Hummingbirds have a long migration in which they travel enormous distances. By the time they arrive at the beginning of spring, they have little energy left. Your feeders can provide a desperately needed source of food. When combined with nectar, a “super nectar” blend can mimic the energy dense flowers that provide a rich energy source to help them Continue to sustain energy levels needed for survival.

One of the highest metabolism rates in the world can be found in hummingbirds. About 1200 times a minute while flying, their hearts need to work that hard to keep them in the air, that is the same as a hummingbird having to eat sugar equaling to 50% of their body weight, every single day. That amount of sugar is only to stay alive! Furthermore, during the spring, the birds need to migrate which is even more demanding.

Numerous species of hummingbirds migrate several hundred or several thousands of miles to their breeding grounds. For instance, Ruby-throated hummingbirds attempt to make a non-stop crossing of the Gulf of Mexico, a distance of over 500 miles and of 20 hours of duration. Upon landing, the first thing they look for is nectar to replenish their energy.
The nectar made by early spring flowers is from 20% to 30% sugar content, which is a lot of sugar. It is sweet water, but also as described, high-octane fuel to match the intense energy needs of birds. Your nectar is also a high energy food source, especially in places where natural flowers haven't fully opened yet. Providing good nectar early in the season is one of the most supportive things to do for hummingbirds during this critical time. It is one of the most demanding times in a hummingbird's life.
The Best Sugar-to-Water Ratio for Highest Energy
One part sugar to four parts water is the industry standard for making hummingbird nectar. This will create a sugar solution of about 20% which will match the nectar of most common hummingbird flowers. This ratio is also safe for hummingbirds as recommended by most wildlife organizations.
Some birders try a stronger 1:3 ratio during migration. This "super nectar" has about 25% sugar—similar to the richest flower nectars. The extra energy is beneficial for tired migrants or during cold snaps when hummingbirds are more active and burn calories faster to stay warm.
Here’s how to pick the best ratio option for your needs. If you will be feeding birds throughout the summer months, then the best option to go with would be the 1:4 ratio. This is because it will give the birds ample energy without being overly concentrated. If there are early spring arrivals or late fall stragglers, or if there is unseasonably cold weather, then consider a 1:3 ratio. In these situations, birds will need more calories. In addition, some specialists recommend this in regions where natural food sources are limited.
Caution: NEVER go stronger than 1:3. Sugar water that is too concentrated can harm hummingbirds, and may even cause liver and kidney damage. Also, never use honey, artificial sweeteners, brown sugar, or organic sugar. Use plain white granulated sugar only, as that is the most similar to natural nectar without the added minerals that could encourage the growth of dangerous bacteria.

Important
The 1:3 ratio is only for migration and cold snaps (under 50 degrees). Using it year-round stresses the kidneys of the hummingbirds. Default to 1:4.

While making hummingbird nectar is really easy, a couple strategies keep it fresh and safe. Start off by boiling the water. This allows the sugar to dissolve and also kills any bacteria or mold spores.
As the water heats, measure the sugar. For standard nectar, use one cup of sugar for every four cups of water. For super nectar use one cup of sugar for every three cups of water. Once the water is at a rolling boil, turn off the heat and stir in the sugar until it dissolves completely. The solution will be perfectly clear and no granules will be visible.
Before filling your feeders, be sure to let the nectar cool down completely. Filling your feeders with hot nectar can warp the feeders and even burn the tongues of the hummingbirds. You can help the nectar cool faster by placing the container in cold water or in the refrigerator, but never put any ice directly into the nectar since that will dilute your carefully measured ratio.
Keep any unused nectar in a sealed, covered container in a refrigerator. Nectar that has been made correctly will stay fresh in your refrigerator for two weeks, so store it there. Make sure to label your container with the date so that it will remind you when it is time to make a new batch.

Warmer temperatures mean you should change the nectar in your feeders every two to three days, even if some nectar is still left in the feeder. In springtime with cooler temperatures below 70°F , you may change the nectar every four or five days. Spoiled nectar can appear cloudy, moldy, or have black flecks… if you see these signs, replace the nectar immediately.

Using red dye in nectar is the largest mistake backyard birders can make. Even with decades of advertising, no one has proven that colored water is more effective than the red sections on bird feeders. There is no need to use food coloring as it has been said to have a negative impact on human health. Clear nectar works just as well as any colored product.
Do not use honey or organic sugar substitutes. Honey can carry fungal spores that may cause fatal tongue infections in hummingbirds. Organic and raw sugars have iron and other minerals that encourage the rapid growth of bacteria. Every time plain white sugar is the safest option.
Hygiene is extremely important when it comes to feeders. Feeders can grow bacteria, mold, and black mold, which can be dangerous and possibly fatal to the hummingbirds. Please clean your feeders every time you refill them. Scrub every inch with hot water and a bottle brush, especially the feeding ports where residue builds up. Tough cleaning jobs can be done using a solution of one part white vinegar to four parts water. Be sure to rinse everything thoroughly after you are done cleaning before you refill them.
To reduce spoilage of nectar and allow cooler temperatures, place feeders in partial shade. If you find ants, you can try an ant moat; a simple water barrier can keep ants from getting to the nectar. For feeders that attract bees and wasps, select ones that have bee guards or those that use a saucer design to keep nectar available to insects with short tongues.
Finally, commit to consistency! Hummingbirds rely on feeders, and if they find your nectar in the spring, they will return all summer to feed. Clean and refill the feeder throughout the summer. You may be providing the fuel these amazing birds need to complete their long migrations! Happy birding!
