar. The National Zoo says the water does not need to be boiled as long as the sugar fully dissolves, and it handles spoilage with a schedule instead: change and thoroughly clean feeders every other day, and at a minimum clean and refill them twice a week in hot summer weather and once a week in cooler spring and fall weather.

Our reading is that either method works when the rest of the recipe is followed. Hot water dissolves sugar faster, which helps with a quart or more, but you then have to wait for the nectar to cool before it goes outside. Room-temperature tap water skips the wait and needs more stirring. Neither approach replaces fresh nectar and a clean feeder.

Which Sugar to Use, and What to Leave Out

Use refined white sugar. Leave these out:

• Honey. Audubon says honey can promote dangerous fungal growth, and Penn State Extension warns that fermented honey can cause a fatal fungal disease in hummingbirds.
• Corn syrup and raw, unprocessed sugars. The National Zoo says never to use them.
• Powdered sugar. The National Zoo notes that confectioners’ sugar often contains other ingredients, such as cornstarch, and does not recommend it for hummingbird food.
• Red dye or food coloring. Audubon says it is not necessary and could prove harmful to birds. The National Zoo says it is not needed to attract hummingbirds and could be harmful. TPWD says that since it is not known whether food coloring harms hummingbirds, it is best left out.

If you want red at the feeder, put it on the feeder, not in the liquid. Penn State Extension says hummingbirds are attracted to the red coloring of the feeder itself, and TPWD says the red already on a feeder is plenty to attract them. The nectar itself can stay clear, which is why this recipe leaves the dye out.

Measure Instead of Eyeballing

The ratio is the whole recipe, so measure both ingredients. Penn State Extension says weaker sugar solutions will be less attractive to hummingbirds and stronger solutions may be harmful. The common slips are small ones: a heaped cup of sugar, a guessed splash of water, or a measuring cup for the sugar and a mug for the water. Use one measure for both, and keep the mix at one part sugar to four parts water.

Mistakes That Waste a Batch

• Filling the feeder while the nectar is still warm. Both recipes that use boiling water have you cool it first.
• Pouring fresh nectar on top of old. The National Zoo pairs every change with a thorough cleaning, which means emptying the feeder first.
• Mixing a gallon for one small feeder. With a one-week limit on refrigerated leftovers, most of a big batch for a single feeder ends up down the drain. Use the batch table above instead.
• Using a jar with mold in it. The National Zoo’s advice is to throw it away and start a new batch, not to strain it or top it up.

Homemade or Store-Bought?

Penn State Extension says commercial nectar mixes are available but are no better than those you make yourself. A mix can still make sense if you fill feeders away from a kitchen or want pre-measured packets; if you buy one, compare the sweetener, any added color, and the mixing directions on the label.

How We Put This Guide Together

We read the published hummingbird nectar recipes from the four organizations linked above and kept only statements we could match to their pages. Where they disagree, as on boiling, we show both positions instead of choosing one. The only numbers we added are plain conversions, such as tablespoons in a quarter cup and fluid ounces in a cup. Our general method is on the How We Review page.

Homemade Hummingbird Nectar FAQ

Is hummingbird feed the same thing as hummingbird nectar?

Yes. The National Zoo’s page uses “nectar,” “sugar water,” and “hummingbird food” for the same mix, and “hummingbird feed” is another common name for it. So how to make hummingbird feed comes down to the same recipe: one part refined white sugar to four parts water.

Can I use tap water?

Yes. The National Zoo says you can use tap water to make hummingbird nectar.

How do you make hummingbird nectar without a measuring cup?

Pick any container as your “part”: a coffee mug, a scoop, or a small jar. The National Zoo says a part can be any measurement as long as it stays equal. One scoop of sugar goes with four scoops of water, using the same scoop for both.

Can I use a sugar substitute or artificial sweetener?

No. Every recipe we cite uses sugar, and the National Zoo says to always use refined white sugar. A sweetener that is not sugar does not match any of them.

The Short Version

Measure one part refined white sugar to four parts water, stir until dissolved, cool, and fill a clean feeder. Keep extra in the fridge for no more than a week, leave out dye and honey, and size each batch to what your feeders hold.
